茎叶体

由于藓类植物特殊的生物学结构用农杆菌侵染其原丝体或者茎叶体很难实现转化，以原生质体作受体是藓类植物转化的常用途径。

Because of the special biological structure of bryology , it was very difficult to transfer foreign gene into the protonema or gametophyte by Agrobacterium-mediated transformation .

而营养体农业则是以收获茎叶等营养体为目的，营养体的可利用养分产量越高越好，不需要完整生育期，在整个生长期内任何时候都可以收获而获得经济产量。

Therefore , the plants need a whole growing period to produce more seeds in the productive system of traditional agriculture , but the plants have to be harvested at the certain growing stages to gain more economic production in the productive system of vegetative agriculture .
