中文摘要：为探究两种不同类型植物生长调节剂对大豆叶片昼夜同化物生理代谢的影响,以两个大豆品种合丰50和垦丰16为试验材料,于始花期叶面喷施烯效唑(S_(3307))和2-N,N-二乙氨基乙基己酸酯(DTA-6),在鼓粒期的一昼夜内依次选取9∶30、17∶30、21∶30和5∶30(次日)4个时间点,测定功能叶片中蔗糖含量、淀粉含量、淀粉转化率、蔗糖代谢关键酶活性,并于成熟期测产。结果表明:S_(3307)和DTA-6处理均能促进两品种叶片蔗糖和淀粉在白天的积累和夜间的降解,且S_(3307)对两品种叶片蔗糖的调控效果优于DTA-6,DTA-6调控两品种叶片淀粉的作用效果优于S_(3307)。在不同时间点S_(3307)和DTA-6处理均能够提高两品种叶片夜间蔗糖和淀粉转运率。S_(3307)和DTA-6处理能够提高两品种叶片蔗糖合酶和蔗糖磷酸合酶活性,且均在17∶30达最大值;S_(3307)和DTA-6在整个昼夜变化中提高两品种蔗糖转化酶的活性。S_(3307)和DTA-6能够有效调控两品种的单株荚数和单株粒数,提高产量,S_(3307)和DTA-6处理后合丰50产量与对照相比分别增加17.76%和37.67%,垦丰16产量与对照相比分别增加11.34%和32.49%。综上所述,S_(3307)和DTA-6处理均能通过促进叶片昼夜同化物代谢,提高合丰50和垦丰16大豆品种产量。

外文摘要：In order to investigate the effects of two different plant growth regulators on diurnal variation in physiological metabolism of assimilate in soybean leaves and yield, two soybean varieties, Hefeng 50 and Kenfeng 16, were used as experimental materials. The leaves were sprayed with uniconazole(S3307) and 2-N,N-diethylamino ethylcaproate(DTA-6) in the field at early flowering stage, and the control was sprayed with water. Four time points, 9∶30, 17∶30, 21∶30 and 5∶30(the next day), were selected in one day at seed filling stage. The functional leaves of soybean were taken at each treatment, and the contents of sucrose, starch and the activities of key enzymes in sucrose metabolism were determined. Then the yield was determined at maturation stage. The results showed that, both S3307 and DTA-6 could promote the accumulation of sucrose and starch in the leaves of the two cultivars during the day and the degradation at night. Moreover, the effect of S3307 on the regulation of leaf sucrose were better than that of DTA-6, and the effect of DTA-6 on the regulation of leaf starch of the two cultivars were better than that of S3307. At different time points, S3307 and DTA-6 treatments increased the sucrose and starch transport rate in leaves of Hefeng 50 and Kenfeng 16 at night, S3307 and DTA-6 treatments increased the activities of sucrose synthase and sucrose phosphate synthase in leaves of two cultivars and reached the maximum at 17∶30, which was propitious to the synthesis of sucrose during the day. S3307 and DTA-6 increased the activity of sucrose invertase during the day and night, S3307 and DTA-6 could effectively regulate the number of pods per plant and seed per plant, and finally increase the yield. The yield of Hefeng 50 treated with S3307 and DTA-6 increased 17.76% and 37.67% respectively compared with the control, and the yield of Kenfeng16 increased 11.34% and 32.49% respectively compared with the control. It concluded that both S3307 and DTA-6 could increase the yield of Hefeng 50 and Kenfeng 16 soybean varieties by promoting leaf diurnal assimilate metabolism.
