摘要
The evaluation of the effect of seed has been fundamental tool in the program of quality control, and the accelerated aging test, an important part of that process. Some authors report that the germination and vigor are associated with seed size and facing the lack of consensus for the use of this test methodology and the relationship of seed size on the physiological quality, this work aimed to adapt the existing methodology as the temperature and period of conditioning on the performance of two sizes of seed cotton. The seeds were classified into two meshes of sieves, and then subjected to tests of water content, germination and electrical conductivity. The experimental design was completely randomized, analyzed statistically in a factorial threefold. Seeds of different sizes, showed no difference in percentage of germination. Seeds subjected to 40 degrees C for 42h of conditioning showed better percentage of germination.
