Avaliação de cultivares de algodão submetidas a diferentes testes de vigor

Abstract

In a quality control program, the evaluation of seed viability is essential and necessary for successful production. In the quality control of the producing companies, methods that allow a quick evaluation of the viability of the seeds are of great interest. The objective was to evaluate the efficiency of different vigor tests in the evaluation of the physiological quality of colored cotton seeds (Gossypium hirsutum L.), of the cultivars: BRS Jade and BRS Rubi, the research was carried out at the Soil Laboratory of the Polytechnic School of Campus II – PUC GO, Goiânia–GO. The experimental design used for all tests was completely randomized, using four replications for each treatment (cultivate). According to the analyses, the observed results show that BRS Jade excels in all tests regarding vigor, already in comparison between the performed vigor tests, the best tests to perform are G, TB, CE, EA, and PMS as they obtained the lowest coefficients of variation.
