Effect of BAP (6-Benzylaminopurine) and NAA (α-Napthalene Acetic Acid) treatment on Micropropagation of Adansonia digitata L.

Abstract

The African Baobab, also known as Kalpvriksha (Adansonia digitata L.), is a significant multi-purpose tree that has gained popularity among people, primarily in African countries, for its use as food, fodder, clothing, and ropes. There is one of the obstacle arises in growing this plant by farmers in India is the lack of planting materials. The young plants of A. digitata L. have to be imported form selected nurseries. Therefore, micropropagation can be used as a substitute method to create offspring that are genetically similar to the parent plant. In order to micropropagate Kalpvriksh (A. digitata L.), this experiment is being conducted utilizing shoot tip explants. For shoot proliferation, these explants are grown in MS medium containing various concentrations of BAP (6- Benzylamino purine): 0.5, 1.0, 1.5, 2.5, 5.0 mg/L. Shoots are rooted in a medium containing at the same concentration of NAA (α-Napthalene Acetic Acid) 0.5 mg/L alone or with combination. Complete Randomized Design (CRD) is used to conduct each experiment. ANOVA and the Duncan New Multiple Range test are used to examine the data. According to the technique for micropropagation of A. digitata L. The concentration of BAP and NAA was found to be 1.5 mg/L and 0.5 mg/L respectively which showed better enhancement for shoot regeneration and rooting for micropropagation of Kalpvriksha (Adansonia digitata L.) tree.
