利用陆地棉矮化材料,研究植株矮化进程及相关性状表现,结果表明:陆地棉植株高度可以逐步矮化,但需要结合陆地棉植株的产量空间、株型结构、生长势减弱、根系不发达、矮化性状不稳定等因素,因而提出了陆地棉矮化材料“丰产性与株高、矮化形式和稳定性、生长势和根系减弱”等问题与讨论。 Using dwarfing material of G. hirsutum, the dwarfing process and related traits of plants were studied. The results showed that: the plant height of Upland cotton could be gradually dwarfed, but it needs to combine the yield space, the plant type structure, the growth potential of Upland cotton and the underdeveloped roots , Dwarfing instability and other factors, and therefore proposed a Upland fuzz “high yield and plant height, dwarfing form and stability, growth potential and root weakened ” and other issues and discussions.
