1. Introduction

The remains of almond, found in several archeological sites, show the importance of this crop since centuries. Being storable after drying, the fruits can be transported everywhere, this is the reason why, these nutritious nuts have followed the human migration. The easy adaptability of this species to poor soils has favored their spread. It is an elixir for good health and a panacea for all ills. Almonds have long been an integral part of India’s cultural heritage, especially during festive seasons and weddings. In an increasingly health-conscious nation like India, the demand for almonds is ever increasing. However, several problems plague production and limit output which has led to high import.

1.1. Nutritional value

Almonds are good source of fat, in which 80% is in the form of monounsaturated fatty acids (MUFA) which decreases unwanted cholesterol of body. Almonds contain omega-6 fatty acid which is good for heart. The amount of saturated fat is very less in almonds. Almonds have high amount of phosphorus and calcium which is required for bone growth. Magnesium, manganese, vitamin B6 and Vit. E are also available in almonds. Almond oil contains glucosides, minerals, vitamins and is rich in protein. Nutritive value of almond has been presented in Table1.

1. Introduction

The cultivated apple (Malus × domestica Borkh.), is the most important fruit in temperate regions of the world. Apples were frequently used in different mythologies as symbols of immortality or reincarnation. One of the most popular stories attached to apple is that of Adam and Eve, who ate the forbidden fruit from the tree of good and evil which was in the center of the garden of Eden. The Latin word Malus has two meaning i.e. apple and evil, which has probably stemmed from this story from bible. In Greek mythology, mother earth or Gaia, presented a tree with golden apples to Zeus and his bride Hera on their wedding day. These golden apples were later indicated with many stories of love, bribery and temptation ranging from the abduction of Helen of Troy to the defeat and marriage of Atlanta. Goddess Pomona was deity of fruit trees in Rome. In many cultures, garden of paradise and pleasure is symbolized as the place with fruit-laden apple trees. Apple is popular because of its delicious taste and pleasant aroma.

1. Introduction

Apricot is among the highly nutritious fruits of Rosaceae family and appreciated for its health promoting contents. Studies have shown that apricot fruit is effective in preventing stomach ulcers and oxidative damages of living systems (Enomoto et al., 2010; Miyazawa et al., 2006). Apricot tree belongs to genus Prunus in the Rosaceae (rose) family. Apricot (Prunus armeniaca) is categorized under ‘stone fruits’, along with peaches, plums, almonds, and some cherries, due to its seed being enclosed in a hard, ‘stone’ like endocarp. This fruit is native to temperate Asia, first discovered growing wild on the mountain slopes of China, and long cultivated in Armenia later.

Throughout its history, apricot has been noted for delicious flavor, delicate velvety fruit surface, and early flowering and fruiting. The name apricot is a corruption of the Arabic and Greek al-paraecox which means the early fruit. The old spelling ‘apricock’ is retained in English until the 17^th century. The fruits are mainly consumed fresh but are also cooked and often stuffed. The high sugar content makes them suitable for drying. In china they were also preserved by salting and smoking. Other uses include fruit leathers, nectars, and liquors (Janick, 2005).

1. Introduction

Cherry is the common name of several Prunus species that include sweet cherry (P. avium), tart or sour cherry (P. cerasus), Duke cherry (hybrids between P. avium and P. cerasus). Sweet cherries are believed to have originated from the area between the Black and Caspian seas of Asia Minor. Birds probably carried the seed to Europe prior to human civilization. Cultivation was probably started by the Greeks and continued by the Romans. Its distribution and naturalization have proved extensive, for it is now found wild in areas as widely spaced as northern India, the southern plains of Europe and even on isolated islands such as Madeira. Climatic conditions are the most important limitations on cherry production. Being a deciduous tree, it needs a period of dormancy, which is initiated in temperate regions mainly by a fall in average temperatures in late autumn (Mir et al., 2017). Sweet cherry is grown almost everywhere in the temperate zone. It is a composite genus. Due to its origin, this genus needs warm and light conditions, but can also endure cold winter weather. It requires 550-600 mm precipitation annually. Sweet cherry prefers medium light (pH= 5.5–7.5), deep-layered soil, which is rich in nutrients. The root system of sweet cherry requires aeration and cannot tolerate slack water (Simon, 2004). Many areas of the world, although environmentally suited to cherry production, are currently unsuited to profitable cherry production due to high perishable nature of the fruit.

