茶树寄生性种子植物病害
tea plant diseases caused by parasitic seed plants
茶树寄生性种子植物病害(teap一ant dise·ases eaused by Parasitie seed Plants)由寄生性植物引起，这类寄生性植物缺少叶绿素或器官退化，逐渐失去独立性，消耗寄主植物哟水分和养分，引起寄主植物的生理机能失调.以至死亡。寄生茶树的种子植物有桑寄生科与冤丝子科植物。 桑寄生在局部管理不善的林内或林地附近老茶园可达40%左右，甚至100%，严醒受害茶树树冠几乎全被寄生植物取代，片叶无收。它还能为害数十种植物。在国内主要发生于云南省老茶区，常见的有小红花寄生、卵叶梨果寄生和栗寄生，其次有梢花、离瓣寄生、亮叶木兰寄生和红花寄生。 栗寄生为常绿半寄生亚灌木，叉状分枝.具明显的节，常扁平.相邻的节排列于同一平面.叶对生，退化成鳞片状，基部连生成环，花单性，雌雄同株，小形簇生于叶腋.子房下位，果为浆果，无根。其他几种桑寄生，为常绿半寄生小灌木，叶对生，其上被星状茸毛或无毛，总状，称状或伞形花序腋生，花两性，4一6基数.花瓣离生或合生成管状，开花时顶部开裂，子房下位.果为浆果，无根。桑寄生科植物种子多靠鸟类取食浆果传播，萌发时在条树枝条上形成吸盘.以吸根伸入寄主与木质部愉导组织相连.吸取水份与无机盐类，胚芽向上发育成枝梢。栗寄生在茶树体表无根出条.其他几种桑寄生在茶树体表长根出条.根出条萌生力极强。 范丝子寄生为全寄生的攀缘性藤蔓植物，无根、无叶.只有黄或淡红色的膝茎。花小，白色或淡红色，总状、往状或簇生成头状花序，果为慈果。寄生茶树的为日本冤丝子.茎较粗，种子较大，主要为害木本植物，成熟种子掉落七中.来年萌发.胚芽长出土面形成茎，遇适宜寄主即缠绕其上.产生吸盘，以吸根伸入寄主与导管、筛管相连.吸取嵌主养分和水分，此后冤丝子茎渐与上面中断，膝茎继续生长.获延为害。 防治加强茶园管理，增强茶树抵抗力;寄生植物种子成熟前及时清除，尤其应注众清除桑寄生植物的根出条.减少病原.重病茶树可视树势进行重修剪或台XlJ更新(喻盛甫)
