用不同致病力的棉花枯萎菌（Ｆｔｔｓａｒｉｕｍｏｘｙｓｐｏｒｕｍｆ．ｓｐｖａｓｉｎｆｅｃｔｕｍ）７号和３号小种接种棉花，对抗、感品种根部细胞壁氨基酸含量进行分析。结果表明，感病品种在接种７号小种后，根内细胞壁氨基酸含量增加了３２．３％，抗病品种增加了４，４％；接种３号小种后抗病品种氨基酸含量下降了１４％，感病品种上升了１９．８％。感病品种受枯萎菌诱导后细胞壁氨基酸的积累明显高于抗病品种，为枯萎菌的生长提供了较多的氮源，易与枯萎菌建立寄生关系，认为细胞壁氨基酸含量与棉花对枯萎病的抗性具有一定相关性。
Cotton with different virulence of Fttsariumoxysporumfspasinfectum 7 and 3 was inoculated with cotton to analyze the amino acid content in the root cell wall of susceptible and susceptible varieties. The results showed that after the inoculation of race 7, the amino acid content of the cell wall increased 32.3% and the susceptible variety increased by 4,4%. The amino acid content of resistant varieties decreased by 14% %, Susceptible varieties increased by 19.8%. The accumulation of amino acid in cell wall induced by Fusarium oxysporum was significantly higher than that in resistant cultivars, which provided more nitrogen sources for the growth of Fusarium oxysporum and facilitated the establishment of parasitism with Fusarium wilt. It was concluded that the amino acid content of cell wall was positively correlated with that of cotton on Fusarium wilt Resistance has some relevance.
