The comparison of drought resistance of the four Eragrostis species

This study shows that the relative water content of the leaves of four Eragrostis species was obviously decreased under the situation of soil water stress. The order of drought resistance of the four species was: E. songmingensis E. xundianensis E. xundianensis var. E. curvula. The changes of relative water content in the leaves were consistent with the change of chlorophyll content in leaves.
