Abstract


A study was conducted to investigate the effect of soil drenching with paclobutrazol and foliar sprays of certain chemicals and growth regulators on the activities of certain enzymes viz., catalase, peroxidase, nitrate reductase (Nrase) and IAA oxidase on the yield of alphonso mango. The result revealed that the increase in the peroxidase and catalase activity has led to the increased chlorophyll metabolism thereby enhancing the yield in off seasons. The increase in Nrase had brought about better growth and development while the decrease in the IAA oxidase had led to high auxin content at the time of flowering resulting in high flowering and fruit set during off-years in alphonso mango.
