摘要
以火炭母和粗毛火炭母为试材,通过叶形态和脉序图谱鉴别法(LMVP)对火炭母与粗毛火炭母进行研究,以期找出二者的叶形态和脉序鉴别特征及区别。结果表明:火炭母和粗毛火炭母在叶形态和脉序的特征为叶卵形或长卵形;叶端渐尖;叶基部截形或宽心形,多不对称;叶缘浅波状;环节羽状脉序;网眼由1~4级脉围成,5级脉多为盲脉。不同的是火炭母的叶有时下面沿叶脉疏生短柔毛,而粗毛火炭母的叶脉上多具有较长的糙硬毛;叶脉上的糙硬毛是区别火炭母和粗毛火炭母较为明显的特征。
Taking Polygonum chinense and Polygonum chinense var. hispidum as materials, the identification characters of Polygonum chinense and Polygonurn chinense var. hispidum were studied by using LMVP (leaf morphological-venation pattern for identification Chinese herbs). The results showed that the shape of leaf ovate or long ovate; leaf apex acuminate ; blade base truncate or broadly cordate, usually asymmetric leaf margin shallowly undulate, the venation brochidodromous pinnate;the areoles were formed by veins from primary vein to quaternary vein,and quinternary vein was usually blind vein. The different identifieation characters of them was along the leaves below veins of Polygonum chinense sparsely were pubescent sometimes, but along the leaves below veins of Potygonum chinense var. hispidum were hispid. The hispid along the leaves below veins was an obvious character to identify Potygonum chinense and Polygonum chinense vat. Hispidum.
