| 摘 要： | 在大田条件下,研究了高油玉米(HE-2)和普通玉米(浚单20号)子粒品质形成及相关酶活性的差异.结果表明,普通玉米子粒的脂肪和蛋白质含量显著低于高油玉米,叶片和子粒中硝酸还原酶(NR)、谷氨酰胺合成酶(GS)、酸性磷酸酯酶(ACP)活性也均低于高油玉米,而普通玉米子粒中转化酶活性和淀粉含量显著高于高油玉米.

| Abstract: | The differences both in formation of grain quality and activity of relative enzymes between high-oil maize(HE-2) and common maize(Xundan 20) were studied during filling-maturing stage under field conditions.The results indicated that oil and protein accumulated fast during the fillingmaturing stage and contents of oil and protein in high-oil maize(HE-2) kernel were higher than those in common maize(Xundan 20).Their relevant physiological and biochemical characteristics were also studied,and the activities of nitrate reductase(NR),glutamine synthetase(GS) in leaves and GS,phosphatidate phosphates in grain of the two cultivars took on the same tendency.The activity of NR decreased all the time from prophase of grain filling stage to mature stage, the activities of NR,GS in leaves and GS,phosphatidate phosphatase in high-oil maize were higher than those in Xundan 20,but the invertase activity and starch content were significantly lower. |
