| 摘 要： | 根据过去观察,棉籽壳有明显抑制黄萎病菌的作用。本试验初步证明这一抑菌物质具有丹宁类物质的某些特性。不同铃龄各部位的抑菌强度总趋势,与用高锰酸钾滴定法测得的丹宁类物质含量趋势一致,即不论大、中、小铃,感病及抗病品种,种壳的抑菌作用均大于胎座。初步认为种壳中较高浓度的丹宁类物质是种子内部带菌率极低的主要原因之一。纯丹宁在棉籽饼粉酒精洋莱培养基中的抑菌作用较供试的其它培养基小,说明此培养基用于种子带菌分离的优越性。棉花枯萎病菌对丹宁的耐受力显著高于黄萎病菌。

| Abstract: | It was constantly observed in the isolation processes that the cotton seed coat was capable of inhibiting the growth of Verticillium on the medium,The tendency of inhibiting intensity of separate parts of different boll age was very similar to that of the contents of the tannin-like substances titrated with potassium permanganate,Regardless of the boll ages and the susceptibility and resistance of varieties to the fungus,the inhibiting effect of the seed coat was always greater than that of the placenta.So it was thought that the higher concentration of the tannin-like substances in the cotton seed coat was one of the main causes for the very low percentage of interior seed borne Verticillium in cotton seeds.The inhibiting effect of the pure tannin added to the cotton seed cake meal agar medium for Verticillium is lower than that added to other media.This again indicated that the cotton seed cake meal agar medium has the advantage of getting the indication of the seed borne Verticillium fungus.The causal organism of cotton Fusarium wilt has a higher endurance to the inhibiting effect of tannin-like substances than Verticillium. |
