摘　　要：对半夏属５个种７个群体植株的叶片进行了叶绿素含量测定和净光合速率日变化比较，发现半夏Ｐｔｅｒｎａｔａ（Ｔｈｒｎｂ）Ｂｒｅｉｔ和虎掌Ｐ．ｐｅｄａｔｉｓｅｃｔａＳｃｈｏｔ都较耐强光，但半夏的净光合速率较高。倒苗是半夏避旱的适应方式，鹞落坪半夏Ｐ．ｙａｏｌｕｏｐｉｎｇｅｎｓｉｓＸ．Ｈ．Ｇｕｏｅｔ．Ｘ．Ｌ．Ｌｉｕ适应性差，应就地保护。The experiment in measurement of chlorophyll content and comparison of diurnal courses of net phytosynthesis of 7 populations belonging to 5 species in Pinellia, showed that P.ternata can adapt to strong light more successful than the shadadapted species and populations of Pinellia can produce quickly more organic materials in bulbils and seeds.It was necessary to conserve P.yaoluopingensis.due to its bad adaptability.
