中药梅花花粉的形态学研究

Studies on Pollen Morphology of Prunus mume

利用光学显微镜和扫描电镜,观察了采自上海、杭州、长兴的24个梅品种花粉。发现梅花花粉具有多型性,可分为2类5型,花粉粒有3孔沟类型和4孔沟类型,其中具3孔沟的花粉粒占主导地位。作者对各品种的花粉形态组成及中品种花粉的败育率进行了分析。为梅花的花粉鉴别、品种选育、分类及孢粉学提供了依据。

The pollen grains of 24 cultivarieties of Primus mimic of Rosaceae, which were collected from Shanghai, Hangzhou and Changxing. were observed by light microscope and scanning electron microscope. The pollen morphology of P.mume was first described as polytypism which could be distinguish into two classes and five types. Not only the pollen grains with 3-colporate. which were the primary form, but also the pollen grains with 4-colporate existed in many cultivarieties of P- tnume. The constitute of pollen types and sterility rate in each cultivarieties were also analysed. The result provides scientific reference for pollen identification, breeding and palynology.
