INTERRELATIONSHIP OF COMPOUNDS OF SOYBEAN SEEDS PRODUCTION WITH MORPHOLOGIC AND CLIMATOLOGIC ATTRIBUTES
Palavras-chave:Glycine max. (L.), selection of traits of importance, production of seeds.
The study was objective of evidencing the interrelationship between the morphological attributes, productivity, climatological and physiological components of soybean seeds. The experiment was conducted in the crop season of 2013/2014 in Santa Rosa-RS, Tenente Portela – RS, Campos Borges - RS and Sarandi – RS in Rio Grande do Sul, Brazil. The experimental design was a randomized complete blocks, with four cultivation environments x 20 soybean genotypes, arranged in three replicates. The analysis canonicals correlations were based in the establishment of the canonical groups with characters were reunid as physiological (Group I), morphological (Group II), yield components (Group III) and climatological (Group IV). Soybean seed yield is potentiated in plants with larger stature and reproductive units in the main stem. The physiological potential of the seeds is determined by the specific interrelationships of the maximum and minimum air temperature intrinsic to the growing environment. Reduced emphasis on assimilate allocation to the formation of lateral branching of soybeans results in more vigorous seeds.
