| 摘 要： | 研究了矮嵩草生长的一般规律，包括芽的发生、生长、成熟、死亡和分株的形成过程及二龄分蘖的形成。矮嵩草在5月中旬完成抽穗，6月上旬左右进入盛花期，7月底和8月上旬果实趋于成熟；平均每穗结实3～7粒，约48％的雌蕊发育成果实；随着无性系株丛年龄的增大，矮嵩草常形成“环”状株丛。

| Abstract: | Growth regulation of Kobresia humilis was studied, including bud formation, growth, mature, death and ramet formation of new tillers, the formative process of two-age-tiller. It finished tassaled in the middle ten days of May and reached to florescence in the first ten days of July, fruit matured in last June and first ten days of August. It produce 3 - 7 fruits per spikelet and about 48 percent pistil develop into fruit. Kobresia humilis often form ＂loop＂ genet with increasing age of clonal genet. |
