Other AbstractQuercus aquifolioides, an evergreen alpine and subalpine species, is endemic to northwestern Yunnan, western Sichuan and eastern Tibet in China. We measured malondialdehyde (MDA) and proline (Pro) contents in leaves, shoots, bark and fine roots of Q. aquifolioides shrubs along an altitude gradient ranging from 3,000 to 3,950m on the eastern slope of Zheduo Mountain in western Sichuan. The results showed that leaves possessed significantly higher contents of MDA and Pro than other tissues; MDA and Pro contents in above-ground tissues increased with increasing altitude, but contents in fine roots had no significant difference among elevations; except for MDA contents in fine roots, MDA content in other tissues and Pro contents in all tissues of Q. aquifolioides shrubs had positive correlations with atmospheric temperature and precipitation. The results suggest that in subalpine and alpine environment, Q. aquifolioides’ growth is limited by cold and drought stress. The contents of MDA and Pro in Q. aquifolioides are correlated with stress degrees.
