Abstract

                                Reduction in leaf area (source size) by removal of different leaves enhanced spikelet sterility of rice in the order, all leaves (64.3)> fieg leaf (38.8) second leef 3rd leaf 4th leaf (27.5)-28,9) control (25.6). Defoliation combined with shading of different plant parts also indicated that leaf is an important organ in deciding sterility. Panicle tailoring studies indicated that reduction in spikelet number (sink size) especially the lower 1/3rd spikelets of a panicle, reduced sterility in the remaining spikelets.
