Abstract
[Objective] The aim was to explore effects of spraying glyphosate on sugar-nitrogen accumulation in glyphosate-resistant rapeseed so as to provide theoretical basis for the breeding and production of herbicide-resistant rapeseed variety.[Method] We studied effects of spraying glyphosate on sugar-nitrogen accumulation in glyphosate-resistant rapeseed through field experiments.[Result] Spraying glyphosate on glyphosate-resistant rapeseed at bolting stage,soluble sugar content and total amount soluble sugar of various organs obviously increased at the beginning and ending of flower stage and maturing stage;nitrogen content and total amount nitrogen of various organs obviously reduced;the ratio of soluble sugar to N of various organs increased obviously.Under the conditions of N, P, K and no fertilizer application,the above indexes of spraying glyphosate had similar change tendency.[Conclusion] After spraying glyphosate, there is a tendency that various organs sugar increased and nitrogen reduced,which may be mainly due to the decline of the synthesis of nitrogen content matter.关键词
