Elucidation of the adaptability of <i>Cinnamomum camphora</i> seedlings from different provenances <i>via</i> analyzing photosynthetic characteristics and anatomical structure.

ABSTRACT: Understanding intraspecific variation in photosynthetic capacity and leaf structure is critical for optimizing provenance selection of Cinnamomum camphora in afforestation and urban landscaping programs. In this study, we assessed the adaptability of C. camphora seedlings from four provenances (Fuzhou, Wuhan, Shenzhen, and Shanghai) by examining their physiological and anatomical traits under a common garden environment in Henan Province. A total of n = 80 three-year-old seedlings (twenty per provenance) were evaluated for photosynthetic parameters, stomatal characteristics, and leaf structural features. The results revealed that the net photosynthetic rates of C. camphora seedlings from four different provenance sites exhibited a "double-peak" curve and a photo
