摘要: 采用菌丝生长速率法测定了马尾松针叶二萜酸对番茄灰霉病菌、油菜菌核病菌、小麦赤霉病菌等3种植物病原菌菌丝生长的影响,并采用盆栽幼苗法测定了马尾松针叶二萜酸对黄瓜白粉病菌的防治效果。结果表明:马尾松针叶二萜酸对番茄灰霉病菌、油菜菌核病菌、小麦赤霉病菌3种植物病原菌菌丝生长都有明显的抑制作用,半数有效浓度(EC50)分别为97.79、14.94和76.39mg/L;马尾松针叶二萜酸对盆栽黄瓜白粉病菌有明显防治效果,EC50为84.07mg/L;马尾松针叶二萜酸对4种植物病原菌的毒力随着药物浓度的升高而增强。

Abstract: The effects of diterpenic acids from pine needles of P.massoniana on the mycelial growth of Botrytis cinear, Sclerotinia sclerotiorum and Fusarium graminearum were studied by the mycelial growth rate method. The pot method was used to investigate its control effects on Sphaerotheca fuliginea. Results showed that diterpenic acids from pine needles of P.massoniana have significant inhibitory activity against the mycelial growth of B.cinerea, S.sclerotiorum and F.graminearum and their EC50 values are 97.79, 14.94 and 76.39mg/L respectively. The control fuction against S.fuliginea was obvious, when the EC50 value is 84.07mg/L. The toxicity against 4 kinds of plant pathogenic fungi was strengthened with the increased concentration of diterpenic acids from pine needls of P.massoniana.

Key words: pine needles, diterpenic acids, plant pathogens, antifungal activity
