| 摘 要： | 为探讨不同施肥条件下栽培川西獐牙菜对高原强太阳辐射的生理适应特征,以藏药植物栽培川西獐牙莱为研究材料,测定其叶片中的叶绿素、类胡萝卜素及紫外线吸收物质的含量,探讨其在高原强太阳辐射下生理适应中的作用.结果表明,施氮肥能显著增加栽培川西獐牙菜叶片中的叶绿素a、叶绿素b和总叶绿素的含量,施肥(氮肥与磷肥)对叶片中花青素、类黄酮含量积累的影响不大.施氮肥有利于栽培川西獐牙菜叶片中叶绿素含量的积累,3种处理中类胡萝卜素和紫外线吸收物质含量的积累相差不大,说明栽培川西獐牙菜已经对高原强紫外线辐射有较强的适应性. |

| Abstract: | The aim of the research was to discuss the physiological adaptation characteristics of Swertia mussotii cultivated under different fertilization and strong ultraviolet radiation of plateau. The contents of chlorophyll, carotenoid and ultraviolet absorption substances were determined. The results showed that nitrogenous fertilization remarkably increased the contents of chlorophyll a, chlorophyll b, total content of chorophyll in the leaves of Swertia mussotii cultivated in the same environ- ment,.
