摘　　要：对云南德宏、临沧植胶区云研77-2、云研77-4、RRIM600、PB86和PR107等5个品种橡胶树死皮病调查结果显示:死皮病发病率均表现出随割龄增加而递增的趋势;云研77-4死皮病发病率明显低于云研77-2,PR107死皮病发病率明显低于RRIM600和PB86。An investigation was carried out to study the incidence of tapping panel dryness （TPD） on five rubber clones includ- ing Yunyan77-2, Yunyan77-4, RRIM600, PB86 and PR107 in Dehong and Lincang. The more the tapping years go, the more serious the disease would be. Of all tested clones, the incidence in clone Yunyan 77-4 was obviously lower than that of in clone Yunyan 77-2, and clone PR107 was the lowest compared with the other two clones RRIM600 and PB86.
