缺磷胁迫下41%草甘膦异丙铵盐水剂对抗草甘膦大豆农艺性状和生理指标的影响
【目的】探明缺磷胁迫下草甘膦对抗草甘膦大豆农艺性状和生理指标的影响,为缺磷条件下抗草甘膦大豆种植时合理使用草甘膦提供理论依据。【方法】以转基因抗草甘膦大豆RR1为材料,采用溶液培养法,在RR1长出真叶时进行缺磷胁迫,第二复叶完全展开时进行4.98 m L/L的41%草甘膦异丙铵盐水剂处理,5 d后测定各生理指标,10 d后测量农艺性状。【结果】正常供磷条件下,草甘膦处理会降低RR1大豆的叶面积、总根长、主根长、地上鲜重、根鲜重、根冠比、根系活力、根系磷含量和叶片磷含量,而株高、叶片SOD活性和MDA含量增加,但与清水处理差异均不显著（P〉0.05）。缺磷胁迫下草甘膦处理的RR1大豆的叶面积、总...

| Notes | 45-1381/S phosphorus deficiency stress ; glyphosate-resistant soybean ; glyphosate ; agronomic character; physiological index [Objective]The effects of glyphosate on agronomic characters and physiological indexes of glyphosate-resistant soybean seedlings under phosphorus deficiency stress were ascertained to provide theoretical references for the rational use of glyphosate in glyphosate-resistant soybean field under phosphorus deficiency stress. [Method]The glyphosateresistant soybean RR1 was used as the research objective and the solution culture experiment under phosphorus deficiency stress at the true leaf stage was conducted. Glyphosate at 4.98 mL/L was sprayed at the two-trifoliolate leaf stage. Physiological indexes were analyzed 5 days after the glyphosate spraying, and agronomic characters were measured 10 days later. [Result]In normal phosphorus condition, glyphosate decreased the leaf areas, total root length, taproot length, shoot fresh weight, root fresh weight, ratio of root/shoot, and phosphorus c |
