Abstract:
By heating drying at 50℃,the moisture content of five species of vegetable seed can reach the level of low moisture or the level of super-dry. The result indicated that except cowpea seeds, which should be controlled between 2 and 4 days by heating drying at 50℃,the rest of vegetable seeds have quite strong resistance for high temperature and low moisture content. After the treatment,seeds vigor is similar to control or even be higher than control, without any harmful symptom. Other study also testified that the germination rates of 10 species of vegetable seeds with heating drying treatment at 50℃ are similar to that of initial stages after storage under 20℃ for 98 months. There is no significant difference between heating drying at 50℃,freeze drying and silica gel drying, thus it proved that this drying method is safe and effective.
