The studies revealed that the median dates for vegetative flushing, cessation of growth, panicle emergence, date of full bloom and date of fruit maturity were different in different cultivars. Early emergence of panicles resulted in better yield and quality in Amrapali, Mallika and D-51 whereas, early maturity of fruits was found to be associated with the best yield and quality of Chausa. Further, acrotonic and lateral position of the growth unit was also found to influence yield and quality at different canopy positions of all the varieties studied. The mother growth units which were vegetative during the previous fruiting season were found to be more productive due to their better C: N ratio. The level of growth of the mother growth units after harvest also influenced the yield and quality of all the varieties. The best yield and quality in Amrapali and Mallika cultivars were observed when the vegetative mother growth unit flushed twice after harvest. In D-51 and Chausa the vegetative mother growth units which flushed only once after harvest resulted in the production of the best yield and fruit quality. In all the cultivars, Amrapali, Mallika, D-51 and Chausa, fruit yield and quality were found to vary w.r.t. temporal tree phenology and structural characteristics of the trees.EnglishThesis
