Crop-Scientific Studies on the Yield-Formation and the Yield-Forecast of Lowland Rice : XXXVI. On Forecast of the Number of Spikelets per Panicle

Abstract

After finding out the high correlation coefficient between the number of spikelets on a panicle and the thickness of the first elongated inter-node at the base of the culm, the authors have traced up the growing process in thickness of the first elongated inter-node, ascertaining its growth atains a maximum at the stage of spikelet primordium differentiation. Basing upon these facts, a valuable and interesting method has been found out to forecast the number of spikelets per panicle.
