Synchronization of flowering of diverse genotypes of (Cajanus cajan L. Millsp.) by plant growth nutrients

Published on

Synchronization in flowering of diverse genotypes of
pigeonpea was studied by using eight chemicals. It was
found that Ethrel, MH, NAA, and KN03 delayed the flowering
while GA, SA and K2H2P04 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.
