But changing range of PAL activity or content of total phenolate and flavoniods between healthy spikes and infected spikes were related negatively to scab-resistance.

材料抗赤性强弱与接种穗与健康穗之间的PAL活性及总酚、类黄酮含量的增加幅度呈负相关。

The dynamic changes of physiological and biochemical indexes of healthy spikes and inoculation ones of the resistant mutants indicated that PAL activity and content and changing tendency of total phenolate and flavoniods and MDA in the healthy spikes of the mutants were similar to that of their susceptible donors, whereas, for the inoculated spikes, content and changing range of these indexes existed significant difference between two kinds of strains, changing from high-resistant variety (Sumai3 ) to their susceptible donors.

以典型抗扩展品种和突变体供体亲本为抗、感对照，对抗赤霉突变体的健康穗及接种穗的生理生化特性研究结果显示，在健康穗中，抗性突变体的PAL活性、总酚、类黄酮及MDA含量及变化趋势与其感病亲本相一致，但在病原菌侵染后，这些生理生化物质的含量与变化程度与其亲本有了明显的差异，其变化范围介于典型高抗品种和感病亲本之间，变化趋势与亲本或抗性品种一致。

The result also showed that, compared with high-resistant variety PAL activity and content of total phenolate and flavoniods in the inoculated spikes of the mutants and their susceptible donors were increased significantly, which were also different within the healthy or inoculated spikes of different genotypes, yet, there was no relationship between scab-resistance and absolute value of PAL activity or content of total phenolate and flavoniods at a certain stage.

生理生化特性研究还表明，不同基因型健康穗或接种穗PAL活性、总酚及类黄酮含量存在显著差异，与材料的抗赤性无一定顺序关系。

The chemical composition research aspect literature report are extremely few: According to reports, the root of Rosa davurica pall includes the lactone, the tanning substance, the return to original state sugar, the total lucoside, the flavanone, the phenol class, the biological alkalis, the protein, the anthraquinone equi com ponent, moreover ,the total polysaccharide is the even polysaccharide which is composed by the fructose.In 1999, for the first time from puncture the root in the alcohol extraction to sep arate Oleanic acid. And used the double wave length thin layer scanning method to determine the uneven pillar tartaric acid in to puncture in the root ontent.

化学成分研究方面文献报道极少：据报道，山刺玫根中含有内酯、鞣质、还原糖、总苷、黄酮、酚类、生物碱类、蛋白质、蒽醌等成分，而且山刺玫根中总多糖是由果糖组成的均多糖。1999年，首次从刺玫根的乙醇提取物中分离出齐墩果酸，并采用双波长薄层扫描法测定了齐墩果酸在刺玫根中的含量。
