通过对星星草独立分蘖丛的取样调查,定量地分析了开花期与籽实成熟期星星草分蘖丛构件的数量特征及其与无性系大小之间的关系。结果表明:星星无性系构件的数量决定于丛径的大小;其营养蘖数与生殖蘖数在籽实成熟期高于开花期。星星草分蘖株数量和生物量与丛径之间呈极显著的直线正相关关系,其相关性均在0.01水平有差异。
Based on the investigation of single tufts of Puccinellia tenuiflora through the sampling, in the paper the quantitative characters of modules and the relationship between the character and the colonel size of Puccinelila tenuiflora population at the flowering stage and the maturity stage in the Songnen Plains of China were analyzed. The results showed that the number of tillers of Puccinellia tenuiflora depended on its colonel size. Both the number of reproductive vegetative tillers and tillers were dominant at the maturity stage, but at the flowering stage. There was all linearity relation between the number of tiller and the biomass.
