| 摘 要： | 以鲁豆11号为试验材料,利用植物生长调节剂SHK-6拌种和分枝期叶面喷施,在大田条件下研究了大豆根系对物质吸收和合成能力的变化及SHK-6调控的效应.结果表明,SHK-6处理显著提高了根系还原能力和伤流量,显著促进了根系对硝态氮吸收和氨基酸合成与转化;SHK-6显著提高伤流液中各个生育期内IAA、GAs和CTKs含量,而ABA含量前期SHK-6处理是显著低于对照,生育后期显著促进了ABA的运输量;SHK-6显著提高了产量,改善了产量构成因素.

| Abstract: | Field experiments were conducted in 2000 at the research center of china agricultural university to examine the effect of PGR SHK-6 on the change of endogenous hormones and nutrition in bleeding sap of soybean(Ludou 11,cv.).Sequential application of SHK-6 was used for all experiments.Seeds were treated with SHK-6 at 0.4ml/kg seeds and plants were sprayed at branching stage with a dose of 75ml/ha.The results showed that SHK-6 significantly increased root physiological activity,and the volume of bleeding sap.Furthermore,the flow capacity of nitrite and amino acids in bleeding sap were significantly promoted by SHK-6.During whole growth period,SHK-6 significantly promoted the flow capacity of IAA(auxin),GAs(gibberellin) and CTKs(cytokinins) in bleeding sap,but markedly decreased the flow capacity of ABA at period growth stages and notably increased the flow capacity of ABA(abscisic acid) at later growth stages.SHK-6 significantly increased the yield and improved the yield components. |
