| Abstract: | To study the effect of simulated acid stress on the physiological characteristics of Pyropia haitanensis, different intensities of acid rain (pH values of 5.6, 4.5, 4.0, 3.5, respectively) were used in this study. Physiological indexes such as membrane permeability, antioxidant enzyme activity and chlorophyll fluorescence parameters were determined to compare the effects of acid rain stress on physiological characteristics of Pyropia haitanensis under proper drying and complete soaking, dark and light conditions. The results showed that: (1) After simulated acid rain exposure with different treatment methods, the tolerance of Pyropia haitanensis of proper drying treatment to acid rain was significantly greater than that of full soaking, and the tolerance of Pyropia haitanensis of dark treatment to acid rain was significantly greater than that of light treatment. (2) The physiological indicators of Pyropia haitanensis were most affected by acid rain stress with pH value of 3.5, while it showed mild tolerance to acid rain stress with pH value of 5.6. The current study provides a technical basis for the cultivation and management of Pyropia haitanensis under acid rain stress. |
