摘要/Abstract

摘要： 采用比较研究法和聚类分析初步研究了紫胶蚧与7种寄主植物无机盐含量关系。结果表明,不同寄主植物之间和是否被紫胶蚧寄生的枝条之间,无机盐含量存在差异,14种枝条的无机盐含量分成4组。7种紫胶蚧寄主植物放虫枝条的无机盐含量经聚类分析可分成7类。寄主植物无机盐含量与紫胶蚧胶被厚、死亡率、怀卵量、个体泌胶量有一定关系,但不是很紧密。紫胶蚧寄生后久树枝条中氮、磷(P₂O₅)、铁都有不同程度的减少,钠元素含量几乎没有发生变化,钾、钙、镁、铜、锌、锰都有不同程度的增加,特别是钙元素含量,放虫枝条中钙元素的含量是未放虫枝条的5.3倍左右。其他寄主植物放虫枝条中都有不同种类元素不同程度地比未放虫枝条含量升高或降低。

Abstract: With comparison and cluster analysis methods,the relationship between mineral salt contents of host trees and Kerria lacca was studied.The results showed that mineral salt contents of 7 different host trees and branches hosted by K.lacca or not were different significantly,which could be divided into 4 groups.Cluster analysis suggested that mineral salt contents of 7 host trees hosted by K.lacca could be divided into 7 kinds.There were some relationships between mineral salt contents of hosted branches and the thickness of raw lac,mortality,fecundity and secretion amount of K.lacca but not significant.Compared with control,the contents of nitrogen,phosphorus(P₂O₅) and iron in host branches of Schleichera oleosa decreased to different degrees,while that of sodium nearly had no change and that of potassium,calcium,magnesium,copper,zinc and manganese increased incoordinately,especially the calcium content,which was 5.3 times as that of the control branch.The mineral salts contents of the other host trees also increased or decreased.
