摘要
雷林１号桉３３枯梢病病原菌鉴定为ＢｏｔｒｙｏｄｉｐｌｏｄｉａｔｈｅｏｂｒｏｍａｅＰａｔ．（Ｌｉｍｅｔａｌ，１９８５）。病原因菌丝体在温度３０～３３℃生长最好，分生孢子在２９～３１℃萌芽率最高。光照强度在１０００～２０００ｌｘ能迅速大量产生子座形成分生孢子。菌体在ＰＨ６．５生长最佳。相对湿度８１％～９０％最适于菌丝发育。
The pothogen which cause Eucalyptus No. 1 dieback is identified as Botryodiplodia Pat. (Lim et al). The temprature 30-33℃ is favourable for mycelium to grow. The germination rate of conidia is the highest in temprature 29-31℃. Stroma and conidia are formed rapidly in quantity in the light intensity from 1 000 1x to 2 000 1x. pH 6. 5 and 81%￣90% of relative humidity are the most suitable conditions for pothogen to grow.
