摘要

背景:E3TM大豆耐2,4- d、草甘膦和氨草甘膦,是为有效治理草甘膦等抗除草剂杂草而开发的。除草剂即使是选择性的,也会对作物代谢造成损害,影响生长发育,干扰种子生理品质。目的:对施用除草剂的E3TM大豆种子进行生理品质评价。方法:田间试验采用随机区组设计,4个重复。试验处理为2,4- d胆碱+草甘膦、2,4- d胆碱+草甘膦+ 2,4- d胺和草铵;6大豆生育期喷施,对照不施。收获后,对种子进行首次萌发计数、加速老化、萌发速度指数、茎和根长、茎和根干质量和电导率测试。结果:用Enlist除草剂(2,4- d胆碱+草甘膦和2,4- d胆碱)以及草甘膦+ 2,4- d胺和草铵膦管理Enlist E3大豆,对大豆的活力、发芽数、加速老化、发芽速度、地上部分和主根长度、地上部分和根干质量、电导率等参数均没有负面影响。结论:这些除草剂可推荐在大豆苗期(6期)使用。

Physiological attributes of Enlist E3™ soybean seed submitted to herbicides application
Background: Enlist E3TM soybean is tolerant to 2,4-D, glyphosate and ammonium-glufosinate and were developed for effective management of herbicide resistant weeds such as glyphosate Herbicides, even being selective, can cause damage to crop metabolism, affect growth and development and interfere with seed physiological quality. Objective: The aim of this research was to evaluate the physiological quality of Enlist E3TM soybean seeds submitted to herbicide application. Methods: The field trial was carried out in a randomized block design with four replications. The treatments tested were 2,4-D choline + glyphosate, 2,4-D choline, glyphosate + 2,4-D amine and ammoniumglufosinate; and control without application, sprayed at V6 soybean growth stage. After harvest, the seeds were submitted to first germination count, accelerated aging, germination speed index, shoot and root length, shoot and root dry mass and electrical conductivity tests. Results: The management of Enlist E3 soybeans with Enlist herbicides (2,4-D choline + glyphosate and 2,4-D choline) as well as glyphosate + 2,4-D amine and glufosinate did not negatively impact soybean parameters such as: vigor, germination count, accelerated aging, germination speed, aerial part and primary root length, aerial part and root dry mass and electrical conductivity. Conclusions: Those herbicides can be recommended to be used on post emergence (V6) of Enlist E3 soybean.
