实葶葱种子发育过程中物质含量变化规律的研究

Study on the Change of Substance Content in Seed Development Process of Allium galanthum

为了合理开发利用实葶葱资源,以实葶葱种子为试验材料,在实葶葱盛花期进行标记,当花后15~50d统一采收,分别包装,测定不同发育阶段种子的含水量及贮藏物质含量变化规律。结果表明：种子含水量均随发育天数的增加呈下降趋势,下降到0.750%;可溶性糖含量发育过程中变化不稳定;淀粉及脂肪含量均上升,40~50d脂肪含量变化趋势与淀粉含量变化趋势正好相反,且45d之后急剧下降;可溶性蛋白质含量呈先降后升的趋势;随发育时间的延长粗纤维素含量上升,且50d处达到最高。

In order to reasonable development and utilization of Allium galanthumresources,Allium galanthum seeds were selected as experimental material marking.in Allium galanthumflowering and unified gathering the seeds after 15~50dflowering,respectively packing,water content and storagesubstance content were measured at different developmental stages of seed.The results showed that the seed moisture content were decreased as the increasing of growing days,down to 0.750%,the change of soluble sugar content in the process of growing was not stable;starch and fat content increased,the changes trend of fat content and starch content was just the opposite between 40 ~ 50 dand sharp decline after 45days;soluble protein content was descend first and then ascend trend;with the developmental time extend,the crude fiber content increased,and reached the highest at 50 d.
