从植物标本中获得了1002种兰花（占巴拿马和哥斯达黎加兰花总数的61%）的叶片碳稳定同位素组成数据，以调查景天科酸代谢（CAM）的发生。叶片材料的碳同位素组成显示出双峰分布，在千分之-28处具有模式，表明C（3）光合作用，并且在千分之-15处具有模式，表明明显的CAM光合作用。强CAM存在于9.5%的物种和31的162属研究。这些属中有12个以前不知道含有表现出CAM的物种。巴拿马和哥斯达黎加的兰花与他们的三角洲13 C值和所有已知的兰花属，拥有物种的能力，执行CAM的清单。(C)2010年，伦敦林奈学会，林奈学会植物学杂志，2010年，163，194-222。
Leaf carbon stable isotopic composition data for 1002 orchid species representing 61% of the total number of orchid species described for Panama and Costa Rica were obtained from herbarium specimens to survey the occurrence of crassulacean acid metabolism (CAM). Carbon isotopic composition of leaf material showed a bimodal distribution with modes at -28 parts per thousand, indicating C(3) photosynthesis, and at -15 parts per thousand, indicating pronounced CAM photosynthesis. Strong CAM was present in 9.5% of species and in 31 of 162 genera studied. Twelve of these genera were not previously known to contain species exhibiting CAM. A checklist of orchids of Panama and Costa Rica with their delta 13C values and an updated list of all known orchid genera that possess species with the ability to perform CAM are presented.
