柿属6种药用植物营养期叶片辅助鉴别研究

为建立柿属药用植物的营养期辅助鉴别方法,对该属6种植物的叶片脉序、叶表皮形态、叶解剖结构、叶粉末等特征进行比较观察。结果表明所观察的该属植物叶片的二级脉与三级脉具有鉴别意义;该属植物叶表皮皆具有单细胞非腺毛,大多具有腺毛;个别种的粉末中可见石细胞。通过研究,获得了柿属药用植物叶片的主要区别点,并据此建立了实用的鉴别检索表,为柿属药用植物的营养期鉴定和柿叶生药基原植物的准确鉴定提供了科学依据。

Identification of six species of medicinal Diospyros plants based on leaf macro- and micro-morphology

To establish a method for the identification of five species and one variety of medicinal plants from Diospyros, their leaf veins, epidermis, anatomic and powder characters were observed and compared with macro-morphological and microscopic methods. The results indicated the differences of secondary and tertiary veins among those Diospyros species. The single cell non-glandular hair and glandular hair exist in most species'' epidermis while stone cells were only found in the leaf powders of two species. Through the study, the main differences of leaf macro- and micro-morphology of these species were obtained and practical keys were also established, which can provide scientific base not only for identification of these species during their vegetative stages, but also for accuracy authentication of the source of Kaki Folium.
