番茄叶霉病菌不同菌株粗毒素对种子萌发的影响

Influence of Different Strains′toxicant on Seeds Buding in Fulvia Fulva

番茄叶霉病菌不同菌株产生的糖蛋白毒素粗提物对番茄和茄子种子具有一定的致病性,而对黄瓜作用很小;敏感菌株对种子的萌发抑制率大于抗性菌株,并且抗性水平越高,差别越大;而对于胚芽和胚根,抗性菌株和敏感菌株没有明显的差别,毒素对胚芽的生长抑制率大于对胚根的生长抑制率。

Different strains producing giycoprotein toxin in Fulvia Fulva had some infection on tomato and eggplant seeds,but no nearly function on cucumber seeds.Sensitive strains were greater than resistant strains on seeds germination controlling rates;The higher resistance levels,the greater the difference;there was no difference to radicel and embryo growth of sensitive or resistant strains, the toxicant had more affection on embryo than on radicel.
