Abstract

Synchronization in flowering of diverse genotypes of pigeonpea was studied by using eight chemicals. It was found that Ethrel, MH, NAA, and KNO3 delayed the flowering while GA, SA and K2H2PO4 hastened the flowering in all genotypes. Maximum delay in days to 50% flowering by 15.1 days was observed with 0.02% Ethrel while maximum acceleration of flowering by 13.5 days was accomplished with 0.01% GA. Synchronization of flowering between untreated male-sterile lines with the treated pollinator lines was achieved in the present study.
