在松嫩平原天然割草场光稃茅香种群的籽实成熟期 ,将广泛取样的 5 88个生殖分蘖株样本分为 10个高度级进行测定。分析的结果表明 ,株高与花序长度、营养生物量、生殖生物量、总生物量、籽粒千粒重均呈显著的正相关 ;与生殖生长比率、生殖分配 、生殖分配 、每个花序种子生产的数量、结实率均呈显著的负相关。生殖分蘖株数量特征的生态可塑性及其规律性变化 ,蕴涵着个体生长与生殖策略。
In the seed maturity stage of Hierochloe glabra population in the natural mowing grassland of the Songnen Plain, a total of 588 reproductive tillering samples were collected and divided into 10 levels. The results showed that there was a significant positive correlation between the plant height and the length of inflorescence, vegetative biomass, reproductive biomass, total biomass and grain weight per plant. The reproductive growth rate, reproductive allocation, reproductive allocation, the number of seed production per inflorescence , Seed setting rate showed a significant negative correlation. The ecological plasticity and regular changes of quantitative tillering plants imply individual growth and reproduction strategies.
