| 摘 要： | 通过野外观察檫木Sassafras tzumu（Hemsl.）Hemsl的开花过程,用联苯胺—过氧化氢法测定其柱头可授性,TTC的方法测定檫木花粉活力。结果表明：柱头具可授性时间为8 d,檫木的花粉活力持续时间为32 h。根据测定时间发现柱头可授期和花粉活力较强期重叠较长,通过后期观察到檫木有结实,说明檫木具有正常的传粉机制和结实能力。

| Abstract: | Flowering process of Sassafras tzumu （Hemsl.） Hemsl was observed in the wild, stigma receptivity of sassafras tzumu was evaluated with benzidine-H202 method, and pollen viability of sassafras tzumu was evaluated with TrC method. The results showed that stigma can be granted with 8 days, pollen viability of sassafras tzumu has durative 32 hours. According to the measured time to discover stigma receptivity and pollen viability stronger has a longer period of overlap, later period observation showed that sassafras tzumu have fructify, which indicated that sassafras tzumu has normal pollination mechanisms and fructification ability. |
