新疆陆地棉矮化材料的问题分析

Questions Analysis of Dwarf Materials of Upland Cotton in Xinjiang Province

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。

The Paper studied dwarfing process and related performance by using the upland cotton dwarf materials. Re- suits showed that： the plant height of upland cotton could be gradually dwarf, but required a combination of yield space, plant type structure, weaker growth, root was not developed, dwarfing traits instability and other factors, thus discussed material ＂ high yield and the plant height, the dwarf form and stability, growth and root decreased＂ and so on.
