Teores de proteína em feijão carioca comum dessecado em diferentes épocas e princípios ativos

Abstract

The objective of this work is to evaluate the protein content of the BRS Esteio black bean cultivar submitted to desiccation with different active principles at different times, correlating these levels with the physiological quality of the same. The work was conducted at the Laboratory of Plant Physiology of the Federal Technological University of Paraná, Campus Pato Branco. Black bean seeds of the cultivar BRS Esteio desiccated with the active principles Diquat, Glyphosate potassium, Glufosinate-ammonium and Saflufenacil were used in four distinct seasons (50, 60, 70 and 80% of mature pods). For total protein determination, the descritive Bradford methodology was used. With these results, the ANOVA correlation test was carried out. The expected problematic is that the desiccated seeds when the plants presented 50 and 60% of the mature pods, present a reduction of the protein contents, as well as, that the desiccants Saflufenacil and Diquat result in the highest levels of protein.
