Micropropagation of Capparis decidua through In Vitro Shoot Proliferation on Nodal Explants of Mature Tree and Seedling Explants
In vitro clonal propagation of Capparis decidua was achieved using nodal explants from mature trees, and cotyledonary node, cotyledon and hypocotyl explants taken from the seedlings. Explants cultured on MS medium supplemented with BAP showed differentiation of multiple shoots and shoot buds in 4–5 weeks in the primary cultures. The medium with BAP (5 mg/l) was the best for shoot bud proliferation from the nodal as well as seedling explant. Shoot multiplication was best on cotyledonary node. In the nodal explants shoot multiplication was best on medium supplemented with 5 mg/l BAP and after second subculturing further multiplication of shoot buds was highest on the medium containing 3 mg/l BAP. Shoots were separated from mother cultures in each subculturing for rooting. Rooting was best achieved using 1 mg/l IBA in the medium. Rooted plantlets were transferred td earthen pots with garden soil and peat moss mixture.

Shoot and Plantlet Formation in Organ and Callus Cultures of Albizzia lebbek Benth
Plantlets were produced in vitro from root and hypocotyl explants taken from seedlings of the tree legume, Albizzia lebbek. These explants formed shoots when cultured with 5.0 mg l −1 kinetin and 1.0 ng -1 IAA in MS medium. Shoots were also induced in large numbers from callus treated with benzylaminopurine. About 20 per cent of the shoots rooted and were grown into plants
