| 摘 要： | 试验选用先玉335和军单8两个品种,设70、65、60、50 cm 4个行距水平,研究不同行距种植对春玉米PEP羧化酶活性和产量的影响。研究结果表明:不同处理间产量存在差异,在70 cm和50 cm行距处理下产量显著高于65 cm和60 cm行距处理,70 cm和50 cm行距处理在生育后期穗位叶片保持较高的叶绿素含量和PEP羧化酶活性,促进了个体生长发育,减少了秃尖长度,降低了空秆率。

| Abstract: | Field experiments were conducted to study the effect of different row spacing on PEPCase activity and yield of spring maize.Four levels of 70,65,60,50cm were set in the test,and 'Xianyu 335'(XY335) and ‘Jundan 8’(JD8) were chosen as the maize varieties tested.The results showed that the difference between different treatments was significant.The yield of maize in 70cm and 50cm treatments were higher than other treatments.Chlorophyll content and PEPCase activity in ear leaf was enhanced in later period of growth.The growth and development of single plant was promoted,bare plant rate and the length of barrenness was decreased. |
