摘要
本文从种群水平,用相关分析的方法,对不同利用方式下单优种羊草草地羊草种群的生殖器官数量性状进行了分析。在短期割草小区,穗长随其株高、小穗数随其穗长均呈直线变化;在跃期割草和停刈休闲小区,穗长随其株高呈指数函数变化,小穗数随其穗长呈直线变化。小花数与其穗长和小穗数三者之间,在不同利用方式下均为直线相关。
The quantitative characters of sexual organs of Aneurolepidium chinense population were analysed by the method of correlation analysis on different utilization systems at the population level in this papers.On the short-term cutting plot,both the ear length with its stem high and the spikelet number with its ear length were linear function. On the long-term cutting plot and the resting plot of stopping cutting, the ear length was exponential function along with its stem high and the spikelet number was linear function along with its ear length. The floret number with its ear length and spikelet number according with correlation of linear functionon different plot of utilization systems.
