Artocarpus lacucha is a deciduous Asian fruit tree known as lakoocha and monkey jack. It develops a dense, spreading crown and is grown or gathered mainly for its edible fruit. [3] GBIF lists Artocarpus lacucha as an accepted species. [4]
Description
The tree is usually about 6–18 m tall and develops a broad, dense crown. Its native habitats include evergreen, semievergreen, and moist deciduous forests; limestone mountain forest is recorded in southern Yunnan, and the species occurs to about 1,800 m in other parts of its range. [3]
Cultivation
Soil and water
In nature, Artocarpus lacucha occurs in forest soils, including limestone mountain settings. Begin with deep, permeable soil that holds moisture without remaining stagnant. Maintain dependable moisture during establishment, especially for container plants, while preserving good drainage. [3]
Sun and humidity
The species is associated with humid tropical conditions. Young plants benefit from shade and a sheltered site; keep new plantings evenly watered while they establish before exposing them to more open conditions. [3]
Seasonal changes
The tree is deciduous, so irrigation and protection should follow the seasonal rhythm of the local climate. During a drier interval, maintain even moisture for young trees and container specimens without turning the root zone stagnant. Flowering and harvest timing vary with locality and plant condition. [3]
Propagation
Seed loses viability quickly and is best sown as soon as it is ripe. Fresh seed germinates best at about 24–27 °C; seedlings can be raised in containers and planted out at roughly 20–25 cm tall. Root cuttings and air layering are also recorded propagation methods. [3]
A laboratory study published under the name Artocarpus lakoocha compared BAP and meta-topolin on MS medium. BAP gave better shoot multiplication; 0.5 mg L−1 BAP produced a reported mean of 5.42 shoots, 2.25 cm shoot length, and 2.48 nodes after six months, while higher concentrations produced callus. This result describes an in-vitro experiment and does not validate outdoor root-cutting or air-layering performance. [5]
Flowering, fruiting, and harvest
Fruit is gathered from wild trees and sold in local markets in parts of the range. Harvest timing follows locality and plant condition rather than a single schedule. [3]
Fruit and uses
The fruit has a pleasant sub-acid flavor and may be eaten raw; it is also used in curries and chutneys. Fruits may reach about 7.5 cm in length. The male inflorescence is acidic and astringent and is sometimes pickled or included in curry mixtures. [3]
