中文摘要：
果蔬等经济作物生产中的重要病害——灰霉病是由真菌灰霉病菌（Botrytis cinerea Pers.Fr）引起,灰霉病菌的侵染垫是病菌侵染植物所必需的,试验研究了侵染垫的侵入机制。结果表明,灰霉病菌的侵染垫能在再生纤维素膜（玻璃纸）上生长并能降解该膜,然后侵入其中,在聚乙烯膜上不能生长亦不降解该膜。侵染垫在再生纤维素膜上的生长方式和侵入过程同在植物细胞表面完全一致,可见,植物中的纤维素是诱导灰霉病菌侵染垫形成和生长的重要因素。试验结果为进一步探讨灰霉病菌的侵染机制提供了线索。
英文摘要：
Gray mould disease caused by Botrytis cinerea is an important disease in cash crop production. The infection cushion is necessary for Botrytis cinerea penetrating into plants, but the mechanism of infection cushion penetrating into plants should be studied. The results showed that the infection cushion of Botrytis cinerea could grow on cellophane then penetrate into and degrade the cellophane composed of cellulose, but it could not grow on polyethylene membrane. The development and penetration process of Botrytis cinerea infection cushion on cellophane was identical to that on the plant surface. It is indicated that the cellulose in plant played an important role in inducing the development and penetration of Botrytis cinerea dicated cushion and provided clues for explaining pathogenicity of Botrytis cinerea.
