【摘要】 研究了同源的抗枯萎病品种西农87岱16抗和感枯萎病品种原岱16棉花种子的生化成分及其性质差异。结果表明,抗病性不同的两类品种的种子球蛋白的种类,不同分子量球蛋白的合成比率及次生代谢物棉紫素的含量都有较大变化。本项研究结果支持定向培育法是一种科学的棉花抗病育种方法。更多还原

【Abstract】 This paper deals with the biochemical constituents and characteristic differences in cotton seeds between Fusarium wilt resistant variety——NWAU 87 DPL16 (R) and Fusarium wilt resistant and susceptible variety——Ori. DPL16(S). of the same origins. The results showed that there were great changes in cotton seed globulin and synthetic ratio in globulin of different meleeulars as well as gossypurpurin contents of secondary metabolic products of two kinds of cotton varieties with different resistances. The results of this research project can support the direction breeding method which is a kind of scientific cotton disease resistant method.更多还原
