| 摘 要： | 特异株型大豆与普通大豆比较,茎、叶、花的形态有着较大的区别,表现为:茎的中下部为圆形,上部为扁形或棱形;叶片的着生状态既有对生、互生也有轮生,而且多数叶片生长于茎的中上部,叶柄较短;花集中生长于茎的顶端呈现一大荚簇.特异株型结构使大豆在生殖生长时期的源库供应关系较为合理,降低了大豆花荚脱落率.

| Abstract: | The comparion of the special plant-types soybean with the common soybean, showed that there is a bigger difference in the morphology of stem, leaf and the flower. (1) The lower & mid stem is circular, while at the upper part is flat or crista. (2)The leaves grown on stem have three arrangements lumbricine,alternative,cyclic. Most leaves growth in the mid and upper stem. The petiole length is shorter. (3)The inflorescence growth at the top stem and form a big podtuft . The special plant-types make the source-sink relation more reasonable at reproductive growth stages, and decreased the flower and pod abscission rate. |
