中文摘要：

用培养基发芽法研究沙芥花粉萌发特性；用人工异株授粉法和联苯胺-过氧化氢法测定柱头可授期。结果表明：沙芥花粉萌发的最佳培养基是20％蔗糖＋0．001％硼酸＋0．5％琼脂；花粉能够萌发的温度范围为15～38oC，最适萌发温度为25℃；从花蕾充分膨大期至开花后16h花粉活力较强，开花后48h花粉基本无活力；花粉储藏的适宜条件为低温（4℃），储藏期为7d。柱头可授期为开花前48h至开花后96h，开花后24～72h可授性强。

英文摘要：

Pollen germination characteristic of Pugionium cornutum （ L. ） Gaertner was evaluated by germination method on culture medium, its stigma receptivity was estimated by the hand cross-pollination and benzidine - H2O2 method. The results showed the optimal pollen germination of P. cornutum was on the culture medium added 20% sucrose, 0. 001% boric acid and 0. 5% agar. The effective temperature of pollen germination was from 15 ℃ to 38 ℃ and the optimal temperature was 25 ℃. The pollen germination rate was very higher from the biggest bud stage to 16 h after blooming, and the pollen viability was disappeared 48 h after blooming. The suitable condition of storing pollen was low temperature （4 ℃ ）, and storing period was 7 d. The stigma of P. cornutum had receptivity from 48 h before blooming to 96 h after blooming, the strong receptivity in 24 -72 h after blooming.
