据报道,我国科学家日前通过研究证实,原始的“稻花”(水稻小穗)由三个小花构成,水稻小穗中的两个护颖是由侧生小花退化而来。该研究首次揭示了水稻小穗侧生小花的发育调控机制,为通过提高水稻每穗粒数实现增产提供了可能。据论文通讯作者、西南大学农学与生物科技学院何光华教授介绍,水稻产量的构成有“三要素”——亩穗数、每穗
According to reports, our scientists recently confirmed through research that the original “rice flower” (rice spikelet) consists of three small flowers, and two of the rice spikelets are degenerated from lateral florets. This study, for the first time, reveals the regulatory mechanism of spikelet flower growth and development in rice and provides the possibility of increasing grain yield per spike. According to the author of the essay, Professor He Guanghua from Southwest University School of Agronomy and Biotechnology introduced that the composition of rice yield is “three elements” - the number of ears per mu,
