| 摘 要： | 试验以高淀粉玉米(四单19)、普通玉米(东农250)、优质蛋白玉米(丰禾10号)为材料,研究氮素用量对春玉米籽粒可溶性糖和淀粉积累的影响.结果表明:籽粒中蔗糖含量在吐丝后先增加后降低,果糖和可溶性总糖含量一直呈下降趋势,淀粉含量在籽粒灌浆过程中不断上升.

| Abstract: | This experiment utilized high starch maize Sidan19, common maize Dongnong250 and good quality protein maize Fenghe 10 as materials, the effects of nitrogen application on soluble sugar and starch accumulation in gains of spring maize were studied. The results showed that sucrose content in grains increased firstly and then fell gradually after spinning. The contents of fructose and total soluble sugars fell gradually. The content of starch went up gradually during grain filling stage. |
