Aplicação exógena de ácido salicílico com caracterização agronômicas e físico-químicas de couve folhas minimamente processadas

Abstract

Cabbage has become increasingly important both for farmers and consumers, this greater demand is precisely due to the search for healthy food and even during its production process does not compromise the environment. In this search, alternative products in cultivation are important, among them salicylic acid, which is an elicitor and can be considered an alternative in reducing the use of pesticides in the cabbage crop. In this sense, the objective of this work was to verify the effects of salicylic acid application on plant growth and on the physical-chemical characteristics of leaf kale. The experimental design was completely randomized, with five concentrations of salicylic acid 0 (zero), 0.5; 1.0; 1.5 and 2.0 mM, which were applied biweekly on the leaves, from the transplanting of the seedlings. The exogenous application of salicylic acid promoted physiological changes in plants and physicochemical changes in cabbage leaves.