1. Introduction

Hazel nut also called as European filbert or Bhotia badam (Corylus avellana L.). Apparently the word ‘filbert’ has been derived from Middle English which in turn was a derivation of Philbert - the Saint Philibert, whose feast day in late August coincides with the ripening of the nut. Others believe that the term filbert came from the nut’s long husk being referred to as a full beard in Old English. The name “Hazel” comes from the Anglo-Saxon word for bonnet, “Haesel”; this probably derives from the greek “korys” (as in Corylus), for helmet or hood. The term “filbert” may have derived from “full beard”, descriptive of the long, leafy husk. The scientific name avellana derives from the town of Avella initially and was selected by Linnaeus from Leonhart Fuchs’s De historia stirpium commentarii insignes (1542), where the species was described as “Avellana nux sylvestris” (“wild nut of Avella”). Hazelnut is the 4^th economically important nut crop (748,000 MT/yr) of world after cashew, almond and walnut.

1. Introduction

Kiwifruit (Actinidia deliciosa Chev.) is among the most recently domesticated of all fruit plants. The kiwifruit of international commerce are large – fruited selections of Actinidia deliciosa Planch and Actinidia deliciosa (A. Chev.) C F Liang et A. R. Ferguson, belongs to family Acitinidiaceae. A. chinensis has been cultivated commercially for little more than 20 years, however, A. deliciosa for about 70 years. This is known as “China’s miracle fruit” and “Horticulture wonder of New Zealand”. Although this fruit vine originated in China, yet its full economic potential was exploited by the New Zealanders, which accounts for over 70 per cent of world trade (Franco, 1990). Kiwifruit has completely replaced the older name of ‘Chinese gooseberry’. In China, ‘Mihoutao’ (monkey peach) is used for all Actinidia species, but as A. chinensis and A. deliciosa are by far the most important economically of the various Actinidia species in China, they are often simply referred to together as Mithoutao. More explicitly, the two species are sometimes referred to together as Zhonghua (Chinese) Mihoutao. In other countries of the world, its cultivation gained momentum after 1960s and now is cultivated on a commercial scale in USA, Italy China, Japan, France, Germany and Australia.

In India, it was first introduced in 1960 at Lalbagh garden, Bangalore, but the plant did not come into bearing due to lack of chilling requirement during winter for its bud break. Later on, in 1963, it was introduced in Shimla hills, where the plant came into bearing in 1969. In order to assess the performance of kiwifruit cultivation in different agro-climatic conditions of state its plantation were done at different locations. After evaluation, this fruit was recommended for commercial cultivation in mid and low hills of the state. It can also be grown in mid hill of Jammu and Kashmir, Uttrakhand, Sikkim, Arunachal Pradesh, Meghalaya, Nagaland and Nilgiri hills of south India.

1. Introduction

Olive (Olea eurpaea L.) is an evergreen species commonly grown in the Mediterranean basin. The oil extracted from the fruit is a predominant component of the ‘Mediterranean diet’, which has documented heart- and cancer-protective benefits. These derive from the lipid composition and from biologically active molecules that accumulate during olive fruit development. The oil can reach up to 30% of the total fruit fresh weight at full ripening and is highly present in the mesocarp and at lower levels in seeds. Oil increase reaches a plateau in pulp after varaison. A marked triacylglycerol accumulation in seed and pulp occurs after endocarp lignification, when about 40 mg of oil per fruit per week can be synthesized. The fatty acid profile of the oil accumulating in the fruit is important in relation to its nutritional properties. The main fatty acid is oleic acid (C18:1), which represents about 75% of total fatty acids, followed by linoleic (C18:2), palmitic (C16:0), stearic (C18:0) and linolenic (C18:3) acids (Martinelli and Dandekar, 2014).

