| 摘 要： | 通过对矮篙草不同时期花序生长发育的研究，观察到矮篙草在5月中旬已完成抽穗，6月主旬进入盛花期，6月中旬和7月初形成果实雏形，7月底和8月上旬果实成熟。平均每穗结实3-7粒，约48％的雌蕊发育成果实。矮篙草花序长9．5～ll，9mmtJ卜穗数7．2～10．2个／花序，小穗长4．1—5．1mm，雌花数6．2～13．7个／花序，雌蕊数为0．7l～1．60个／小穗。果实数3．0—6．6粒／花序。

| Abstract: | The reproductive growth of Kobresia humilis in different period were studied.It was discovered that Kobresia humilis had already finished that tasseled at the middle ten day of May, entered hull bloom stage at the first ten day of June, formed embryonic state of seed at the middle ten day of June to the first ten day of July and matured at the last ten day of July to the first ten day of August. It was average 3-7 seeds per anthotaxy and the fruits developed from 48% among gynoecia. It was also observed that the anthotaxy and spikelet length,the spikelets per anthotaxy, the female flowers per anthotaxy and spikelet and the seeds per anthotaxy of Kobresia humilis were 9.5-11.9mm and 4.1-5.1mm, 7.2-10.2, 6.2-13.7 and 0.71-1.60 and 3.0-6.6 separately. |
