Abstract
Effects of spermidine on relative water content,electrolyte leakage,MDA content,chlorophyll content,osmoregulatory solutes and soluble protein content of white clover(Trifolium repens)in leaves under PEG stress were analyzed.Under osmotic stress,exogenous spermidine significantly improved relative water content and effectively reduced the decomposition of chlorophyll in leaves;the treatment of exogenous spermidine maintained significant lower electrolyte leakage and MDA content and exogenous spermidine relieved the injury to membrane;the accumulation of soluble sugar,reducing sugar,free proline,betaine and soluble protein were significant higher in the treatment of exogenous spermidine,but no significant effect on free amino acid content.The results suggested that exogenous spermidine can effectively improve osmotic stress tolerance of white clover associated with the accumulation of osmoregulatory solutes which have the function of osmotic adjustment and osmoprotection.
