Abstract
The effects of exogenous melatonin on physiological indexes of tomato seedling under low temperature stress includes malondialdehyde content,proline content,chlorophyll content,and the metabolism of active oxygen.The results indicate that exogenous melatonin could effectively improve the cold resistance of tomato seedlings.By comparison,the relative conductivity and malondialdehyde(MDA)content are decreased by 39.3% and 31.0%respectively,and maintain the integrality of cell membrane.At the same time,the activities of superoxide dismutase(SOD),peroxidase(POD)increase by 39.2%,48.2%,and the permeate(proline)content increases by 52.8%in tomato seedlings,thus it has enhanced the cold tolerance of the seedlings.
