| 摘 要： | 以3年生早钟6号枇杷(Eriobotrya japonica Lindl.)容器苗为试材,采用100.0 mmol/L钙调素拮抗剂三氟拉嗪(Trifluoperazine,TFP)的Hoagland营养液砂培法预处理24 h后,于-3℃人工气候室进行低温胁迫,研究钙调素拮抗剂TFP对低温胁迫下枇杷幼果AsA-GSH循环的影响。结果表明:TFP处理导致低温胁迫下枇杷幼果H2O2含量高于单一低温胁迫的LTS处理(Low Temperature Stress,LTS),而AsA和GSH含量低于LTS处理,且两者差异达显著水平(p<0.05);同时GR、DHAR、MDAR、APX活性也受到不同程度的抑制,其中对APX和GR活性的抑制作用较为明显。TFP预处理削弱了枇杷幼果低温胁迫后的抗氧化能力,加重了低温胁迫对幼果的伤害,表明低温胁迫下枇杷幼果的AsA-GSH循环受Ca2+.CaM信使系统的诱导和调控。
