Correlação entre testes de vigor e germinação, em sementes de soja, coletadas em propriedades na região do médio norte de Mato Grosso

Abstract

The objective of this study was to evaluate the physiological quality and vigor tests correlate with the germination test and seedling emergence in the field batch of seeds collected in the North East region of Mato Grosso. We evaluated 48 plots of soybeans, totaling 19 cultivars, there was the force test first count and germination test, evaluated the mass of 1000 seeds. The Pearson correlation test for comparison of vigor tests was applied, and was also presented the studentizados waste to comparisons made. It was found that the germination varied between 21 and 94.5% on average overall germination of the 78.65%. As for waste, the results show the presence of outliers in all the comparisons made, and these values are more frequent in plots with low physiological quality. The conclusion is that 37.5% of the surveyed below the minimum requirement for germination (80%) and even batches with more than 80% germination vigor may have problems, and the presence of outliers can affect the results the correlations of force testing with the germination and seedling emergence in the field. The laboratory germination test correlated in a superior manner with the germination and vigor than with seedling emergence in the field.
