Abstract

Study was conducted to find out the affects of growing degree-days (GDD) on the phenology and physiology of Brassica juncea and B. napus. Both were sown at five different dates at an interval of 15 days and Total Dry Matter (TDM) accumulation and its partitioning in stem and leaf were observed along with days to flowering and extent of pre and post flowering periods at different dates of sowing. It was observed that advancement of sowing dates changed the GOD requirement a10ngwith the flowering time but the GOD requirement for flowering irrespective to sowing dates in a species remained unchanged. Flowering time has a marked influenced on post-flowering period and TDM accumulation as well as it partitioning into stem and leaf.
