摘 要:为充分揭示不同地榆属(Sanguisorba)植物对环境的适应性,以地榆(S.officinalis)、细叶地榆(S.tenuifolia)和宽蕊地榆(S.applanata)的叶片和茎为材料,采用常规石蜡切片技术对其进行解剖学比较研究。结果表明,3种地榆属植物叶片形态表现出同一性和差异性,其显微结构呈现典型的双子叶植物特征,上表皮细胞均大于下表皮细胞;细叶地榆、宽蕊地榆与地榆相比在叶脉厚度、栅栏组织厚度上差异显著,在维管束长度、上下角质层厚度、下表皮细胞厚度上无显著差异;茎解剖结构显示地榆维管束数量多于细叶地榆与宽蕊地榆,维管束面积表现为宽蕊地榆>细叶地榆>地榆。上述研究明确了地榆属植物的生物学特性,可为地榆属植物的栽培和高效开发利用提供理论依据。In order to fully reveal the adaptability of different Sanguisorba plants to the environment,leaves and stems of S.officinalis,S.tenuifolia and S.applanata were comparatively analyzed by paraffin sectioning methods.The results indicated that the leaf morphology of these three Sanguisorba plants showed identity and difference,and their microstructure showed typical characteristics of dicotyledon which upper epidermal cells were larger than the lower epidermal cells.Compared with S.officinalis,S.tenuifolia and S.applanata had significant differences in the thickness of leaf vein,palisade tissue,but there was no significant difference in the length of vascular bundle,the thickness of upper cuticle,lower cuticle and lower epidermal cells.The stem anatomical structure showed that the number of vascular bundle of S.officinalis was more than that of S.tenuifolia and S.applanata,and the area of vascular bundle was shown as S.applanata>S.tenuifolia>S.officinalis.The above results clarified the biological characteristics of Sanguisorba plants,which could provide a theoretical basis for the cultivation and efficient development and utilization of Sanguisorba plants.
