中文摘要:
      为研究不同条件下的花粉特性及离体萌发,通过测定6个非洲菊品种的花粉形态、花粉数量和花粉活力,明确其花粉特性和不同条件下的花粉活力;利用spss 23.0软件进行花粉大小、形态指数和花粉数量的系统聚类分析。结果表明:6个非洲菊品种的花粉形态、花粉数量和花粉活力均存在差异。“玲珑”的花粉粒最大,“大雪菊”的花粉粒最小;“云南红”花粉数量最多,“玲珑”花粉数量最低;用花粉离体萌发法测定不同时期和温度下的花粉活力范围分别为2.75%~ 33.54%和0.37%~34.62%。系统聚类法以花粉粒粒长和花粉粒直径聚类,在组间距离为25处,6个非洲菊品种被划分为二大类,第一大类包括“大雪菊”、“拉丝”、“香槟”、“云南红”和“紫霞”,第二类中的“玲珑”单独聚成1类。
英文摘要:
      order to study the pollen characteristics and in vitro germination under different conditions, the pollen morphology, pollen quantity and pollen viability of 6 Gerbera jamesonii Bolus cultivars were determined, and the pollen size, morphological index and pollen quantity were systematically analyzed by using spss23.0 software. In order to study the pollen characteristics and in vitro germination under different conditions, the pollen morphology, pollen quantity and pollen viability of 6 African chrysanthemum varieties were determined. The results showed that there were differences in pollen morphology, pollen quantity and pollen viability among 6 Gerbera jamesonii Bolus cultivars. The pollen grain of "Linglong" is the largest, and that of "Daxueju" is the smallest; the quantity of pollen of "Yunnan Hong" is the most, and that of "Linglong" is the lowest; the range of pollen viability at different periods and temperatures determined by pollen germination in vitro is 2.75% to 33.54% and 0.37% to 34.62%, respectively. In the systematic clustering method, pollen grain length and pollen grain diameter were clustered. Six gerbera cultivars were divided into two categories at 25 distances between groups.The first category includes "Daxueju", "Lasi", "Champagne", "Yunnan Hong" and "Zixia", while "Linglong" in the second category is grouped into one group.
