| 摘 要： | 柿树(Diospyros kaki L.f.)树干,由于受太阳光直射和温差过大的影响,常发生日灼,局部皮层深裂、脱落,乃至本质部裸露,造成树体衰弱、减产甚至死亡。经初步调查发现,柿树日灼主要发生在黑枣(D.lotus.L.)砧木上,且与砧木高度呈显著的正相关。

| Abstract: | Because of direct exposure to sun light and related high tem-prature, persimmon tree stems are often scorched with the symptoms of deep cortex split, cortex fall off and naked xylem followed by weakening of tree vitality, decreasing of yield and even death. Preliminary investigations reveal that stem scorchings mainely occur on the date-plum persimmon stocks. And the heights of the stocks are positively related to the stem scorchings of persimmon. |
