【摘要】 调查观测茵芋的原生环境、生长特性及主要生物学特征,电镜显微和拍摄了子房结构、胚珠、花粉形态等,对茵芋主要生物学特征进行了补充记录。发现茵芋子代的雌雄株分化比例为11.2∶88.8,茵芋花粉形态为近球形辐射对称,花粉粒直径为31.2—44.6μm。茵芋花粉平均活力为55.92%,红墨水染色法和离体萌发法等能快速、准确、有效地测定花粉活力。更多还原

【Abstract】 A Study on the Skimmia reevesiana Fort is made concerning its primary environment, growth characteristics, and the main biological characteristics. First, the structure of its ovary, ovule, pollen morphology, etc. is observed through the microscopy research and technique, and then the main biological characteristics are filmed and recorded. It is found that for the offspring of the Skimmia reevesiana Fort,the male and female plant differentiation ratio is 11.2∶ 88.8, and the pollen morphology is in nearly spherical radial symmetry, the pollen grain diameter is 31.2 ~ 44.6, the pollen vitality is 55.92% on average, and that red ink staining method and vitro germination method can be used to determine the pollen vitality quickly, accurately and effectively.更多还原
