Leaf physiological and anatomical responses of two sympatric Paphiopedilum species to temperature
文献摘要：
Paphiopedilum dianthum and P.micranthum are two endangered orchid species,with high ornamental and conservation values.They are sympatric species,but their leaf anatomical traits and flowering period have significant differences.However,it is unclear whether the differences in leaf structure of the two species will affect their adaptabilities to temperature.Here,we investigated the leaf photosynthetic,anatomical,and flowering traits of these two species at three sites with different temperatures(Kunming,16.7 ± 0.2 ℃;Puer,17.7 ± 0.2 ℃;Menglun,23.3 ± 0.2 ℃) in southwest China.Compared with those at Puer and Kunming,the values of light-saturated photosynthetic rate (Pmax),stomatal conduc-tance (gs),leaf thickness (LT),and stomatal density (SD) in both species were lower at Menglun.The values of Pmax,gs,LT,adaxial cuticle thickness (CTad) and SD in P.dianthum were higher than those of P.micranthum at the three sites.Compared with P.dianthum,there were no flowering plants of P.micranthum at Menglun.These results indicated that both species were less resistance to high tem-perature,and P.dianthum had a stronger adaptability to high-temperature than P.micranthum.Our findings can provide valuable information for the conservation and cultivation of Paphiopedilum species.
