摘要 棕榈藤作为热带、亚热带植物中重要的森林资源,优质的藤材是重要的加工利用材料,具有重要的经济价值。叶片光合能力对藤材的形成具有重要影响,利用叶绿素荧光仪测定黄藤(Daemonorops jenkinsiana)、大白藤(Calamus faberii)、小白藤(C.balansaeanus)的叶绿素荧光参数,为研究逆境条件下棕榈藤的光合能力和选择适宜的栽培条件提供参考。结果表明,在实验室条件下3种棕榈藤的光系统Ⅰ(PSⅠ)实际光量子效率Y(Ⅰ)为小白藤 > 大白藤 > 黄藤,光系统Ⅱ(PSⅡ)的Y(Ⅱ)为大白藤 > 黄藤 > 小白藤;非光化学猝灭系数qN由高到低依次为大白藤、黄藤和小白藤;而光化学猝灭系数qP则是小白藤最高,黄藤次之,大白藤最低;PSⅠ的电子传递效率ETR(Ⅰ)是小白藤 > 大白藤 > 黄藤,而PSⅡ的ETR(Ⅱ)值则是小白藤 > 黄藤 > 大白藤;PSⅡ最大光量子产量Fv/Fm维持在0.78~0.8范围内,且大白藤显著高于黄藤和小白藤(P < 0.05)。由此可见,在实验室条件下小白藤的光合效率在这3种藤中最高,其次为黄藤,大白藤最低;且光保护能力为大白藤最高,黄藤次之,小白藤最低。

Abstract:As the important forest resource of tropical and subtropical plants, high quality rattans are important materials for processing and utilization which have great economic value. Leaf photosynthetic capacity has an important effect on the formation of rattan. The chlorophyll fluorescence parameters of Daemonorops jenkinsiana, Calamus faberii and C.balansaeanus were measured using chlorophyll fluorescence spectrometer, which will provide reference for the study on photosynthetic capacity of rattan and the selection of appropriate cultivation conditions. The result indicated that under laboratory conditions the value of photochemical efficiency Y (Ⅰ) in C.balansaeanus was the highest one, followed by those in C. faberii and D. jenkinsiana, and the value of Y (Ⅱ) in C. faberii was the highest one, followed by those in D. jenkinsiana and C.balansaeanus. The non-photochemical quenching coefficient (qN) ranked from high to low was in C. faberii, D. jenkinsiana and C.balansaeanus, and the photochemical quenching coefficient (qP) in C.balansaeanus wais the highest one, followed by those in D. jenkinsiana and C. faberii. Besides, the electron transport rate (ETR) of PSⅠranked from high to low was in C.balansaeanus, C. faberii and D. jenkinsiana, while that of PSⅡin C. faberii was the highest one, followed by those in D. jenkinsiana and C.balansaeanus. The average values of Fv/Fm of three rattan species ranged from 0. 78 to 0. 8, in which the value of Fv/Fm in C. faberii was obviously higher than those in other rattan species (P < 0. 01). Therefore, it could be concluded that under the laboratory conditions the photosynthetic efficiency of C.balansaeanus was the highest, followed by D. jenkinsiana and C. faberii, and C. faberii had the highest ability of photoprotection, followed by D. jenkinsiana and C.balansaeanus.
