Abstract

he accumulation dynamic of filling matter for spikelets at different positions within a rice panicle was investigated during grain filling to understand the physiological reasons for the variations of grain quality. Two rice cultivars, Yangdao 6 (indica) and Yangjing 9538(japonica), were fieldgrown, and the grain filling character and the contents of starch, soluble sugar, and protein of the spikelets at different positions were studied. There were significant differences in matter accumulation between spikelets at different positions during grain filling. The earlierflowered spikelets presented dominance over the laterflowered spikelets in initial filling rate and filling intensity. The contents and rates of starch and amylose accumulation in spikelets were consistent with the flowering sequence at the initial and medium filling stages, i.e., the earlierflowered spikelets had greater contents and rates of starch and amylose accumulation than laterflowered spikelets, but the soluble sugar content (SSC) exhibited an opposite result. The difference in SSC between the spikelets of Yangjing 9538 was greater than that of Yangdao 6, but the amylase content in spikelets at maturity was not very identical with the flowering sequence of spikelets. The change in crude protein content (CPC) showed an Sshaped curve. The CPC of earlierflowered spikelets decreased more rapidly than that of those laterflowered ones at the initial filling stage, and CPC in the spikelets on the secondary rachis branch was more than that on the primary rachis branch, but CPC in laterflowered spikelets was higher than that in earlierflowered spikelets in the whole filling period. Grain water content (GWC) of earlierflowered spikelets decreased more rapidly than that of laterflowered spikelets in the same branch at the initial and medium filling stages, especially for the first grain among the spikelets on a primary rachis branch. The results suggested that the low biological activity of laterflowered inferior spikelets may be attributed to their poor grain filling rather than carbohydrate supply.
