摘要: 西双版纳的27种桑寄生科植物,危害着野生和栽培的双子叶植物及裸子植物83科263属483种。受害严重的果园植株受害率达76一96%,老式茶园普洱茶60%以上植株受害, 三叶橡胶树50%以上受害,行道庭树及外引栽培植物也受到严重威胁,造成经济上的重大损失.桑寄生植物的危害性与其生物学特性、对环境和树木的适应性及寄生方式有关。树木有抗寄生性,抗性强的树种少感染或不感染寄生,抗姓弱的树种感染多种寄生。桑寄生的幼苗吸器不能侵入光滑、坚硬且具腊质的树皮;树皮产生隔离层除去幼苗及树体内的化学抑制作用,致使桑寄生幼苗不能正常生长发育而完成生命周期。

Abstract: Abstract Plants of Loranthaceae did selectively harm io some plants, specially to partial trees and shrubs of dicotyledon in Xishuangbanna, Yunnan. Liana of dicotyledons and plants of gymnosperms were harmed little. Harmed ferns and monocotyledons have not been found. The harm of Loranthaceae is closely related to their adaptations to trees and environments, their biological features and natural regeneration abilities.
