The effect of exogenously applied nitric oxide on the heat tolerance of Chrysanthemum morifolium was investigated by applying the NO donor sodium nitroprusside (SNP). We found that the SNP partially alleviated the heat stress by slowing down the reduction of photosynthetic pigment content and net photosynthetic rate. SNP treatment also lowered the increase in the non-photochemical quenching of fluorescence and malondialdehyde content and maintained higher activities of superoxide dismutase, peroxidase, catalase and ascorbate peroxidase.
