摘要
对番木瓜果腐镰刀病菌的生物学特性及其室内毒力进行了测定。结果表明，该病原菌最合适生长温度范围为25～30℃：在中性或偏碱性条件下．有利于菌丝体的生长，而偏酸性条件则对菌丝体生长存在明显的抑制作用；光照对菌丝体的生长影响不大。该菌在以麦芽糖、葡萄糖、蔗糖、D-甘露糖为碳源的培养上生长良好；而在以硝酸钠、L-组氨酸、甘氨酸为氮源的培养基上生长较好。在供试的9种药剂各浓度中，多菌灵、甲基托布津、咪酰胺、戊唑醇以及百菌清5种药剂对菌丝体生长的抑制效果较为显著。
In the present study, some biological characteristics and the virulence indoor of the pathogen of papaya fruit rot were studied. The main results are described as follows： Mycelium growth of the most appropriate temperature were 25-30℃.The conditions of alkaline or neutral were helpful to the growth of mycelium, while light almost didn＇t influence on the growth of mycelium. Maltose, glucose,sugar and D-mannose were all benefical to the mycelimn growth,while sodium nitrite,L-histidine and glycine were also conducive to mycelium growth. In the other hand, the virulence indoor of the pathogen of papaya fruit rot were tested toxicity by the 9 fungicides indoor. The result showed that the Carbendazim, MeroifTM, Prochloraz, Tebueonazole, and Chlorothatonil were the better than other fungicides in all fungicides supplied.
