Source-sink relationships of wheat plants obtained by the application of systemic herbicides

Abstract: The objective of this work was to evaluate the potential solute translocation among stems wheat (Triticum aestivum), by application systemic herbicides clethodim and glyphosate. experiments were carried out in greenhouse conditions, using cultivars with contrasting for tillering, during winter 2017 2018 Southern Brazil. Clethodim applied on isolated stems, solutes from first three tillers. Translocation evaluated yield parameters stem ears not treated clethodim. Glyphosate used late assimilation carbon without glyphosate treatment. When primary tillers, reduced only which shows that assimilates targeting main sink, detriment other organs. There a decrease net treatment at visible node stage. anthesis, even more nontreated tillers BRS Parrudo cultivar (low tillering). Well-developed show higher whole plant than poor-developed ones.
