Caracteres agronômicos e qualidade de sementes de soja com alto e baixo vigor submetidas ao estresse por alagamento

Abstract

The condition of soil waterlogging is considered as one of the main stresses in several ecosystems, unrecognized potential of genetic plants for growth and yield. In addition to the cultivation environment, other factors, such as the proper choice of cultivar and the quality of the seeds to be used, contribute to the establishment and construction of a productive crop. They are established with greater vigor and better conditions are established for development under the best conditions and conditions established, with definition of different conditions. Few studies have tested the susceptibility to waterlogging along the different phenological phases of the crop, analyzing, together, the effect of cultivars and seed vigor, without phytotherapic seed performance. Therefore, this agronomic systems evaluation study was carried out with the quality of soybean solutions targeting the cultivars well, depending on the effort to evaluate the initial soybean cultivars, as a function of the initial effort of the soybean solutions, from different solutions, with soil implementation in different phenological phenotypes of the crop. They were seeds with variations in vigor, cultivated under controlled conditions, of the cultivars NA5909RR, TMG73RG RR09RR and TECIRGA RG6RR. The low study was composed of three factors: four cultivars, two levels of seed vigor (high and vigor), and three cultivation regimes (culture without flooding; cultivation with temporary flooding of 5 days from the V6 stage; and cultivation with temporary delay of 5 days from stage R2). The agronomic characters were determined by estimating the number of seeds per plant, number of seeds per legume, number of seeds per plant, weight of one thousand seeds, plant height, height of productive nodes in the main rush, number of secondary seeds, insertion of the first legume, stem diameter, seed yield per plant, and proximate protein and oil contents. The electrical quality of the plants installed, the measure of the amount of germination tests, increased, the amount of germination equipment increased, the amount of dry matter of field plants, the amount of dry matter of plants to be installed, the amount of plant dry matter. The stress from occasional soil waterlogging on the number of seeds per plant, secondary number of seeds per plant, number of productive branches in the main rush, number of productive branches in the main rush, without seed yield per plant, without theory, and on the quality question physiology. The high vigor of the seeds provides increments in the seed yield per plant, in the mass of a thousand seeds, in the number of nodes in the main rush, in the time of insertion of the first vegetable, and in the oil content of the seeds. The expression, and the intensity of response of vigor, seed quality, attention solutions for the proposed soybean plants, are dependent on vigor.
