短葶飞蓬总黄酮含量的生态生物学分析

目的：为研究短葶飞蓬总黄酮含量在个体器官间，个体间，不同地区和不同生境种群间的变化规律。方法：测定了云南邱北，昆明等8个地区，大理苍山不同海拔条件下生长和栽培的短葶飞蓬植株体内总黄酮含量。结果：不同地区生长的短葶飞蓬总黄酮含量不同，同一地区，总黄酮含量有随海拔升高而上升的趋势。植株地上部分茎，叶和花的总黄酮含量高于地下部分根的，生长在同一生境的短葶飞蓬不同个体总黄酮含量也有差异。结论：短葶飞蓬体内总黄酮含量的高低是基因和环境条件共同作用的结果。

Ecological and biological analysis of total flavonoids in Erigeron breviscapus

Object To study the regular change of total flavonoids in Erigeron breviscapus (Vant.) Hand-Mazz (TFE) in different parts of the plant, different individual plant and population from different habitat. Methods Samples of E. breviscapus from eight districts around Qiubei, Kunming and at altitude on Cangshan mountain, Dali were collected and their flavonoids determined.Results TFE showed different values in samples from different origin, with the tendency to show an increase with increase of altitude. The aerial parts including stem, leaf, and flower were higher than that of the underground root.E. breviscapus grown in the same ecological conditions also showed different TFE values from individual to individual.Conclusion Variation in TFE was influenced by the combined effects of genotype and ecological conditions.
