关于早熟小麦的发育特性开展对早熟小麦的发育特性研究,弄清楚早熟小麦品种应具有什么特点,限制小麦早熟的因素是什么,对选育特早熟小麦品种具有一定的意义。首先,小麦的早熟性是各个发育时期长短快慢的综合表现。根据观察,弱冬性的“江东门”、“华东6号”具有拔节、抽穗较早和后期发育快的特点;春性的“台湾小麦”、“云南525”等,拔节、抽穗虽早,但后期发育较长,因而成熟较晚,“2—14”大麦、“立新”元麦生育期短而早熟,一主要是前期短和中期发育快,
On the development characteristics of precocious wheat to carry out research on the development characteristics of precocious wheat, figuring out what precocious wheat varieties should have, restricting the precocious factors of wheat is of great significance for breeding extra precocious wheat varieties. First of all, the precocity of wheat is the overall performance of the length of the various stages of development. According to the observation, the weak winter “Jiangdong Gate”, “East China 6” has the characteristics of jointing, ear early and late development; spring sex “Taiwan wheat”, “Yunnan 525”, jointing, heading is early , But the late development of longer, and thus mature later, “2-14” barley, “Lixin” wheat growth period is short and early maturity, mainly in the early short and medium rapid development,
