为给樱属植物的形态学研究提供解剖学依据,同时为其引种栽培提供理论依据,以湖南省森林植物园引种栽培的10个樱花品种的1年生茎为试验材料,采用植物显微技术,观察其解剖结构,比较分析其髓率、木质部率、韧皮部率、皮层率、周皮率和导管分子的形态特征及数量特征.观测结果表明:10个樱花品种1年生茎部的各个结构参数间均存在显著差异(P

In order to offer a basis for morphological studies on Cerasus,and to provide a theoretical basis for introduction and cultivation of Cerasus,using one-year-old stems of 10 Cerasus cultivars planted in Hunan Forest Botanical Garden as materials,stem anatomical structures were observed by using plant microscopic techniques,and some morphological and quantitative characteristic indexes of stem were compared,including pith rate,xylem rate,phloem rate,cortex rate and periderm rate and vessel segment.The results of observation indicated that structu...
