| 摘 要： | 以不同抗病性茄子为试材，即抗病类型Solanum tor、S.sis，耐病类型立原紫茄，感病类型西安绿茄，研究了不同茄子品种抗黄萎病特性，根际微生物结构与黄萎菌数量的变化，茄子根系分泌物对黄萎菌的化感作用，并利用GC-MS对根系分泌物的成分进行了鉴定。结果表明：抗病类型的根系分泌物既可以直接影响黄萎菌的生长、发育，又可以通过调节土壤微生物种群结构间接影响黄萎菌的生长，达到抗病效果。而感病类型则正相反。推断这可能是因为抗病类型根系分泌物中存在醇类、胺类、吡喃类、芴类等特异物质，而感病类型根系分泌物中酮类、酚类、酯类、酚酸类物质种类或含量较高。

| Abstract: | Verticillium Wilt is one of the most destructive deceases of eggplant in China.Up to now,the allelochemicals from eggplant root exudates have been found in relation to the outbreak of Verticillium Wilt.However,the relationship between root exudates from different eggplant cultivars and their resistance to Verticillium Wilt has not been determined.Four eggplant cultivars were inoculated with Verticillium Wilt(Verticillium dahliae Kleb.) to assess their resistance to Verticillium Wilt in the present study.The... |
