Abstract:In order to study on the photosynthesis characteristics of new variety of Lonicerae japonicae Flos.Huajin 2,using the traditional variety as a reference,their photosynthetic parameters were dertermined by LI-6400Ⅺ portable photosynthesis system.The results showed that Huajin 2 had double peaks.The Pn of the Huajin 2 were very significantly positively correlated with Cond and PAR,significantly positively correlated with Ta and Tr,significantly negatively corrected with Ci,and not significantly correlated with RH.The maximum net photosynthetic rate and the light saturation point (LSP) of Huajin 2 were 13.91、1 426.67 μmol · m-2· s-1 respectively,which were higher than those of traditional variety (13.06,1 065.33 μmol · m-2· s-1).While the light compensation (LCP) of Huajin 2 (40 μmol · m-2· s-1) was significantly lower than that of traditonal variety (56 μmol · m-2 · s-1).In conclusion,Huajin 2 had wider range of photosynthetic adaptation,stronger shade tolerance and higher photosynthetic rate,which was the premise of high yield of plants.In this paper,the preliminary study on photosynthetic characteristics provided a basis for the promotion and cultivation of new variety of Lonicerae japonicae Flos.Huajin 2.
