| 摘 要： | 通过对籽实成熟期星星草独立分蘖丛的取样调查,定量地分析了松嫩平原星星草无性系生殖株生物量的数量特征.结果表明:在籽实成熟期,割草地每丛中星星草丛生殖株数量、丛生殖株生物量、丛茎生物量、丛花序生物量分别为放牧地的1.30倍、1.39倍、1.33倍和1.22倍;叶生物量平均值表现为放牧地大于割草地,为割草地的1.51倍;两样地星星草无性系丛生殖株组分生物量与丛生殖株生物量、丛生殖数量、丛叶生物量之间均为幂函数变化,各自的相关性均达到了极显著水平(P<0.01).

| Abstract: | By sampling and investigating on single tufts of Puccinellia tenuiflora,the paper analysed the quantitative characters on the quantitative characters on reproductive biomass in the clone of Puccinelilia tenuiflora at anthsis stage in the Songnen plains of China.The results showed that the reproductive number,the reproductive biomass,the stem biomass and the spikelet biomass of the tuft of P.tenuiflora for cutting were1.30 times,1.39 times,1.33 times and 1.22 times for grazing.The average biomass of leaf for... |
