播种用银杏种核常温贮藏技术的研究

Study on the Storage Techniques of Ginkgo Seeds under the Condition of Normal Atmospheric Temperature

对银杏种核采用 8种方式 ,贮藏半年后测定发芽率 ,结果表明 ,2个砂藏处理发芽率最高 (CK) ,其次为质量分数为 0 .0 15的丙酸钙 +质量分数为 0 .0 10的褐藻酸钠混合处理 ,其发芽率高达 75 .6%。综合考虑选定质量分数为 0 .0 15的丙酸钙 +质量分数为 0 .0 10的褐藻酸钠混合处理为最佳贮存方法。该技术方法操作简单、成本低 ,种子贮藏量的多少不会影响发芽率 。

We processed Ginkgo seeds with eight ways and examined germination percentage of seeds after six months' storage. The result showed the germination percentage in sand storage was upmost (Note: when the storage of large amount of seeds in this processing method, the germination percentage was only about 50% due to the influence of humidity gradient.). Secondly, the percentage was 75.6% when the processing way was to use the compound of 1.5% calcium propionic acid and 1% sodium alginic acid. This technique was simples,convenient and low cost, and the amount of storage seeds didn't influenced upon the germination percentage. This way may be applied in production.
