诱导

The best relative effect of cross-protection was found when spore concentration of Cladosporium cucumerinum was adjusted to 1×10^2 spores/ml for 48 h interval. And it was much better in resistant cultivars than in susceptible ones. Meanwhile, after challenged by Corynespora cassiicola the cucumber induced by Colletotrichum orbiculare produced great resistance to brown-spot, but that increased the development of anthracnose.

在黑星病菌对霜霉病菌的诱导作用中，以浓度为1×10^2个／ml的黑星病菌孢子悬浮液的诱导效果最好，诱导间隔期为48h黄瓜黑星病菌对霜霉病的交互保护作用最明显，抗性品种的交互保护作用明显好于感病品种；炭疽病菌可诱导黄瓜有效抑制褐斑病的发生，但挑战接种褐斑病菌后，却促进了炭疽病的发生。

Lesion numbers on the inducer-treated plants treat with BTH, JZG and TS were significantly less than on control plants, in the meantime, treatment with BTH, JZG and TS led to an increase in activities of chitinase and β-1,3-glucanase in tobacco leaf tissue. Indicated these inducers triggered SAR in tobacco plants; in the same, BTH, JZG and TS were sprayed on the 1st leaf on melon plant before challenge inoculation with Erysiphe cidhoracerum.
