摘要
通过对矮嵩草不同时期花序生长发育的研究 ,观察到矮嵩草在 5月中旬已完成抽穗 ,6月上旬进入盛花期 ,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 4 8%的雌蕊发育成果实。矮嵩草花序长9.5～ 1 1 .9mm,小穗数 7.2～ 1 0 .2个 /花序 ,小穗长 4 .1～ 5 .1 mm,雌花数 6 .2～ 1 3.7个 /花序 ,雌蕊数为 0 .71～ 1 .6 0个 /小穗 ,果实数 3.0～ 6 .6粒
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.
