Reguladores vegetais e qualidade tecnológica da cana-de-açúcar em meio de safra

Abstract: RESUMOA maturação da cana-de-açúcar (Saccharum officinarum L.) refere-se a um dos aspectos fundamentais para o sistema de produção da indústria sucroalcooleira. Objetivou-se, neste trabalho, avaliar a qualidade tecnológica da cana-de-açúcar em função da aplicação de reguladores vegetais em meio de safra. O delineamento experimental utilizado foi o de blocos casualizados com cinco repetições, sendo os tratamentos constituídos da aplicação de quatro maturadores da classe dos retardantes de crescimento (Ethefon, … Show more

“…The application of glyphosate as a ripener decreased the vegetative growth rate, which was associated with reduced levels of glucose and fructose and, in turn, an increase in the percentage of sucrose. 8,42,43 Bagasse and trash production are determined not only by the genetic characteristics of the variety but also by sugarcane yield and stalk production, which were positively influenced by thiamethoxam use. Bagasse is determined by multiplying the fiber and stalk yields at 50% moisture, while for trash a factor of 140 kg of bagasse per megagrams of stalks is used.…”

“…Therefore, the stalks were obtained at all sites except the late season harvest trial, where the sucrose concentration was slightly lower than 13%. The application of glyphosate as a ripener decreased the vegetative growth rate, which was associated with reduced levels of glucose and fructose and, in turn, an increase in the percentage of sucrose 8,42,43 …”

“…practice changes structural and vital processes by altering the plant hormonal balance, aiming to increase production, improve quality or facilitate harvest (MATEUS et al, 2004). Among growth retardant, trinexapac-ethyl has been recently released in Brazil and studied in wheat (T. aestivum L.) (ESPINDULA et al, 2009b;ESPINDULA et al, 2010b;SOUZA, et al, 2010), rice (Oryza sativa L.) (ALVAREZ et al, 2007), soybean (Glycine max L.) (LINZMEYER JUNIOR et al, 2008), sugarcane (Saccharum sp L.) (LEITE et al, 2008, VIANA et al, 2008, among other crops. This compound is an acyl-cyclohexanedione derivative that inhibits 2-oxoglutarate-dependent dioxygenases in step 3 of gibberellin biosynthesis (SRIVASTAVA, 2002).…”
