摘要: 采用体外抑菌活性和盆栽试验测定方法,研究了白黄链霉菌TD-1发酵液对番茄灰霉病菌的抑制效果及植株体内防御酶活性的影响,旨在为番茄灰霉病的生物防治提供参考。结果表明:TD-1菌株发酵液对灰霉病菌的菌丝生长和孢子萌发抑制率分别为98.1%和98.3%;TD-1发酵液在番茄植株上对灰霉病的防治效果为76.98%。喷洒TD-1发酵液24 h后接种灰霉菌孢子悬浮液,番茄叶片中苯丙氨酸解氨酶(PAL)、多酚氧化酶(PPO)、过氧化物酶(POD)和超氧化物歧化酶(SOD)的活力均有所提高,分别在处理后第4,3,2,3 天达到最高。

Abstract: The inhibitory effect of Streptomyces alboflavus TD-1 against Botrytis cinerea and its effect on defensive enzymes activity in vitro antibacteral activity and pot experiment were studied in order to provide reference for biological control of grey mould.The results showed that inhibition rate of fermentation broth of the strain TD-1 on mycelium growth and spore germination of B.cinerea were 98.1% and 98.3% respectively.The control efficiency of TD-1 fermentation broth against B.cinerea in tomato plants was 76.98% in pot experiment.The activity of PAL, PPO, POD and SOD of tomato leaves increased after spraying fermentation broth of the strain TD-1 and spore suspension of B.cinerea.They reached maximum in the fourth day, the third day, the second day and the third day respectively.

Key words: Streptomyces alboflavus TD-1, Botrytis cinerea, Defensive enzymes, Biological control
