| 摘要: |
| 目的 探讨不同光照条件对浙贝母生理特性、生物碱含量及生物量的影响规律。方法 采用遮阴网遮阴，共设置了4种光强处理，分别为不遮阴（CK）、遮阴50%（T1）、遮阴75%（T2）、遮阴95%（T3），测定各遮阴处理下浙贝母光合作用参数、生物碱含量和生物量。结果 遮阴对浙贝母光合作用、生物量和生物碱含量有明显影响，适度遮阴可以增大浙贝母净光合速率；透光率在5%时会严重影响浙贝母产量，但能明显增加生物碱贝母素甲的含量。结论 75%遮阴条件下，有助于增大浙贝母的净光合速率，有利于其光合作用的进行。95%遮阴条件下，严重影响浙贝母生物量的累积。遮阴度与生物碱两者之间并不完全平行。 |

| Abstract: |
| OBJECTIVE To investigate the laws how light intensities affect the physiological characteristics, alkaloid contents and biomass of Fritillaria thunbergii Miq. METHODS With plastic net shading, four types of light intensities were set, including the light transmittance of 100%(control group CK), 50%(group T1), 25%(group T2) and 5%(group T3). Then photosynthesis parameters, alkaloid content and biomass in different shading treatments were detected separately. RESULTS Shading significantly impacted the photosynthesis, alkaloid contents and biomass of Fritillaria thunbergii Miq. Moderate shading accelerated net photosynthesis. The yield of Fritillaria thunbergii Miq. was reduced at the light transmittance of 5%, but the content of alkaloids was significantly increase. CONCLUSION The 75% shading condition helps to quicken the net photosynthesis of Fritillaria thunbergii Miq. and was beneficial to its photosynthesis, while the 95% shading condition seriously inhibites the biomass accumulation. The degree of shading is not sampletely parallel to the alkaloid. |
