| 摘 要： | 对非洲菊的花粉形态进行了扫描电镜观察，对4个品种花粉活力和柱头进行了可授性测定，通过荧光显微镜观察了花粉在柱头的萌发情况，结果表明：非洲菊花粉粒为中等偏小型，具三孔沟。在部分ME，培养基中添加300g·L^-1 PEG1500的培养基比较适宜品种‘N2’花粉萌发，生活力最高达38．3％。多数品种的在刚散粉时期，22—28℃萌发能力强。柱头可授期可达12d。 |

| Abstract: | Test in vitro of germination indicated that the most optimized culture medium was part of ME3＋300 g·L^-1 PEG1500. The high- est germination rate in ＇N2＇was 38.3%. Effect of different flowering stages on pollen viability was significantly. The best condition for pollination was 22-28 ℃ and fresh pollen appearing. By means of benzidine-hydrogen peroxide reaction and aniline blue fluorescence method, showed that the stigma receptivity could teach to 12 days since flowering and the strongest in the inflorescence expanding. |
| Keywords: | Gerbera jamesonii pollen living ability stigma receptivity |
