Abstract
The halophyte Arthrocnemum macrostachyum is able to survive in extreme environments where salt concentrations may rise to 1 M NaCl. Here we report the results of a study in which the photochemical properties of both photosystem (PS) PSII and PSI have been investigated in individuals living in their natural environment (Sacca di Bellocchio, Prato Zangheri, Ravenna, Italy) by using Pulse amplitude modulation and fast fluorescence techniques. Results from quenching analysis (for both photosystems) and fluorescence decay in the sub-millisecond range (for PSII) are reported and discussed in terms of adaptation mechanism(s) of these plants to this extreme environment.
盐生植物大stachyum能够在盐浓度高达1 M NaCl的极端环境中生存。在这里，我们报告了一项研究的结果，用光系统(PS) PSII和PSI的光化学性质已经研究了个体生活在他们的自然环境(Sacca di Bellocchio, Prato Zangheri, Ravenna，意大利)使用脉冲幅度调制和快速荧光技术。从猝灭分析(光系统)和亚毫秒范围内的荧光衰减(PSII)的结果报道和讨论了这些植物对这种极端环境的适应机制。
