Abstract

Water deficit is one of the most important environmental factors that regulate plant growth and development, and limits plant production. Nitric oxide (NO) is a diffusible gaseous free radical which is produced from L-arginine by Nitric oxide synthase (NOS).Low concentrations of NO inhibit the production of reactive oxygen species and protect plants against ROS damages. In this research the effects of Arg and SNP pretreatment on alleviation of drought stress in tomato plants, were studied and compared. In this research water stress induced the increment of MDA, hydrogen peroxide and carbonyl groups as indicator of oxidative stress. Results showed that total polyphenols, PROLINE, free amino acids and soluble sugar increased significantly under water stress.Pretreatment of plants with Arg and SNP reduced MDA and H2O2 content significantly.Pretreatment of plants with SNP reduced the carbonyl groups however the Arg pretreatment had no effects in this parameter. SNP pretreatment increased the total phenol content but had no significant effect on PROLINE and free amino acids. However Arg pretreatment had no significant effects on total polyphenols, but increased the PROLINE and free amino acids content. Both Arg and SNP pretreatment had no effects on photosynthetic pigments and SOLUBLE SUGARS. The application of the Arg and SNP inhibitors showed that the effect of SNP related to NO releasing and in the case of Arg, it seems that other pathways of Arg metabolism such as polyamines and PROLINE biosynthesis rather than NOS may activate.
