【摘要】 从番茄植物组织内分离到一株对番茄灰霉病菌(Botrytis cinerea)有拮抗作用的放线菌株No.37,此菌株产生的抗菌物质能显著抑制番茄灰霉病菌的菌丝生长和孢子萌发,对盆栽番茄幼苗的预防保护作用和治疗作用分别达到89.7%和80.3%,10倍稀释液的田间防治效果达到84.1%。更多还原

【Abstract】 Endophytic actionmycetes No.37 was isolated from surface-sterilized tomato plant tissues.It had strong antifungal activity to Botrytis cinerea and other plant pathogens.The metabo-lic products of strain No.37 could strongly inhibit the mycelium growth and spore germination of Botrytis cinerea.The protective efficacy and therapeutic efficacy against Botrytis cinerea on pot tomato plants got to 89.7% and 80.3%,respectively.The effect of 10 times dilution against Botrytis cinerea was 84.1% in the field.更多还原
