Title: Effect of Flowering Sequence of Spikelets on Endosperm Cells and Grain Quality of Rice
Abstract: Using different rice cultivars as materials, effect of flowering sequence on endosperm cells (ECs) and grain quality was analyzed. The results showed that with the delaying of anthesis of spikelets in a panicle, ECs decreased, chalky percentage (CP) and chalkiness (CN) increased while gelatinization temperature (GT) and amylose content (AC) decreased. Grain qualities significantly correlated with ECs, but not significantly correlated with single endosperm cell weight. ECs and GT increased significantly while CP and CN decreased when removing 1/2 plants at booting stage or spraying 6 BA [6 (benzyl) adenine] at early heading stage, and the results were reversed when cutting 1/2 leaves at booting stage. These results suggested that the difference of ECs resulted in different rice grain quality.The approaches to improving rice grain quality were discussed.
