目的:探究鼠李科鼠李属植物毛冻绿( Rhamnaceae utilis Decne. var. hypochrysa( schneid.)Rehd.)春季初萌发幼叶的显微鉴别特征。方法:徒手切片观察幼叶纵切结构和叶片上下表皮表面观,粉末显微辨识毛冻绿幼叶特征结构与形态。结果:毛冻绿非腺毛可分为长、短两种类型,非腺毛毛囊处的纵皱纹理明显,且放射性地向毛囊基部表面扩散。毛囊处于叶表皮细胞整体水平面以下且顶部细胞呈细长柱形,侧面观呈鞭状的非腺毛为长非腺毛;毛囊处于叶表皮细胞整体水平面上且毛囊与叶表皮细胞连接部分呈水滴状,短非腺毛侧面观近三角形;短非腺毛的分布常与叶肉细胞中的方晶伴生。结论:利用毛冻绿非腺毛的毛囊与叶表皮细胞连接的位置关系,及非腺毛长度的形态差异,可作为毛冻绿幼叶的显微鉴别提供依据。长短非腺毛在不同物候环境变化下,形态会有过渡性变化。长非腺毛可能与保障蒸腾与呼吸作用有关,短非腺毛可能与保护叶肉组织有关。
目的:探究鼠李科鼠李屬植物毛凍綠( Rhamnaceae utilis Decne. var. hypochrysa( schneid.)Rehd.)春季初萌髮幼葉的顯微鑒彆特徵。方法:徒手切片觀察幼葉縱切結構和葉片上下錶皮錶麵觀,粉末顯微辨識毛凍綠幼葉特徵結構與形態。結果:毛凍綠非腺毛可分為長、短兩種類型,非腺毛毛囊處的縱皺紋理明顯,且放射性地嚮毛囊基部錶麵擴散。毛囊處于葉錶皮細胞整體水平麵以下且頂部細胞呈細長柱形,側麵觀呈鞭狀的非腺毛為長非腺毛;毛囊處于葉錶皮細胞整體水平麵上且毛囊與葉錶皮細胞連接部分呈水滴狀,短非腺毛側麵觀近三角形;短非腺毛的分佈常與葉肉細胞中的方晶伴生。結論:利用毛凍綠非腺毛的毛囊與葉錶皮細胞連接的位置關繫,及非腺毛長度的形態差異,可作為毛凍綠幼葉的顯微鑒彆提供依據。長短非腺毛在不同物候環境變化下,形態會有過渡性變化。長非腺毛可能與保障蒸騰與呼吸作用有關,短非腺毛可能與保護葉肉組織有關。

Target:It is to probe the micromorphology feature on immature leaf of Rhamnus Utilis from Rhamnus L in spring. Method:sliced and Microscopic identification of powder is used. Result:Hon-glandular hairs of Rh-amnus Utilis have two types,long hair and short hair. Follicle of non-glandular hair has clear portrait texture, and radioactively stretches on the surface of follicle base. The follicle is under the whole epidermal cells level with slim column shape cells at the top,and the non-glandular hair with whip shape at the side,which is the long non-glandular hair. The follicle is over the whole epidermal cells level with water-drop shaped connection part between follicle and leaf epidermal cell,and the non-glandular hair with triangle shape is at side,which is short non-glandular hair. Short non-glandular hair usually live together with crystal in the mesophyll cells. Conclusion:the connection part of non-glandular hair follicle of Rhamnus utilis and epidermal cells,and mor-phological differences on the length of non-glandular can be the evidence for microscopic identification to imma-ture leaf. The shape for long and short non-glandular hair will have a transitional change due to the different living environment,which may be influenced by transpiration and respiration,and mesophyll respectively to long and short ones.
