将从培养瓶中移出的冬季(12～1月)或春季(3～4月)的香蕉组培苗置于大棚内，并在4种遮荫水平下进行假植炼苗，相对光强分别为100%(S100)，33%(S33)，10%(S10)，3(S3)的光照条件。结果表明，不同光照强度下，单株香蕉苗的鲜茎重、鲜叶重、鲜根重、总鲜重、干茎重、干叶重、干根重和总干重都存在显著差异，但不同的生物量性状对光照强度的反应程度不同。冬季或春季遮荫均不利于单株香蕉苗的物质生产，且随遮荫程度的加重，影响愈大。同时遮荫还改变物质运输分配到各器官的比例。此外，春季与冬季相比，春季地上部各器官物质积累大于冬季，而冬季地下部根系的物质积累又要大于春季地下部的物质积累。%With four shading levels in winter or spring, banana seedlings obtained by tissue culture were planted in the big shed. The four light treatments were respectively 100%(S100), 33%(S33), 10%(S10) and 3%(S3). Results showed that the effects of banana seedlings at different light intensities were significantly different in fresh stem weight, fresh leaf weight, fresh root weight, total fresh weight, dry stem weight, dry leaf weight, dry root weight and total dry weight. The response of different biomass characters to light intensity was different. Shading in winter or spring was all not propitious to the substance production of banana seedling, and the more the shading was, the more the influence was. The proportion of photosynthate distributed to organs was also changed with light intensity. Moreover, the substance accumulated in aboveground organs in spring was more than that in winter, and the substance accumulated in root in winter was more than that in spring.
