摘 要 ：于１９８８－１９９４年对茶赤叶斑病的发生规律进行了研究。室内培养表明，２２，２４，２６，２８℃等４个处理均适宜病原菌的生长发育，离体插枝接种显示，品种间有抗性差异，且以晚间接种发病率高。该病流行程度与５－７月３个月的平均ＲＨ（Ｘ１）呈正相关，与８月份雨日数（Ｘ２）呈负相关，其综合影响的二元回归式为Ｙ＝－３７．３８４２＋０．６４７１Ｘ１－０．７０７９Ｘ２，ｒＹ１．２＝０．８２７４，ｒＹ２．１＝－０．

Abstract:The occurrence pattern of red leaf spot (Phyllosticta theicola Fetch) was investigated in the fields coupled with laboratory simulation. The in vitro culture and inoculation in the laboratories showed that the pathogen was suited to the temperature range
