| 摘 要： | 以宁夏枸杞"宁杞I号"为试材,通过防雨棚下测坑试验进行灌水量控制,灌水量依次为0、150、300、450、600 m2/667m2,采用紫外分光光度法测定枸杞子总黄酮,研究不同水分胁迫对宁夏枸杞子总黄酮含量的影响。结果表明:在水分胁迫初期,不同处理枸杞子中总黄酮差异不大,其含量在0.703%～0.709%之间;水分胁迫中期,随着灌水量的增大,枸杞子中总黄酮均呈增大趋势,但增长率呈现先增加后减少的趋势,其增长率分别为31.41%、61.84%、72.64%、87.17%和41.50%;水分胁迫后期,随着灌水量的增大,总黄酮减少率也呈现先增大后减少的趋势,其减少率分别为13.67%、48.35%、29.23%、16.05%和8.28%。表明适宜的水分胁迫有利于枸杞子中总黄酮的积累。

| Abstract: | The effects of water stress on flavonoids content of dried Lycium barbarum were studied with Ningqi 1.Test pit experiment was carried out under five levels of water supply treatment in a rain shelter.The results showed that in the early water stress,the content of total flavonoids of different treatment had little difference,the data were between 0.703% with 0.709%.In the medium-term of water stress,with the increase of irrigation amount,which showed increasing trend of total flavonoids,but the rate of the ... |
