育成具有早熟大麦熟期的小麦品种,不管育种家如何努力也很难实现。在存在的多种问题中,本研究仍就与小麦和大麦抽穗和成熟有关的生理机能的不同进行分析。第一个试验是用熟期早晚不同的大小麦品种各30个,适时在田间播种,从幼穗分化到成熟每个时期都进行调查,结果是幼穗分化期,大麦明显较早,而拔节期两者的差异几乎识别不出来,但是抽穗期、开花期,小麦比大麦晚,成熟期平均晚10天。而抽 Bred into wheat varieties with mature barley maturity, regardless of how hard breeders hard to achieve. Among the many problems that exist, this study still analyzes the differences in physiological functions associated with heading and maturity of wheat and barley. In the first experiment, 30 varieties of big and small wheat with different ripening dates were used, which were sown in the field in time and were surveyed from young spike differentiation to maturity. The result was that young spike differentiation stage, barley obviously earlier, and jointing The difference between the two is barely identifiable, but at heading and flowering, the wheat is later than the barley and matures on average 10 days later.
