Efeito da aplicação de maturadores químicos na cultura da cana de açúcar (Saccharum spp.) variedade SP81-3250

摘要: Sugarcane is one of the most important grass crops. This study evaluated effects chemical ripeners on sugarcane variety SP81-3250 in terms technological quality. The experiment was arranged randomized blocks with split split-plots. Main treatments were: 1) Control; 2) Aminolon Maduracion, at a rate 0.7 L commercial product (c.p.) ha -1 ; 3) 1.0 liter c.p. 4) 1.3 5) Trinexapac-ethyl (Moddus), 0.8 . Secondary were sampling dates: 10 days before application (- d.a.a.); 11; 46; 71; 100 and 117 d.a.a. (days after application). Ripeners differently affected parameters, trinexapac-ethyl showed best behavior, followed by (0.7 ). results found 3 rd 4 th dates, 46 71 application, respectively
