- 摘要:
- 为明确夏大豆茎叶生长及其与农艺性状的关系,对47个品种(系)进行了2 a的定株观察试验。结果表明:大豆每长出1片复(真)叶,需3.2 d,积温90.5℃;中熟品种主茎第9片复叶展开前后始花,12~13片复叶展开时结荚;主茎节数与叶片生长期、株高、单株荚数、单株粒数呈正相关,与百粒重呈负相关;叶片生长期与出苗~始花、花荚期、鼓粒期、出苗~始荚、生育期、叶片生长期占生育期比重呈极显著正相关。
- Abstract:
- In order to identify the growth of stem and leaf of summer soybean and its relationship with agronomic characteristics,47 varities(lines) were observed for 2 years.The results showed that the soybean need 3.2 days and90.5℃accumulated temperature to grow one compound(true) leaf;It began to flower when the 9th- compound leaf in main stem expanding for medium mature varities,to pod when the 12ed~13rd compound leaf in main stem expanding;Nodes of main stem was positive with leaf growth period,plant height,pods number per plant and seeds per plant,negative with 100-seed weight;Leaf growth period was extremely positive with seedling~flower stage,flower and podding stage,seed filling stage,seedling~podding stage,growth period,ratio of leaf growth period to growth period.
