Groundnut flowering was analyzed on plants whose growth was modified by changing planting density or by shading exposure during different periods of the growth cycle. Flowering was assessed at the level of the plant branch and inflorescence. The results showed that flowering progression along the branch reflected the flowering dynamics of the entire plant. The number of flowers produced was determined by the rate of progression of flowering along the branches and by the period from the beginning to the end of blooming. These features were closely dependent on plant growth conditions. Increasing the planting density slowed the flowering rate and shortened the blooming period.This allowed a better synchronization of pod maturity. Exposure to shade before flowering decreased the rate of production of flowers but prolonged its duration uhereas exposure at mid-flowering halted flower production. It is suggested that the different reproductive organs (flowers and pods) may compete for assimilates, thus explaining the various effects observed on daily flower production.
