我国科研人员揭示了“稻花”发育调控机制,为提高水稻每穗粒数实现增产提供了可能。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、每穗粒数、千粒重,其中每
China’s scientific research personnel revealed the regulatory mechanism of “rice flower ” development, and it is possible to increase grain yield per hectare of rice. Researchers have recently confirmed through research that the original “rice flower” (rice spikelet) consists of three small flowers, and two of the rice spikelets are degenerated by 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 Prof. He Guanghua from Southwest University College of Agronomy and Biotechnology, the composition of rice yield has “three elements ” - the number of panicles per panicle, the number of grains per panicle, the weight of one thousand kernels,
