两年试验表明,小麦多胚现象是一个可遗传性状。依多胚苗与胚芽鞘关系分为:(1)单鞘双苗型。(2)双鞘双苗型。(3)三鞘三苗型。各类多胚苗在三叶期均能形成各自独立的根系,完成由异养生长到自养生长的转化。从多胚苗的苗期生长发育进程看,可分为。(1)同步型。(2)异步型。但进入三叶期,尤其是成株期后,多胚苗发育进程一致。从成株期各器官体积及结实情况
Two years of experiments show that wheat polyembryony phenomenon is a hereditary trait. The relationship between polyembryonic seedling and coleoptile is divided into: (1) single sheath double seedling type. (2) double sheath double seedling type. (3) Three sheaths three seedling type. All kinds of polyembryonic seedlings in the three-leaf stage can form their own independent root system, to complete the heterotrophic growth to autotrophic growth transformation. From the multi-embryo seedling growth and development process, can be divided into. (1) synchronous type. (2) asynchronous type. But into the trefoil stage, especially after the adult stage, the process of development of polyembryonic seedlings consistent. From the adult organs of the volume and fruiting situation
