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.
