Abstract

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.
