摘  要:
通过对星星草独立分蘖丛的随机取样的调查研究与测定,对不同样地星星草无性系分蘖株数量特征做定量研究。结果表明:在松嫩平原生长季末期,碱化草甸星星草的冬眠构件是由越冬芽和越冬苗组成,割草样地和休闲样地星星草种群均以越冬苗占优势地位,割草样地越冬苗数量是休闲样地的1.86倍,越冬芽数量割草地大于休闲样地,割草样地和休闲样地星星草无性系冬眠构件越冬苗的数量与越冬芽的数量均随着丛径的增加呈直线函数增加,其相关性达到极显著水平(P<0.01)。

摘  要:
Analysis of the quantity characteristic of tillers on Puccinellia tenuiflora clones in different sites was studied and measured on single tufts of P.tenuiflora that were random sampled.The result showed that the dormancy modules of P.tenuiflora clones were consisted of dormancy seedlings and dormancy buds at the end of the growing season on the alkalized meadow of Songnen Plain of China.Dormancy seedlings were dominant in the pasture for cutting and grazing.The number of dormancy seedlings in mowing plot was 1.86 times that of resting plot.The number of dormancy buds in mowing plot was more than that of resting plot.The numbers of dormancy seedlings and dormancy buds both in mowing plot and resting plot were all linearly increased with the diameter of the cluster increasing,which were all reached significance level(P<0.01).
