| 摘 要： | 研究了松嫩草原盐碱草地上具匍匐茎禾草---小獐毛的种群密度、生物量与有性生殖间相关关系。结果表明,小獐毛种群的生殖枝密度、生殖枝生物量、Re1和Re2与营养枝密度和生物量之间呈显着正相关,但与匍匐茎密度和生物量以及匍匐茎营养枝密度和生物量间有显着的颉颃关系,呈显着负相关关系。

| Abstract: | Correlation analysis of Aeluropus littoralis var.sinensis population on Songnen salinized grassland shows that the density and biomass of sexual shoots, Re1 and Re2 had a significant positive correlation with the density and biomass of vegetative shoots, but a significant negative correlation with the density and biomass of stolons, and with the density and biomass of vegetative shoots of stolon. |