The olive, Olea europaea L, is the only species of the botanical family Oleaceae with edible fruit. The tree blooms with small white flowers in May, and fruit set begins almost immediately afterward in May or June. Ripening is complete toward the end of November or December, depending on the variety. Its cultivation began more than 6000 years ago in the Middle East, and spread west on both sides of the Mediterranean Sea.

1. Introduction

The peach [Prunus persica (L.) Batsch] is an important fruit crop of temperate regions, all over the world. Important centers of commercial production usually lie between latitudes 30° and 45° North and South. At higher latitudes, minimum winter temperatures and spring frosts are the limiting factors. The peach flower bud is hardy and can tolerate minimum temperature of about -23 to -26° C. Its northern range is extended where minimum temperature are ameliorated by large bodies of water, as western continental seaboards, the great Lakes in the U.S.A. and Canada and the Caspian and Black seas of Eurasia. Mid continental areas are characterized by lower winter temperatures and usually more severe spring frost hazards. Most peach cultivars require 500 to 1000 chill hours below 7.2° C to foliate and bloom. At lower altitudes, the winter requirement is not met. The peach with its smooth skin mutant is known as nectarine. Nectarines can be used in the same way as peaches, and may be considered as substitutes for peaches.

1. Introduction

Pear is among the oldest of the world’s fruit crops, figuring in both Bible and the tales of Homer. They are by far the most important of the deciduous tree fruits, are widely grown in temperate and increasingly, in tropical regions, and figure prominently in world trade. The fruit is primarily grown for the fresh fruit market, which is much more remunerative than that for processing.

Pear (Pyrus communis, Rosaceaea family), is a deciduous fruit, grown under a wide variety of climatic regimes, ranging from cold dry temperature hilly conditions to warm humid subtropical conditions. It is grown in many places of India like Jammu and Kashmir, Himachal Pradesh, Karnataka, Tamil Nadu, Kerala, Utter Pradesh. Sandy pear plants were brought to Amritsar by travellers from China who settled at Harsha Chinna village near Amritsar about 2,500 years ago. The Kashmir valley represents one of the major Pear (Pyrus communis.L.) growing areas of the world. Pear was introduced in India from China. The time at which Pear was introduced to Kashmir is not precisely known, however Yukteshwar Kumar writes in his book “A History of SinoIndian Relations” that peach and pear came to India during the early years of the Eastern Han period (25 AD to 220 AD). This pre historic fruit has been under cultivation both in Europe and Asia for about 3000 years (Hedrick et al., 1921). Between 16^th and 18^th centuries, many European writers travelling Kashmir noted fantastic royal gardens of the Mughals, mentioning the abundance of peach, pear, plum and cherry trees, with fountains spouting cold, icy water. Pear (Pyrus communis. L), originating from the German word ‘peer’ meaning fruit, is a fascinating fruit steeped in rich history. This fruit is known as ‘tang’ in Kashmiri language. Low chill requiring pears are being cultivated in plains of North India. Cultivars requiring high chilling hours (900-1000) are cultivated at higher hills of Jammu and Kashmir, Himachal Pradesh and Uttarakhand. Majority of the Pear production is actually limited to Kashmir however, low chilling cultivars grow in subtropical regions.

