摘要
通过观察多个广寄生Taxillus chinensis危害园林树木的实例细节,发现几种不同的寄生状态,初步将其分为分枝型、平行型和缠绕型。分枝型指广寄生枝条从寄主枝条上长出,类似寄主枝条的分枝。平行型指广寄生枝条与寄主枝条平行生长,但会长出吸根插入寄主枝条。缠绕型指广寄生枝条围绕寄主枝条生长。对这3种状态的细节进行了描述,并提供了近距离的图片资料。
Through observation on details of Taxillus chinensis parasitizing on landscape trees, several kinds of parasitic states are found. They are preliminarily divided into branching type, paralleling type and circling type. Branching type means twigs of Taxillus chinensis look like branches of host trees. Paralleling type means twigs of Taxillus chinensis parallel branches of host trees, but it would produce root suckers to penetrate branches of host. Circling type means twigs of Taxillus chinensis circle branch of host again and again. Descriptions of these parasitic states are provided, as well as close range photos.
