Allelopathic effects of diisobutyl adipate on pepper seed germination and Fusarium oxysporum f. sp. vasinfectum
摘要
Abstract
By the methods of laboratory incubation and bioassay, a simulation test was conducted to study the allelopathic effects of different concentration diisobutyl adipate on pepper seed germi-nation and its seedling growth and Fusarium oxysporum f. sp. vasinfectum. For the pepper seed germination and seedling growth, diisobutyl adipate exhibited allelopathic promotion at low con-centration, but allelopathic inhibition at high concentration. There existed greater differences in the allelopathic effects of diisobutyl adipate on the seed germination and seedling growth of pepper and eggplant. The promotion effects of low concentration diisobutyl adipate on pepper were stron-ger than those on eggplant, while the inhibition effects of high concentration diisobutyl adipate on pepper were weaker than those on eggplant. All test concentration diisobutyl adipate had signifi-cant inhibition effects on the mycelium growth of Fusarium oxysporum f. sp. vasinfectum, and the effects increased with increasing diisobutyl adipate concentration, being the strongest (an inhibi-tory rate of 10. 75%) at 1 mnol·L~(-1). Field text indicated that diisobutyl adipate at all test con-centrations enhanced the disease resistance of pepper seedlings. The best effect was observed at 1 mmol·L~(-1) of diisobutyl adipate, with the disease index decreased by 49.88%, compared to the control.关键词
