Conteúdo: | Moisture interchange was investigated in blends os soybean having different moisture content. The blends were sealed in polythylene bags and held at 10 C and in open storage (+- 30 C). In a second experiments, the blends were held in open storage (+- 15 C) but kept in multiwall-paper and sealed polyethylene bags. Responses of the blends to these variables were evaluated in terms of moisture content of each of the blend after various intervals of storage as well standard germination and tetrazolium germination potential for seed quality. To facility separation of the seeds, one portion was dyed and the other left undyed. Separation was accomplished by hand and during this process the seeds were exposed to ambient conditions no more than five minutes. Each blendwas composed of different proportions of "dry" and "wet" seed, however, the average moisture content was 12%. Two kilograms of blended seed were used in each bag. The higher tempearture prevalent in the warehouse during the summer was responsible for more rapid equilibration of moisture content. In all of the blends, a rapid interchange of mositure between the dry and moist component accurred, but exact equalization of moisture content was not obtained due to the hysteresis effect. Most of the change occurred two days following packaging. Subsequent change aoccured at a slower rate with equilibrium being attained from 4 to 40 days depending on storage  tempearture and type of packaging. Equilibrium was considered  to have been attained when there were no (...)
