沙鞭(禾本科)种子在沙丘上的萌发策略及幼苗的耐干燥特性

Psammochloa villosa is a sand dune perennial grass mainly distributed in the moving sand dunes of Ordos Plateau, China. This species is one of the pioneer plants of sandland vegetation succession, and is usually found in sand dune habitats. It occurs in large sand covered areas where desertification is becoming quite serious. A general survey indicated that seed germination is quite low and slow, and only a few new seedlings each growing season can be found in their natural habitats. Hardly any research ha...
