蕤核的花粉形态及叶片微观结构
Pollen morphology and leaf microstructure of Prinsepia uniflora
摘要
Abstract
The method of scanning electron microscopy and light microscope were used to research the pollen morphology and leaf microstructure of Prinsepia uniflora. The results were as follows; the pollen was small, nearly spherical and radial symmetry with tricolpate, with striate on outer wall. The leaf was bifacial leaf, whose upper and lower epidermis cells had the stratum corneum. The stomata existed in lower epidermis with three statuses and sank slightly. Stomatal density was about 200 to 300 per square millimeter. The palisade tissue was constituted by the 2 to 3 layers cylindrical cells and packed tightly,while the spongy tissue was constituted by the tubular cells with large gap between cells. Although P. uniflora was mesophyte,the leaf microstructure approached to xerophyte feature.关键词
