摘　　要：采用大样本随机挖取单个无性系的调查和测定方法,分析了松嫩平原碱化草甸朝鲜碱茅无性系冬眠构件的结构及其生长规律。结果表明,在生长季末期,朝鲜碱茅无性系冬眠构件是由冬眠苗和冬眠芽组成,其中,冬眠苗平均为72.27个±48.29个,冬眠芽为45.87个±26.27个。朝鲜碱茅无性系冬眠构件各组分具有相同的形成规律。冬眠苗数、冬眠芽数、冬眠构件总数均随着丛径、丛面积和亲株数量的增加呈幂函数异速生长。By the method of digging single clone in a large sample in random,this paper studied the structure and growth pattern of dormancy modules of Puccinellia chinampoensis clones on the alkalized meadow of Songnen Plain in China.The results showed that by the end of growth season,the dormancy modules of P.chinampoensis clones were consisted of dormancy seedlings and dormancy buds,with an average number being 72.27±48.29 and 45.87±26.27,respectively.The numbers of dormancy seedlings and dormancy buds and the whol...
