大豆种子超干燥保存研究 Ⅲ. 25℃、5℃条件下保存一年后种子生活力和活力的变化

摘要

将中豆24和泰兴黑豆种子用无水CaCl2分别干燥至10个不同的含水量水平，密封于玻璃瓶中分别在25℃培养间、5℃冰箱中保存一年后，对种子生活力和活力进行测定。结果表明，中豆24在25℃、5℃条件下保存的最佳含水量为6.0%；泰兴黑豆在25℃条件下保存的最佳含水量为5.4%，在5℃下保存的最佳含水量为6.0%。%In order to further explore the effects of ultra-dry storageprotein-riched seeds, soybean seeds of Zhongdou No.24 and Taixing Heidou were dried to ten different moisture contents using CaCl2, then sealed and stored at 25℃ and 5℃ for one year respectively. Changes of viability and vigour of the stored seeds had been monitored. The results showed that Zhongdou No.24 and Taixing Heidou were suitable for ultra-dry storage and the optimum moisture contents obtained at 50℃, 25℃ and 5℃ were different. The optimum moisture content of seeds of Zhongdou No.24 at 25℃ and 5℃ was 6.0%. The optimum moisture content of seeds of Taixing Heidou at 25℃ was 5.4%; at 5℃ was 6.0%.
