摘要： In laboratory bioassay, we analyzed the allelochemicals in leaves of ginkgo (Ginkgo biloba) and determined their allelopathic effects on fusarium wilt (Fusarium oxysporum) of hot pepper. The extract of G. biloba leaves inhibited the growth of fungus at 0.04 g l(-1) concentrations, whereas, control was stimulatory. Twenty two types of allelochemicals were identified and 8 (2-Hydroxypropionic acid, benzoic acid, myristic acid, 3-hydroxybenzoic acid, 3,4-dihydroxy cinnamic acid, n-hexadecanoic acid, 8-octadecenoic acid, eicosanoic acid. 2-hydroxypropionic acid) were bioassayed for their allelopathic effects on mycelial growth and spore germination of fusarium wilt. The myristic acid, 9-octadecenoic acid and eicosanoic acid at 200 mu M concentrations, promoted the mycelial growth and spore germination of fusarium wilt. However, 2-hydroxypropionic acid, benzoic acid, 3-hydroxybenzoic acid, 3,4-dihydroxy-cinnamic acid and n-Hexadecanoic acid inhibited the mycelial growth and spore germination of fusarium wilt at this concentration. The allelochemicals differed in effects on fusarium wilt.
