| Popis: | This work aimed to evaluate the initial development of soybean and maize plants due to the vigor level and the seed size used. Soybean seeds of cultivar 5855 RSF IPRO (BMX ELITE) and hybrid maize Fórmula Viptera were classified in two sizes of sieve (6.00 and 6.50 mm - soybean; 7.50 and 7.00 mm - maize) and two levels of vigor for soybean and three levels of vigor for maize. The experimental design was completely randomized in a 2 x 2 bifactorial scheme (sieve size x vigor levels) for soybean and 2 x 3 (sieve size x vigor levels) for maize, with four replications. The variables evaluated were germination, first germination count and emergence in bed. In the evaluation of seedling initial performance, shoot, root and total length, volume and dry mass were evaluated at 7, 11 and 14 days after sowing for soybean and at 7, 14 and 21 days for maize seeds. High vigor soybean and maize seeds presented high physiological quality, as well as in the development of plants, where larger and of high vigor soybean seeds showed higher plant length and dry mass. The classification of seeds through the level of vigor influences the physiological quality of soybean and maize seeds. Larger seeds with higher vigor showed greater length and initial development of seedlings, being indicated the use of seeds of something vigor |
