摘　　要：【目的】选育和推广适宜云南省高寒地区种植的百脉根品种。【方法】选取野生中甸百脉根和帝国百脉根为材料,对其在云南省迪庆州高寒地区的植株形态特征、生物量和生理指标进行了测定分析。【结果】帝国百脉根自然高度、拉直高度、叶长、叶宽、地上部分以及地下部分的鲜重干重均显著高于中甸(P<0.05),而茎叶比显著低于中甸(P<0.05)。生理分析表明:帝国百脉根根部丙二醛、脯氨酸含量显著低于中甸(P<0.05),而根部可溶性糖含量、超氧化物歧化酶、过氧化物酶活性显著高于中甸(P<0.05)。二者叶片中可溶性糖、可溶性蛋白、脯氨酸含量以及相对电导率差异并不显著(P>0.05)。【结论】综合分析认为帝国百脉根植株更高大,茎叶比小,牧用经济性高,适应性更强。在迪庆州香格里拉县试验基地或者在与其相似的地域和气候环境中种植,帝国百脉根的产量和适应性优于中甸百脉根。[Purpose]Our aim was to extend the suitable variety in the alpine region of Diqing.[Method]Lotus corniculatus L. cv. Zhongdian and Empire were studied as the experimental materials and their performances were evaluated by morphological characteristics, biomass and physiological indexes. [Result]The natural height, straighten height, leaf length, leaf width, fresh and dry weight of above-ground and below-ground of Empire were all significantly higher than those of Zhongdian（P0.05）, while the stem-leaf ratio of the Empire were remarkably lower than that of Zhongdian（P〈0.05）. Physiological analysis showed that the malondialdehyde and proline contents in root of Empire were significant lower than those of Zhongdian（P〈0.05）, whereas the content of soluble sugar and the activities of superoxide dismutase and peroxidase in root of Empire were significant higher than those of Zhongdian（P〈0.05）. In addition, no significant difference in the content of soluble sugar, soluble protein, proline and relative electrical conductivity were observed between two studied L. corniculatus（P〉0.05）. [Conclusion]Comprehensive analysis showed that Empire had the higher economic performances and the better adaptability than Zhongdian due to its higher stem,lower stem-leaf ratio. Planted in the test base of Shangri-La County in Diqing or the areas with similar geographical and climatic environment, the yield and adaptability of L. corniculatus L. cv. Empire were better than those of L. corniculatus L. cv. Zhongdian.
