18个品种三角梅花粉育性与花粉形态的观察

摘要

以18种三角梅花粉为研究材料，探索了适合花粉离体萌发的培养基，通过离体萌发培养法测定了花粉生活力，并按生活力大小进行了分级。同时利用显微镜观察其中7种三角梅的花粉形态，探讨了不同三角梅品种间花粉形态与育性的相关性，为三角梅的杂交授粉及新品种培育提供了参考。%Taking 18 species of Bougainv illea pollen as study material, Explored the suitable culture medium in vitro for pol-len germination, determined the vitality of pollen germination by vitro culture method, and graded according to the size of Bouga-invilleapollen viability .Meanwhile, observed the pollen morphology of 7 species of Bougainvilel a with microscope, studied the correlation between pollen morphology and fertility on different varieties of Bougainvillea, and provided reference for cross pollina-tion and new varieties cultivation of Bougainiv llea.
