The Resistant Mechanism of Cucumber Varieties to Downy Mildew

doi:10.3321/j.issn:1000-7091.1993.01.014

Abstract

Abstract: The experimental results showed that the resistance of cucumber varieties to downy mildew displayed positive correlation with chlorophyll content, sugar content and the catalase activity in the leaves.The inocula-tion results of seedlings showed that the resistant varieties increased 2 bands of peroxidase isozyme, but the susceptible varieties increased only 1 band.

Key words: Cucumber varieties, Downy mildew, Resistant mechanism
