摘　　要：槲蕨的干燥根茎是中药材“骨碎补”的正品。由于其生长环境特殊,尚未实现人工种植。为了野生资源的可持续发展与合理利用,通过野外观察,描述槲蕨的生活习性,揭示其根茎的生长模式,确定根茎年龄的判断方法,并分析不同年龄根茎干质量的增长规律和柚皮苷的累积规律。结果表明,不同分布区槲蕨的生活习性存在一定的差异,根茎具明显的节和节间,类似圆锥花序轴的生长模式,不同年龄根茎的干质量无显著差异。槲蕨根茎中的柚皮苷,1年生根茎中含量最高,随着生长年龄升高含量下降,且多年生各年龄间没有显著差异;附生于石壁上的槲蕨根茎的柚皮苷含量显著高于附生树干上的槲蕨根茎。这些发现将为槲蕨野生资源的合理利用和开展人工种植提供指导。Dry rhizome of Drynara roosii is a traditional Chinese medicinal material,named as“Gu-suibu”.Due to its particular habitat environment,there is no artificial cultivation at present.For the sustainable development and reasonable use of wild resources of medicine,the living habits of the herb were discribed throngh field observation and the growth pattern of this fern rhizome was revealed.Then the method for judging the age of the rhizome was determined,and the growth law of dry weight of the rhizome was analyzed.The content of naringin in the rhizome at different ages was determined by HPLC.The results showed that there were some differences in the habits of D.roosii in different districts.The rhizomes had distinct nodes and internodes,and showed a growth pattern similar to that of the panicle axis.There was no significant difference in the dry weight of the rhizomes at different ages.The content of naringin in the annual rhizomes was the highest,then decreased and there was no significant difference in the cotents at different ages.The content of naringin rhizomes of the D.roosii attached to the cliff was obviously higher than that of the epiphyte of the trunk.The results of this study will provide guidance for rational utilization and artificial cultivation of wild resources of this herb.
