从本試驗所得资料,可作如下結論: 1.在大豆各生育时期中,不同部位叶片所輸出的光合产物都有相应的集中部位。幼苗—分枝期,中、上部位叶片光合产物大部分(約50—60％)集中分布于主茎生长点、新生叶和伸长的幼茎,较少部分(約10—14％)分布于下部根系;开花期,上、中部位叶片的光合产物亦有39％集中分布于生长点、新生叶和伸长的幼茎,而少部分(15％)分布于自身叶腋中的花芽;結莢期,上、中和下部位叶片光合产物主要集中分布于自身的豆莢,有局部利用的現象。 2.开花—結莢期,如对叶片进行人为的遮阴时,光合产物的輸出会显著减少。 3.同—叶腋間的花和各个豆莢,由于它們生育时間先后不一,光合产物的分布順序为:大莢>小莢>花。
From the data obtained in this experiment, the following conclusions can be made: 1. During the different growth stages of soybean, photosynthetic products from leaves of different parts have corresponding concentrated parts. Most of the photosynthetic products (about 50-60%) in the seedling-branching stage, middle and upper leaves concentrated on the growth point of the main stem, new leaf and young stem, and the smaller part (about 10-14%) distributed in In the flowering stage, 39% of the photosynthetic products in the upper and middle leaves also concentrated on the growing point, new leaf and elongated young stem, but a few (15%) distributed on the flower bud of their own leaf axils; The leaf photosynthetic products of upper, middle and lower leaves were mainly distributed in their own pods and were used locally. 2 flowering - podding period, such as artificial leaf shade, photosynthetic output will be significantly reduced. 3. With - leaf axillary flowers and each pod, because they have different breeding time, the distribution of photosynthetic products in order: big pods> small pods> flowers.
