Kumaran, K. | Palani, M. | Jerlin, R. | Surendran, C.
The effects of GA (gibbrerellic acid), indole acetic acid (IAA), kinetin (KM) and chlorocholine-chloride(CCC) at 200ppm and 400ppm concentrations on seed germination and seedling growth of Azadirachta indica were determined. Seeds were soaked in the solutions for 24 and 48 h and water soaked seeds served as control. Results indicated that the germination was enhanced by KN, with the highest germinationat KN-200 ppm. The seedling growth in terms of root length, shoot length and number of leaves was greatly enhanced by CCC, the effect being higher at 400 ppm concentration and 48 h soaking period.
