Abstract

An index incorporating the rates of plant growth and development (thermal interception rate, TIR) was used to analyse spikelet and grain number in pearl millet. Growth rate was assumed proportional to solar radiation intercepted and developmental rate to the accumulation of degree days above a previously determined base of 10°C. The final number of spikelets was less sensitive to TIR than the final number of grains/plant. The critical period for the determination of grain number was from floral initiation to anthesis
