| 摘 要： | 对陆地棉7个野生种系的220份材料进行黄萎病菌的抗性筛选，用8份不同抗性材料进行了根系分泌物分析。从220份材料中筛选出18份抗黄萎病材料。根系分泌物研究表明，抗病品种根系分泌物对黄萎病菌菌丝生长及孢子萌发均具有抑制作用，而感病品种根系分泌物对其则有促进作用。另外通过对根系分泌物中氨基酸和可溶性糖的分析发现，抗病品种根系分泌物中氨基酸种类少于感病品种，并且抗病品种根系分泌物中氨基酸总量和可溶性糖含量显著少于感病品种。同时发现，精氨酸为抗病品种特有氨基酸。

| Abstract: | In present study,18 accessions which were resistant or tolerant to Verticillium wilt were screened out from 220 accessions of all seven races of Gossypium hirsutum.Eight accessions were chosen to analyze the effects of their root exudates on the wilt pathogen,from which four are resistant and four are susceptible,respectively.Higher resistant accessions and resistant ones which are valuable should be found.The resistance mechanism of Gossypium hirsutum can be known partly.Screening on Verticillium wilt resi... |
