Abstract:
This experiment was conducted with the aim to estimate the effect of plant growth regulators on fruit, seed morphology and yield in Neem. In this study we gave used five growth regulators with two different concentrations such as Naphthalene acetic acid, ethylene, mepiquat chloride, cycocel, and triacontanol. Plant growth hormones are organic compounds that influence the various physiological processes in trees when applied in minimum concentrations. On its exogenous application, it will quickly penetrate and will be easily absorbed by the plant tissues. The maximum values of fruit and seed morphological traits were recorded in the triacontanol at 1000ppm followed by ethylene at 1000ppm viz., Fruit length (20.87 mm), fruit width (13.89 mm), 100 fruit weight (134.19g), seed length (24.17 mm), seed width (7.27 mm), 100 seed weight (24.17 g). The tree treated with triacontanol at 1000ppm was maximum fruit yield (12.33 Kg) and seed yield (3.78 Kg).
