简介:Populus种类是为工业并且在生物、农业的系统上的科学学习的重要资源。我们的目的是在喜玛拉雅的白杨提高植物新生的频率(Populusciliata墙。前Royle)。TDZ的效果独自并且在有腺嘌和NAA的联合在叶柄将生物的活组织移植于培养基中培养的新生潜力上被学习。将生物的活组织移植于培养基中培养从在温室种的喜玛拉雅的白杨植物被切除。在表面消毒以后,将生物的活组织移植于培养基中培养在射击正式就职媒介上是有教养的。高百分比射击新生(86?%)在与0.004补充的MS媒介上被记录?mgL1TDZ并且79.7?mgL1腺嘌。为延伸和增加的改革射击被转移到MS?+?0.5?mgL1BAP?+?0.2?mgL1IAA?+?0.3?mgL1GA3。从在vitro开发的射击的根新生在与0.10补充的MS媒介上被观察?mg?L1IBA。喜玛拉雅的白杨小植物能在2以内被生产?在在沙和土壤的无菌的混合物的acclimatization以后的月。我们从P的叶柄将生物的活组织移植于培养基中培养开发了一个高效率植物新生协议。ciliata。
