摘要
以银杏叶为材料,用光合作用测定系统测定不同品种净光合速率,用分光光度法测定黄酮含量。研究结果表明,不同银杏品种净光合速率和黄酮含量差异均很明显,黄酮含量与净光合速率之间有联系,但彼此之间的线性关系不明显。总体来看,净光合速率高的品种,其黄酮含量也高,因此在净光合速率高的银杏中选择叶用品种较合适。
Using the leaves of Ginkgo biloba L. as sample,net photosynthetic rate and total flavonoids content were tested by photosynthesis system and spectrophotometry respectively. The results showed that there were significant difference of net photosynthetic rate and total flavonoids content among different Ginkgo biloba L. varieties. There was a certain linear relationship between net photosynthetic rate and total flavonoid content , but the relationship was not obvious.Generally ,the Ginkgo biloba L. variety with high net photosynthetic rate also had high flavonoid content.It was reasonable to select the Ginkgo biloba L. varietiy with high net photosynthetic rate for leaf use.
