    A cana-de-açúcar vem se destacando como uma cultura de grande importância. O objetivo deste trabalho foi o de avaliar os efeitos de dois maturadores químicos na cultura da cana de açúcar, variedade SP81-3250. O delineamento experimental foi o de blocos casualizados, com parcelas subdivididas, quatro repetições, utilizando-se os seguintes tratamentos principais: Testemunha; Aminolon Maduracion nas doses de 0,7 L de p.c. ha-1; 1,0 L p.c. ha-1; 1,3 L de p.c.ha-1; Ethyl-trinexapac, na dose de 0,8 L de p.c. ha-1. Os tratamentos secundários constituíram-se das épocas de amostragens: aos 10 dias antes da aplicação (-10 d.a.a.) e 11; 46; 71; 100 e 117 diasapós aplicação (d.a.a.). Concluiu-se que os maturadores afetaram diferentemente as características tecnológicas analisadas, observando-se que o ethyl-trinexapac foi o que apresentou melhorcomportamento, seguido do Aminolon na dose de 0,7 L de p.c. ha-1. Em relação às épocas, os melhores resultados ocorreram na 3ª e 4ª época de amostragem, respectivamente aos 46 e 71 dias, após a aplicação.Sugarcane is one of the most important grass crops. This study evaluated the effects of chemical ripeners on the sugarcane varietySP81-3250 in terms of technological quality. The experiment was arranged in randomized blocks with split split-plots. Main treatments were: 1) Control; 2) Aminolon Maduracion, at a rate of 0.7 L of commercial product (c.p.) ha-1; 3) Aminolon Maduracion, at a rate of 1.0 liter of c.p. ha-1; 4) Aminolon Maduracion, at a rate of 1.3 liter of c.p. ha-1; 5) Trinexapacethyl (Moddus), at a rate of 0.8 liter of c.p. ha-1. Secondary treatments were the sampling dates: 10 days before application (- 10 d.a.a.); 11; 46; 71; 100 and 117 d.a.a. (days after application). Ripeners differently affected the technological parameters, and trinexapacethyl showed the best behavior, followed by Aminolon (0.7 L of c.p. ha-1). The best resultswere found at the 3rd and 4th sampling dates, 46 and 71 days after application, respectively
