摘要
1989~1996年对浙江黄岩本地早及其变株新本1号感染柑桔病毒类病害的情况进行了研究。结果表明,这两个优良品种已发现感染了衰退病、碎叶病、脉突病和裂皮病。这些病害一般为复合感染,裂皮病为隐症感染。衰退病和碎叶病发生相当普遍,脉突病发生率也比较高,裂皮病只在部分本地早植株上发生。调查研究发现,衰退病的苗黄株系或强茎陷点株系和碎叶病毒的混合感染,是造成黄岩本地早和新本1号产量低下的一个重要原因。墨西哥来檬叶脉凸起的症状易受到衰退病严重症状的掩盖。同样,脉突病对衰退病有一定的交叉保护作用。
The infection of citrus virus and viroid diseases on Bendizao and its mutant new Ben No.1 was studied in Huangyan,Zhejiang during 1989~1996.The result showed that the two citrus cultivars had been infected with tristeza,tatter leaf,vein enation and excortis diseases mixedly,and the trees infected with excortis viroid didn't show any symptom.Tristeza and tatter leaf diseases were very widespread,vein enation disease was also quite prevalent,but excortis disease was only discovered in some Bendizao trees.One of the important reasons of low yield of the two citrus cultivars was that they had been infected with tristeza (seedling yellow strains or severe stem pitting strains) and tatter leaf virus mixedly.The symptom of vein enation of Mexcian lemon was easy to be covered with the serious symptom of tristeza disease.Vein enation had some cross protection against tristeza.