1. Introduction

Pecans (Carya illinoensis) are one of the most desirable trees to plant in home yards. Their size and natural beauty as a shade tree and its capacity to produce a nutritious food make them valuable. Pecan is the most widely cultivated and the most economically important member of the North American hickory group. Beyond its native range, pecan is commercially grown from the southeastern USA to the south-west (California) (Hanna, 1987, Peterson, 1990, Harlow et al., 1991). Pecan is from an Algonquian word, meaning ‘a nut requiring a stone to crack’. In Mexico, pecans and walnuts share the same Spanish name, neuz, which is a cognate of the English word nut. In the USA, pecan is considered the queen of nuts because of its value both as a wild and as a cultivated nut and acceptable quality of meats (Woodroof, 1979). Pecan is also considered as ‘queens of nuts’ because of its value both a wild and as a cultivated nut and acceptable quality of meats. As compared with other nut fruits which have been grown since time immemorial, pecan has been under cultivation only for about one hundred years but has gained enormous popularity.

The pistachio nut tree, Pistacia vera L. has been extensively cultivated since ancient times in the Middle Eastern and Mediterranean countries; in India, Afghanistan. The climatic conditions favorable to pistachio culture are similar to those for almond and olives, and prevail in extensive regions of the western United States also. Pistachio is a nut which comes originally from Iran and has the history of 4000 to 5000 years. Pistachio is a drought-tolerant, slow-growing, deciduous tree that reaches to a height of 30 ft. The tree survives in arid regions where summers are hot and the winters cold. Rocky, poor terrain with little rainfall is no problem as long as there is good drainage. The fruits grow in clusters. Although called a nut, botanically, pistachios are actually drupe. The pistachio consists of a bone ivory shell that encases the edible meat portion, called the seed.

Plum is one of the important stone fruit crops of temperate region throughout the world. The Japanese group of plum is native to China but was domesticated in Japan and subsequently was introduced to different parts of the world. In India, Japanese plums were introduced by European settlers and missionaries around 1870. Plum grows well in areas ranging from 900 m to 1600 m above mean sea level.

1.1. Uses

Among deciduous fruits, plum is widely distributed in the world, because of wider adaptability among different species and cultivars of plum to varied agro-climates and soil conditions. Plum is consumed as dessert, dried and processed products. Plum fruit is considered best to overcome the jaundice. Its fruit use for a preparation of juice and squash. It ranks next to peach in commercial production. It is widely cultivated in several countries in Europe, Asia and in the America.

1. Introduction

Quince is a highly nutritious underutilized fruit of sub-Himalayan region which has great economics and medicinal potential and it belongs to the group of the oldest cultural plants. Quince is known with different names, Urdu name ‘Bahee Dana’, Farsi name ‘Beh’, Greek name ‘Strythion’, Kashmiri name ‘Bamchunth’ and Hindi name ‘Bihi’ (Torkelson, 1995, Khoubnasabjafari and Jouyban, 2011). Quince is very much like pear in shape and gets a golden yellowish outer layer when mature. Quince fruit is a valuable dietary product and even then it less suitable for the direct consumption (Hricovsky et al., 2003) and for that reason they are mostly used either cooked (Alvarenga et al., 2008) or preserved (Kyzlink, 1990). However, as compared with other species, this fruit tree species is less popular throughout the world. Its predisposition to turning brown and decay is a limiting factor in the long-term storage of this fruit (Gunes, 2008). The nutritional value of the fruit is high (Bucsek et al., 1996; Kopec and Balik 2008). It is well known that quince fruit shows antioxidant effects (Silva et al., 2002) which result from the presence of a number of polyphenolic substances (Fattouch et al., 2007), e.g. flavonoids quercetin, rutin, kaemp ferol etc. (Silva et al., 2005), and also from increased levels of vitamin C (Tetera, 2006). Quince has the important nutritional and flavor composition more than many fruits. Vitamin C content of quince is nearly two times higher than in apple (Biro and Lindner, 1999).

