水稻品种不同,开花的早晚时期也有所不同。日本一个研究小组在美国《国家科学院院刊》(PNAS)上报告说,水稻花期早晚是由负责调节成花素的基因决定的。世界各地栽培的水稻都有适应当地气候的开花时期。日本奈良尖端科学技术研究生院大学的研究人员在2007年就发现了诱导花芽形成的植物激素—成花素。在最新研究中,他们又分析了世界各地 Different varieties of rice, flowering sooner or later period is also different. A research team in Japan reported in the PNAS (United States) that rice is determined sooner or later by the gene responsible for regulating florida. Rice cultivated all over the world has its own flowering period adapted to the local climate. Researchers at the university’s graduate school of advanced science and technology in Nara, Japan, discovered the plant hormone florigen, which induces flower bud formation in 2007. In the latest research, they analyzed the world again
