摘要: 通过研究不同浓度的GA3和PP333及两激素不同浓度的互作对萝卜叶面积、叶重量、叶子叶绿素含量及根冠比的影响。结果表明,两者对叶子叶绿素含量没明显影响,但GA3在促进叶子的生长,叶面积的增大上以10~30ppm效果最好,而PP333虽然能抑制叶子的生长,但在肉质根生长中后期试用50ppm浓度的PP333,抑制了叶子的生长,反而促进了光合产物输送到肉质根,起到增产的作用。适当浓度的GA3和PP333及两者结合增产效果明显

Abstract: Radish was used as material for testing the effect of different concentration treatment of GA3 and PP333 on the contents of leaf area, leaf weight, leaf chlorophyll content and root/top ratio. The results showed that GA3 has no effect on the leaf chlorophyll content. 10~30ppm of GA3 had the best effect on leaf growth and leaf area. 50ppm of PP333 used in later stage of root growth can promote transportation of photosynthetic product to the root. Suitable concentration of GA3 and PP333 has a remarkable effect on increasing production.
