The results showed that:compared with the control, FA treatment significantly increased leaf water content and antioxidant enzyme activities, reduced the accumulation of reactive oxygen species, proline content and relative electrical conductivity, which reduced the damage of plants under drought stress. In addition, drought stress also caused changes in photosynthetic characteristics and chlorophyll fluorescence parameters, and FA treatment improved the utilization efficiency of light energy in plants and protected of photosynthetic apparatus by enhanced heat dissipation. This study confirmed that FA has some ameliorative effect on P.ostii under drought stress, which would lay a foundation for the cultivation of P.ostii in arid areas. %U https://bbr.nefu.edu.cn/EN/10.7525/j.issn.1673-5102.2020.03.005
