Avaliação de sementes de trigo submetidas ao tratamento químico associado ao tempo de armazenamento

Abstract

Seed treatment (TS) is a common practice for crops. However, industrial treatment (TSI) or seed on farm may positively or negatively imply seed quality when stored, directly impacting sowing. The scope of the present work was to analyze the impact of TS of wheat on the quality of seeds stored in an uncontrolled environment, submitted to a combination of fungicides, insecticides, micronutrients, polymer and powder-drier. A 5 × 2 factorial design was used in a completely randomized design, with 4 replicates, where 5 treatments were used differing by the time they received the application of the product set. witness; treated; treated and stored; stored; stored and treated, and two seed lots of two cultivars being these TBIO Toruk® and TBIO Sonic®. Being evaluated by the following parameters: germination, accelerated aging and electrical conductivity. Data were submitted to analysis of variance and comparison of means by the Tukey test at 5% by the Sisvar® program. It is possible to show that TS does not interfere in the quality of seeds, being the main factor of loss of quality the storage time.
