Mu Us Sandy Land in China is well known for having experienced desertification. Thus, it is important to examine the use of native species for revegetation. Salix psammophila C. Wang et Ch. Y. Yang and Salix cheilophila Schneid. are native species in this region. We used the cuttings of both species grown under well-watered conditions. We measured the length and dry weight of the current-year shoots. As for the underground portion, we measured the length and dry weight of the primary lateral roots. Our results showed that the number of current-year stems of S. psammophila was smaller than that of S. cheilophila. The stem length and dry weight of current-year stems of S. psammophila tended to be longer than those of S. cheilophila. These results suggest that 1) apical dominance of S. psammophila was stronger than that of S. cheilophila, and 2) S. psammophila tended to distribute the photosynthetic product more effectively to the upper ground part than did S. cheilophila. These morphological differences between two species may indicate that the morphological adaptability of S. psammophila in a shifting sand dune environment is superior to that of S. cheilophila although both species are in the genus Salix and both life forms are of the same type.
