Resumo

The objective of this work was to evaluate the interrelations between the climatic attributes, the physiological quality of seeds and the components of soybean yield from different levels of vigor. The experimental design used was the one of blocks at random, where the treatments were composed by DM 5958RSF IPRO®, belonging to the maturation group 5.8 and indeterminate growth habit was used. Before sowing, the seeds were stratified in batches with different levels of vigor. The obtained data were submitted to analysis of variance, later they were submitted to canonical correlation analysis. For the establishment of canonical groups the characters were separated into physiological (group I) and morphological and yield components (Group II). The group of morphological characters: thousand seed mass, germination, accelerated aging, electrical conductivity, viability and vigor, shoot and root length, shoot and root dry mass, field emergence are strongly associated with the yield components of soybean, regardless of the vigor level used. Depending on the level of vigor used, the maximum temperature, minimum temperature, average temperature, relative humidity, soil temperature at five centimeters, soil temperature at ten centimeters, radiation and precipitation influence the soybean yield components differently. From the climatic variables: maximum temperature, minimum temperature, average temperature, relative humidity, soil temperature at five centimeters, soil temperature at ten centimeters, radiation and precipitation, it is possible to predict morphological characters and yield components of soybean.
