Histological Analysis of Different Tissue of Pulsatilla Koreana Nakai
摘要
Abstract
Anatomic differences of leaf,petiole and meristematic nodules of Pulsatilla Koreana Nakai were observed. Histological examination results showed that leaf structure of P.koreana possessed typical characters of bifacial leaves:epidermis cells have thick cuticle and are arranged in a tense way.On the petiole cross section,the vascular bundles of the petiole are arranged in triangle and have bundle sheath outside.The xylem cells are of V-shape.Shoot organogenesis and somatic embryogenesis through meristematic nodules underwent three steps of developmental events.(1 )Globular structure with in tightly arranged small and deeply stained cells,which had no obvious inner structures.(2)meristemat-ic nodules with multi nodule center and tracheids elements.(3)Finally,shoot organogenesis and somatic embryogenesis were developed from meristematic nodules.关键词
