前人研究认为最适宜长期贮藏种子含水量是相对湿度15%条件下种子达到平衡水分,通常禾谷类作物是5～7%,认为种子过分干燥会影响细胞内蛋白质、脂肪类物质的结构和功能,如果含水量低于4～5%则变质比含水量5～6%的种子要快,随着科学技术的发展,近年来国际上开展了种子超干(种子水分<5%)的研究。据报道,Ellis等把芝麻种子水分从5%降到2%,寿命可提高40倍,而贮藏温度从20℃降到零下20℃,寿命提高也只有40倍,可见采用2%超低水分,制冷费用可以降低,其它作物也有类似情况。因此国际
Previous studies suggest that the most suitable long-term storage of seed moisture content is 15% relative humidity under the conditions of seed to achieve equilibrium moisture, usually cereal crops is 5 to 7%, that the excessive drying of seeds will affect the structure and function of intracellular proteins, fatty substances If the water content is less than 4% to 5%, the seeds will deteriorate more than the 5% to 6% moisture content. With the development of science and technology, the ultra-dry seeds (<5%) have been developed in the world in recent years. According to reports, Ellis and other sesame seed moisture from 5% to 2%, life expectancy can be increased 40 times, and storage temperature from 20 ℃ to minus 20 ℃, life expectancy increased by only 40 times, we can see the use of 2% Cooling costs can be reduced, other crops have a similar situation. So international
