The Jamun Tree in India is also known as Nerale Hannu, Jamblang, Jambolan, Black Plum, Damson Plum, Duhat Plum, Jambolan Plum, Java Plum or Portuguese Plum. "Malabar plum" may also refer to other species of Syzygium. According to Hindu tradition, Lord Rama subsisted on the fruit in the forest for 14 years during his exile from Ayodhya. Because of this, many Hindus regard Jamun as a 'fruit of the Gods, ' especially in Gujarat, where it is known locally as jamboon.
Description of Jamun Tree
The Jamun Tree in India has some long leaves that hang from the above. They crowd near the end of the branches and bear up to a number of leaflets that count 29 to 31. Each of the leaves is about 7.5 cm in length, severely jagged, sharply pointed and curvy like a sweep. Their surface is fresh, green in colour, and very shining. It gives the tree a delicate and appealing view. During the monsoon, the flowers fall down and the tree gets in full flora. To recognize easily, the curved and notched leaves mass around the branches and make a distinguishing appearance.
Favourable Conditions for growing Jamun Tree
The Jamun Tree in India thrives best in the dry areas. Since Jamun is a hard fruit, it can be grown under adverse soil and environment. It seeks dry weather at the time of flowering and fruit setting. Early rain is good for better growth, development and ripening of fruit. Young plants are susceptible to frost.
The Jamun trees are grown on a wide range of soils-calcareous, saline sodic soils and marshy areas. Deep loam and well-drained soils are, however, beneficial. It does not require very heavy and light sandy soils.
Species of Jamun tree
The Eugenia genus encompasses a diverse assemblage of approximately 1,000 evergreen tree and shrub species, predominantly hailing from tropical regions. Notably, certain former Old World Eugenia species have been reclassified into the Syzygium genus. This taxonomic group falls within the Myrtaceae family. A significant proportion of these species bear edible fruits, with select varieties possessing ornamental and medicinal attributes.
Among these, the species S. fruticosum emerges as a noteworthy example, valued for its diminutive edible fruits and employed for windbreak cultivation. This substantial evergreen tree bears compact dark purple fruits characterized by conspicuous elongated seeds. Even in its ripe state, the fruit retains astringent properties inducing tissue contraction. A well-regarded member is the S. jambos, commonly referred to as the rose apple or gulab-jamun. Indigenous to South India and West Bengal, this tree boasts both ornamental and gustatory qualities.
Prevalent in North Indian conditions is the "Ram Jamun" variety, recognized for its substantial, oblong fruits that assume a deep purple or bluish-black hue upon full ripening. The ripe fruit's pulp presents itself in shades of purple-pink, exuding a juicy and sweet character while harboring a comparatively small stone. Alternatively, a tardier maturing cultivar produces smaller, slightly rounded fruits which attain a deep purple or blackish color upon full ripening. The pulp takes on a purple tone, possessing diminished juiciness and pulp weight as well as sweetness when compared to the 'Ram Jamun'. Notably, the stone in this variant is comparatively larger. Contemporary circumstances present a rich diversity of jambun seedling strains within India, effectively offering a fertile ground for the selection and propagation of improved variants.
Propagation of Jamun Tree
The propagation of the Jamun tree encompasses a range of techniques, spanning from seed propagation to various vegetative methods. The unique feature of polyembryony within the Jamun seed allows for true-to-parent outcomes through seed propagation. Although some success has been achieved with vegetative methods, seed propagation remains the preferred approach, notwithstanding its potential for delayed fruit-bearing.
The seeds of the Jamun exhibit no dormancy, and their immediate use is recommended. Germination typically occurs within a span of 10 to 15 days. Once germinated, seedlings can be transplanted as rootstock either in the subsequent spring months (February to March) or during the monsoon period, spanning August to September.
The process of propagating the Jamun tree is both economically viable and convenient. Budding is a commonly employed technique, particularly on one-year-old seedling stocks boasting a diameter of 10 to 14 mm. The optimal timeframe for budding falls between July and August in regions with minimal rainfall. In areas characterized by abundant and early rains, budding activities are initiated as early as May-June. A trio of successful budding methods, namely shield, patch, and forkert have emerged. Among these, the forkert method has demonstrated superior efficacy in comparison to shield or 'T' budding.
While less prevalent on a commercial scale, the inarching technique is another avenue for Jamun propagation. This method involves the grafting of one-year-old seedlings, nurtured in pots, onto mature Jamun trees with the assistance of wooden supports. This procedure typically takes place during the months of June and July. For propagation through cuttings, the Jamun tree thrives under intermittent mist conditions. Semi-hardwood cuttings, measuring 20-25 cm, sourced from the spring growth of both S. jambos and S. javanica species, yield optimal results when planted in July and treated with 2000 ppm IBA.
Uses of Jamun bark
The bark derived from the Jamun tree stands as a versatile natural resource, characterized by both acrid and sweet properties.
