摘要: 以凤丹为材料,研究阿魏酸(FA)对植株自然干旱胁迫的缓解效应。结果表明:与对照相比,FA处理可显著提高叶片含水量、抗氧化酶活性,降低活性氧积累、脯氨酸含量和相对电导率,从而减少干旱胁迫对植株的伤害。此外,干旱胁迫同样引起了光合特性与叶绿素荧光参数发生变化,而FA处理不仅提高了植株的光能利用效率,而且增强了叶片的热耗散,进而维持了光合机构的完整性。本研究明确了FA对凤丹干旱胁迫具有一定的缓解效应,这可为凤丹在干旱地区的栽培奠定基础。

Abstract: Paeonia ostii was used to study the ameliorative effect of ferulic acid(FA) on plants under natural drought stress. 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.

Key words: Paeonia ostii, drought stress, ferulic acid
