The soybean has a wide variety of use, whether in the food industry, in the chemical industry, in the production of biodiesel, or with soybean meal, which is used for the composition of animal feed, feeding pigs, poultry and cattle. Several factors influence the quality of soybean seeds, whether biotic and \/ or abiotic stresses, such as high and dry temperatures, for example. These factors can induce premature plant maturation, and therefore produce greenish-colored seeds, which directly affect the physiological quality of soybean seed lots (ARRUDA et al<\/em>., 2016; ZORATO et al<\/em>., 2007). Observing this, researchers from the Federal University of Pelotas (UFPel) and the University of Passo Fundo (UPF) evaluated the influence of the presence of green soybean seeds on their physiological quality in the article \u201cGreen soybean seeds: effect on physiological quality\u201d published in Ci\u00eancia Rural <\/em>(vol. 50, no. 2).<\/p>\n

For the research, six lots of soybean seeds from Cultivar (5958RSF IPRO) with 0, 0, 7, 8, 16 and 18% greenish seeds were used. The researchers carried out tests of first germination count, germination, electrical conductivity, field emergence, accelerated aging, emergence speed index, tetrazolium, length, dry mass and seedling growth curve. After the evaluations, it was found that the greenish seeds have less viability and vigor due to greater deterioration, as the non-degraded chlorophyll reduces the physiological quality of soybean seeds.<\/p>\n

Through graphs and tables, the research elucidated that the physiological changes caused still in the field, are reflected from the seedling phase to the adult phase (vegetative and reproductive), causing visual and economic differences in the crop.<\/p>\n

For the researcher Joseano Graciliano da Silva, “if the number of greenish seeds in the batch is quantified and it is observed that more than 9% of the batch has greenish seeds, it should be discarded as seeds, that is, it should not be marketed.” The companies in the sector must pay attention to the maximum levels of greenish seeds in the lot, avoiding that they are commercialized, causing losses of productivity for the farmer.<\/p>\n
