摘要
以国家果树种质沈阳山楂资源圃收集的8个种135份山楂种质资源为试材,采用NaNO2-Al（NO3）3-NaOH比色法,研究山楂属资源总黄酮含量及遗传多样性水平。结果表明：山楂属资源黄酮含量具丰富的变异,变异系数为57.07%,其变幅为0.25%~11.65%,通过山楂属植物叶黄酮类成分比较研究,发现了一些有利用价值的叶用资源。
Taking 135 germplasm resources which belong to 8kinds species come from National Hawthorn Germplasm Nursery of Shenyang as materials,using NaNO2-Al（NO3）3-NaOH colorimetery to research the total flavonoids and the genetic diversity of hawthorn.The results showed that the flavonoid content of hawthorn possesses abundant variation,and the variable coefficient was 57.07%,the variatble amplitude was 0.25%-11.65%.It was found that some valuble leaf resources through comparative study for the flavonoids in hawthorn.