The modern cultivated strawberry (Fragaria x ananassa Duch.) is one of the most delicious, refreshing and soft fruits of the world. Worldwide it is also the most widely distributed fruit-crop due to its genotypic diversity, highly heterozygous nature and broad range of environmental adaptation. The plant is cherished in gardens and in commercial fields for its beautiful red fruit that has a tentalizing aroma (Sharma, 2002; Sharma and Sharma, 2004). Being a rich source of vitamins and minerals coupled with delicate flavour, strawberry has now become an important table-fruit of millions of people around the globe. It is amongst the few fruit crops, which gives quicker and very high returns per unit area on capital investment, as the crop is ready for harvesting within 6 months of planting. However, due to several technological advances in its cultivation like, introduction of day-neutral cultivars, and protected cultivation, strawberries remain available as fresh fruit throughout the year.

At present, strawberry is grown in wide climatic zones, extending to temperate, Mediterranean, sub-tropical and taiga zones (Sharma, 2002; Sharma and Sharma, 2004). Its cultivation is influenced by the specific regional adaptations due to critical photoperiods and temperature requirements and thus its cultural systems are highly variable. Due to the constant efforts of strawberry breeders, the world-wide interest for strawberry cultivation has boosted its production tremendously, which has resulted in widespread popularity of strawberry in the last 50 years.

1. Introduction

Persian walnut is of great importance across worldwide where nuts are harvested from wild stands, backyard gardens and rarely from commercial orchards that vary considerably in their size due to degree of management. The walnut is an old tree cultivated before the Greek age and appreciated for centuries for its fruits, wood and other parts utilized in several ways. Before the discovery of the phenomena of allelopathy, someone considered the walnut an un-healthful tree, since peasants used to wake up with migraine or fever after they had slept under a walnut tree. Some others considered the walnut a cursed tree, and in fact in Italy an old walnut tree growing in Benevento, has long been considered the place where the witches used to dance during the night of Saint John and, therefore, that tree was named “Tree of the Witches” (Avanzato, 2010).

Nuts are collected for home consumption, sale at local roadside stands and markets and for shipping to cities. Walnut trees are further utilized for their high quality timber to make a wide array of products. The leaves, bark and other plant parts are used for medicinal remedies and trees are grown and maintained for soil conservation purposes (Mamadjanov, 2006b). A diverse mix of seedlings, local selections, and advanced cultivars are grown for nut production, many with unknown origins, including some of which are the direct result of selection from the wild.

In domestic animals, skeleton (Fig. 1-1) is a framework that is formed of bones, cartilages and ligaments binding together giving the specific shape, form and support to the body. In addition, the skeletal framework surrounds the major cavities of the body giving protection to other soft visceral organs of the body. There are three major parts of skeleton in the animal body (1) the axial skeleton (2) the appendicular skeleton and (3) the splanchnic skeleton.

The axial skeleton consists of the skull, vertebral column, ribs, and sternum. The appendicular skeleton consists of the bones of fore limb and hind limb

The splanchnic skeleton includes some of the bones embedded in the substance of visceral organs in the body such as os cordis in ox and os penis in dog.

Bones

The bones forming the skeleton of the body are of different shape, size, form and the constituting tissue material. The number of different types of bones of any species may differ in various stages of the growth of the animal. So also the numbers of various bones differ from species to species.

A branch of anatomy that deals with joints or articulations in the body is termed as arthrology or syndesmology. A joint is an articulation or union formed by two or more bones or cartilages with the help of connective tissue. To form a joint, the long bones meet at their extremities e.g. joints of fore limb and hind limb. Joints of flat bones are formed by their borders or edges e.g. joint of bones of skull, the cranial and facial bones. The short bones and irregular bones form a joint by uniting at any of their parts or surfaces e.g. intervertebral joints.

Classification of joints

Joints are classified on the basis of their structure i.e. the kind of tissue material by which the bones are united, the other constituent parts that help in uniting the bones and the kind of movement performed at that joint. On this basis, the following three major types of joints exist in the skeleton of animal body.
