Fig 1. Alteration of cell membrane stability and lipid peroxidation in the leaf of bermudagrass after treated with nitric oxide (NO) donor and inhibitor under cold stress.

(A) malonaldehyde (MDA) content; (B) electrolyte leakage (EL). Experiments were repeated for three times, and means were average values of MDA and EL content, respectively. Independent-samples t test was used to determine statistical differences. Bars show standard deviation. Different letters indicate statistical difference significance at P < 0.05 among the treatments. CK was control that treated with sterilized water, SNP was plant treated with SNP, P+L was plant treated with PTIO and L-NAME. FW was fresh weight.
