灰霉菌及其胞外大分子对不同植物的伤害鉴定

[目的]探究灰霉菌及其胞外大分子毒素对不同植物的伤害情况。[方法]以灰霉菌分生孢子及其分泌的胞外大分子毒素为试验材料,选取21科29属30种植物为供试植物,观察了灰霉菌对其侵染性以及灰霉菌分泌至培养液中的大分子毒素对其伤害情况。[结果]30种供试植物中既被灰霉菌侵染又被毒素损害的植物有17种,占全部植物的56.7%;有2种植物均不能被灰霉菌侵染也不能被毒素伤害。[结论]为进一步了解植物病原真菌毒素致病机制提供了借鉴。

Damage Identification of Botrytis cinerea and its Extracellular Macromolecular on Different Plants

[Objective] The paper was to explore damage status of Botrytis cinerea and its extracellular macromolecular toxins on different plants.[Method] With Botrytis cinerea and its extracellular macromolecular toxins as the test materials and 30 speices of plants belonging to 29 genera and 21 families as the test plants,the infectivity of B.cinerea and damage status of macromolecular toxins secreted by B.cinerea on plants were observed in the paper.[Result]Seventeen species of plants were both infected by B.cinerea and damaged by toxins,accounting for 56.7% of total plants.Two species of plants could neither be infected by B.cinerea nor be damaged by toxins.[Conclusion] The paper provides the reference for further understanding of pathogenic mechanism of plant pathogenic fungi toxins.
