Abstract
The effect of chitosan- and vanillin-based immune modulators on the development of the phytopathogen Cochliobolus sativus (S. Ito & Kurib.) Drechsler ex Dastur, which induces dark-brown blotch (helminthosporiosis) in wheat, has been studied. It was shown that treatment with these substances led to a decreased injured area in leaves and an increase in the biotrophic period of pathogen development. It was found that vanillin-modified chitosan effectively provided wheat resistance to hemibiotrophic pathogen C. sativus. Changes in leaf peroxidase activity correlated with the manifestation of disease symptoms.
壳聚糖免疫调节剂和香草素免疫调节剂对植物病原菌大黄菌生长发育的影响研究了引起小麦黑褐色斑点病(蠕虫孢子病)的Drechsler ex Dastur。结果表明，用这些物质处理后，叶片损伤面积减少，病原菌发育的生物营养期延长。结果表明，香草素修饰的壳聚糖能有效提高小麦对半营养型病原菌的抗性。叶片过氧化物酶活性的变化与疾病症状的表现相关。
