病残体处于不同相对湿度（ＲＨ）下存活期不同。浸没水中和处于ＲＨ１００％的存活期不超过１个月，ＲＨ９０％的不超过７个月，ＲＨ７５％的不超过１４个月，ＲＨ６５％的不超过３４个月，在ＲＨ５０％～１０％的存活期可达７７个月，即６年半，病残体上休眠分生孢子和菌丝体复苏生长过程是：休眠孢子培养果一大开始萌发。第５天产生孢子梗及孢子。第１２天未见新孢子产生，成熟孢子开给脱落，菌丝萎缩。第６～９天是产生孢子高峰期，一个孢子可新产生孢子１５个，最多达３６个，一个孢子梗可新生孢子４个，最多达６个。
Sick bodies in different relative humidity (RH) with different survival. Submerged and RH 100% survival for no more than 1 month, RH 90% for no more than 7 months, RH 75% for no more than 14 months, RH 65% for no more than 34 months, RH 50% -10% survival Period of up to 77 months, that is 6 years and a half, the dormant dormant conidia and mycelium resuscitation growth process is: a dormant spore culture fruit germination. On the fifth day, spores and spores were produced. No new spores were found on the 12th day, mature spores were opened and shedding, mycelium atrophy. The first 6 to 9 days is the peak spore generation, a spore can produce spores 15, up to 36, a spore can be 4 spores, up to 6.
