大豆籽粒是生殖生长时期植株光合产物主要存储库,鼓粒灌浆期籽粒的生长发育以及干物质积累的过程直接影响大豆的产量。因此,研究大豆籽粒的生长发育及其影响因素对提高产量至关重要。影响大豆籽粒生长发育的因素很多,从源库的改变、外界温度、光照、水分供应以及二氧化碳的浓度的影响,酶活性、内源物质含量的调节以及植物激素的调控等方面予以综述。参64。
Soybean grain is the main storage plant of photosynthate in the reproductive growth period. The growth and development of grain and the accumulation of dry matter during the grain filling stage directly affect the yield of soybean. Therefore, the study of the growth and development of soybean grain and its influencing factors are crucial to increase the yield. There are many factors that influence the growth and development of soybean grains. The changes of source sinks, external temperature, light, water supply and carbon dioxide concentration, enzyme activity, the regulation of endogenous substances and the regulation of plant hormones are reviewed.
