Abstract: The relation between soil moisture and the soluble sugar, the soluble protein, electrical conductivity, MDA and dissociate proline were researched. With the declining of soil moisture, the leaf of electrical conductivity of two wild rock-plant increased; the soluble protein increased a bit initially then decreased slowly; MDA content of the Pogonatherum panideum (Lam.) Hack submit uptrend. After falling first, Erioophorum comosum Nees rised. The soluble sugar of Pogonatherum panideum (Lam.) Hack increased initially then decreased. The Erioophorum comosum Nee presented slow uptrend always; the dissociate proline increased. Synthesize every index, drought resistance of the Erioophorum comosum Nee was more stronger than the Pogonatherum panideum (Lam.) Hack.

Key words: Pogonatherum panideum (Lam.) Hack, Erioophorum comosum Nees, drought stress, drought resistance
