裂皮病普遍侵染我国栽培的不少柑桔品种,严重者树皮纵向翘裂,树势衰弱,植株矮化,是枳、枳橙、(木黎)檬作砧的主要病害。为了控制其扩散,可用Etrog香橼作指示植物鉴定新引种、新选育良种是否带毒和茎尖脱霉植株是否已脱毒。加快Etrog香橼的繁殖,可提供更多鉴定试材。本文主要报道1986—1987年的试验结果。 Split skin disease generally infects many cultivars of citrus cultivated in our country. In severe cases, bark longitudinal cracking, weak bark, and dwarfing plants are major diseases of trifoliate orange, citrange and lemon. In order to control its spread, Etrog Citron could be used as a new indicator for plant identification, whether the newly-bred elite is poisonous and whether the shoot-tip mildew plants have been detoxified. Accelerate the growth of Etrog Citron, which offers more appraisal materials. This article mainly reports the test results from 1986 to 1987.
