- 摘要:
- 以大豆嫩丰18为试材,研究了叶面喷施2-N,N-二乙氨基乙基己酸酯(DTA-6)和烯效唑(S-3307)两种调节剂对大豆叶片、荚皮、籽粒的蔗糖含量及转化酶活性的影响。结果表明:两处理提高了嫩丰18叶片的蔗糖含量,在喷药后35~42 d促进了荚皮蔗糖含量的积累,其中S-3307处理调控效果较好,S-3307处理和DTA-6处理分别在喷药后42,49 d和42,56 d增加了大豆籽粒内的蔗糖含量, S-3307处理在喷药后35~42 d极显著降低了叶片内的转化酶活性,在喷药后49~56 d极显著降低了荚皮中的转化酶活性,两处理在喷药后35~42 d极显著增加了籽粒内的转化酶活性。综合分析表明,两种调节剂均有效地调控了大豆的蔗糖代谢水平,提高了无限结荚习性大豆的产量。
- Abstract:
- A comparative study was conducted on the effect of spraying regulation of 2-N,N-diethylamino ethyl caproate (DTA-6) and uniconazole (S 3307) on the content of sucrose and invertase activity of leaf, pod and grain of soybean (Nenfeng 18). The results indicated the content of leaf sucrose and the accumulation of sucrose content in the pod of Neifeng 18 were promoted after 35-42 days of spraying DTA-6 and S3307.Therefore the treatment of S3307?was more effective, the sucrose content of grain of Nenfeng 18 was increased after 42 and 49 days by spraying S3307and was increased after 42 and 56 days by spraying DTA-6.The invertase activity of leaf of was decreased after 35-42 days of spraying S3307?significantly.The invertase activity of pod decreased after 49-56 days of spraying S3307?significantly and the invertase activity of grain was improved after 35-42 days of spraying S3307?and DTA-6 significantly. It was indicated that the plant growth regulators can improve sucrose metabolism effectively and improve the yield of indeterminate soybean.
