中文摘要 为揭示沿海沙地木麻黄人工林不同林窗大小下竹类植物的光合适应能力，以福建省东山赤山国有防护林场滨海沙地矢竹(Pseudosasa japonica)、实肚竹(Phyllostachys nidularia f. farcata)和绿竹(Bambusa oldhami)为研究对象，测定分析了不同林冠环境(大林窗、中林窗、林下)条件下3个竹种的PSⅡ实际光化学量子产量(Y)、光合电子传递速率(ETR)、光化学淬灭系数(qP)、非光化学淬灭系数(qN)、PSⅡ的潜在活性(F_v/F₀)和最大光化学效率(F_v/F_m)等叶绿素荧光参数的变化。结果表明，不同林冠环境对竹类植物的光合可塑性有显著影响，表现出种间差异性。3个竹种的F_v/F_m均随林冠光照强度的减弱而减小。矢竹的Y、ETR值在中林窗和林下较高，实肚竹在中林窗环境中较高，绿竹在大林窗和中林窗中较高。在林下弱光环境中，矢竹的光合电子传递和热耗散能力并未显著减弱，其F_v/F_m、Y及ETR值在林下环境均显著高于实肚竹和绿竹。实肚竹和绿竹光合电子传递的光能在林下弱光环境中受到了较为显著的影响。矢竹具有较强的弱光适应性，其光合效率和热耗散能力在不同光照强度的林冠环境中保持较高水平，而绿竹和实肚竹在林下弱光环境中的适应性相对较弱。本研究可为沿海防护林林下竹类植物引种及其光合适应性策略制定提供理论参考。

英文摘要 In order to reveal the photosynthetic adaptability of bamboo plants under the forest gaps of different sizes in Casuarina equisetifolia plantation along coastal sandy area, Pseudosasa japonica, Phyllostachys nidularia f. farcata and Bambusa oldhami are taken in Chishan State-owned Protective Forest Farm located in Dongshan, Fujian Province to measure and analyze the changes in chlorophyll fluorescence parameters of three bamboo species, such as PSII actual photochemical quantum yield (Y), photosynthetic electron transport rate (ETR), photochemical quenching coefficient (qP), non-photochemical quenching coefficient (qN), PSII potential activity (F_v/F₀) and maximum photochemical efficiency (F_v/F_m), under different canopy environments (large-sized forest gap, medium-sized forest gap and understory). The results show that different canopy environments have a significant impact on the photosynthetic plasticity of bamboo plants, exhibiting inter-species differences. The F_v/F_m of the three bamboo species decreases with the decrease of canopy light intensity. The Y and ETR values of P. japonica are higher in the medium-sized forest gap and understory, while those of P. nidularia are higher in the medium-sized forest gap, and those of B. oldhami are higher in the large-sized and medium-sized forest gaps. In the low light environment under forest, the photosynthetic electron transport and heat dissipation capacity of P. japonica are not significantly weakened, and its F_v/F_m, Y, and ETR values are significantly higher than those of P. nidularia and B. oldhami under forest. The light energy of photosynthetic electron transfer in P. nidularia and B. oldhami is significantly affected in the low light environment under forest. P. japonica exhibits better weak light adaptability, and its photosynthetic efficiency and heat dissipation capacity remain at higher level in canopy environments with different light intensities. However, B. oldhami and P. nidularia have relatively weak adaptability in low light environments under forest. This study provides a theoretical basis for bamboo plant introduction and the development of photosynthetic adaptation strategies for bamboo plants under coastal protective forests.
