| 中文摘要: |
| 在大田栽培条件下,以垦农4号大豆为材料,通过叶面喷施植物生长调节剂,比较叶片中蔗糖、转化酶、淀粉、可溶性糖、还原糖和总糖含量及转化酶活性,研究6-苄基腺嘌呤(6-BA)、脱落酸(ABA)对大豆叶片碳代谢相关生理指标的影响。结果表明:6-BA、ABA两处理在喷药后40天均提高了大豆叶片中蔗糖含量,除喷药后40d的取样期内均提高了总糖含量,并且6-BA处理的作用效果为最佳,ABA处理次之。主要表现为,喷药后1050d,6-BA处理在不同程度上提高了转化酶活性,增加了淀粉含量和还原糖含量;而ABA处理则是在喷药后2030d提高了转化酶活性,喷药后3050 d提高还原糖含量。综合分析表明,R1期叶面喷施植物生长调节剂6-BA、ABA调控了大豆叶片中糖分含量和转化酶活性,改善了大豆叶片中碳代谢相关生理指标。 |
| 英文摘要: |
| A soybean (Glycine max) cultivar Kennong 4 was taken as the material to study the influence of spraying
6-Benzylaminopurine (6-BA) and Abscsic acid (ABA) on relevant indicators of soybean carbon metabolism through
comparing the content of sucrose, starch, soluble sugar, reducing sugar, totle sugar and invertase activity in leaves. The results showed: after spraying，6-BA and ABA improved the content of sucrose on 40th day，and total sugar execpt 40th day，in addition the effect of 6-BA was better than ABA. Concretely，invertase activity was increased and the con-tents of starch and reducing sugar were improved with 6- BA treatment from the 10 th to the 50th day after spraying; ABA increased invertase activity from the 20 th to the 30 th day after spraying, and reducing sugar content from the 30 th to the 50 th day after spraying. It indicated through analyzing that, at the timeof R1, 6- BA and ABA can improve the content of sugar and the activity of invertase， and they also regulate nitrogen metabolism related indicators in soybean leaves. |
