从广西桂香芒果病果中分离出了芒果蒂腐菌Dothiorelladominicana。对其生物学特性研究的结果表明 ,不同的时间、温度、pH值、光照等条件对该菌的分生孢子萌发、菌丝生长和产孢有显著的影响。在 1 0 0 %RH下 ,3小时后分生孢子开始萌发 ,9小时后达到最高 ;该菌的最适生长温度区是 2 5～ 34℃ ,最适生长pH在 3 5～ 5 5之间。室内药剂测试表明 ,2 5 %施保克乳油对该菌抑制作用较强。
Dothiorella dominicana was isolated from Guangxi cinnamon mango disease fruit. The biological characteristics of the study showed that different time, temperature, pH, light and other conditions on the conidia germination, mycelial growth and sporulation have a significant impact. Conidia started to germinate after 3 hours at 100% RH and reached the highest after 9 hours. The optimum temperature range for growth was 25 ~ 34 ℃ and the optimum growth pH was between 35 and 55 . In-house pharmacy tests showed that 25% Shi Bao Ke EC had strong inhibitory effect on this bacterium.
