- 摘要:
- 在田间条件下 , R 6 期采用铝箔遮光处理 ,对三个早熟大豆材料中 、上部节叶片 、荚 、叶柄进行遮光处理, 研究叶片 ,荚、叶柄对粒重的影响。结果表明 ,叶片遮光节粒重下降幅度为 10.4 %~ 33.3%;叶柄遮光节粒重下降仅为 1 .0%~ 8.9%;荚遮光与叶片遮光粒重降幅相近为 27.3~ 40 .0%。粒数比单粒重对遮光反应更敏感。荚的光合作用主要在鼓粒前期进行 。
- Abstract:
- Under the field condition , three precocious soybean varieties were used, the middle node and up-per node of leaves, pods and petiole were shaded treatments with aluminium foil in order to study the influ-ence of leaves, pods and petiole on soybean seed weight at R 5 (seed formation stage).The result showedthat the shading treatments of leaves decreased seed weight for 10.4 %~ 33.3 %;The petioles decreased 1.0%~ 8.9 %;There was a little difference on shading treatments of Pods and leaves, the pods decreased 27.3%~ 40.0%.The reaction of shading was more sensitiver on soybean number of seed than per pod weightat R 5 .It was important that photosynthesis of pods form per pod seed number of soybean, photosynthesisof pods came into being at early pod-filling stage .It was favourable that photosynthesis of pods was in-creased for high yield on soybean.
