Abstract

Phytotoxicity of 37 isolates of seven species ofFusarium has been studied. Metabolites of tested species exhibited signficantly different phototoxicity towards cereal seedlings. Germination was in greatest extent inhibited by metabolites ofF. subglutinans, in smallest extent by metabolites ofF. tricinctum /respectively 50% and 8%/. The growth rate of wheat seedlings was most strongly retarded by metabolites ofF. crookwellense, metabolites ofF. tricictum inhibited growth in the lowest percentage 57% and 29% respectively.

摘要

已研究了 7 种镰刀菌 37 个分离株的植物毒性。测试种的代谢物对谷物幼苗表现出明显不同的光毒性。代谢物对发芽的抑制程度最大的是禾旋孢腔菌（F. subglutinans），最小的是三隔镰刀菌（F. tricinctum）/分别为 50%和 8%/。小麦幼苗生长速率受弯孢镰刀菌（F. crookwellense）代谢物的抑制作用最强，三隔镰刀菌（F. tricictum）代谢物的抑制作用最弱，分别为 57%和 29%。
