【摘要】:本文通過孢子萌發(fā)檢測、平板生長抑制法和果實病害防治試驗,測定了淡紫紫孢菌Purpureocillium lilacinus PL36-1防治儲藏期番茄果實灰霉病的效果。結(jié)果表明,菌株P(guān)L36-1發(fā)酵濾液不僅能夠抑制灰葡萄孢分生孢子萌發(fā)和芽管伸長,而且可以抑制灰葡萄孢菌絲生長。對峙培養(yǎng)的菌株P(guān)L36-1顯著抑制灰葡萄孢的菌絲生長,菌絲生長抑制率可達到74.45%,菌株P(guān)L36-1產(chǎn)生的揮發(fā)性物質(zhì)也對灰葡萄孢菌絲生長有一定的抑制作用。菌株P(guān)L36-1發(fā)酵液處理櫻桃番茄果實后,能有效控制番茄果實灰霉病的發(fā)生,含有2×10~8孢子/m L的發(fā)酵液10 d的防治效果達70.64%。
[Abstract]:In this paper, the effects of Purpureocillium lilacinus PL36-1 on the control of gray mold of tomato fruit during storage period were determined by spore germination test, plate growth inhibition method and fruit disease control test. The fermentation filtrate of strain PL36-1 could not only inhibit the germination of conidia and the elongation of bud tube, but also inhibit the growth of hyphae of grapevine spore. PL36-1, a strain cultured in confrontation, could significantly inhibit the mycelium growth of grapevine spore. The inhibition rate of mycelium growth was 74.45%, and the volatile substances produced by strain PL36-1 could also inhibit the growth of gray grape spore mycelium. After the fermentation broth of strain PL36-1 treated cherry tomato fruit, the occurrence of gray mold of tomato fruit could be effectively controlled. The control effect of fermentation broth containing 2 脳 10 8 spores / mL for 10 days was 70.64.
