This experiment was conducted in factorial format and in the form of RCBD with 3 replications. The treatments used included four concentrations of salicylic acid and thiamine. Application of salicylic acid caused significant changes at 1% and 5% levels in all morphological and physiological traits except the number of flowers in the cluster, relative leaf water content, and acidity. Spraying salicylic acid on the leaves of tomatoes increased some traits such as yield, number of fruits in plant, number of bunches in plant, and compared to control plants (without application of salicylic acid). Thiamine spraying caused significant changes in most of the morpho-physiological and quality traits. Thiamine caused an increase in the traits that were significant, although this increase was influenced by the concentration of the used. The yield (4084 and 4225 kg for the application of salicylic acid and thiamine), vitamin C (42 and 51 mg/g fresh weight for the application of salicylic acid and thiamine), and lycopene (2.34 and 2.49 mg/g) fresh weight for the application of salicylic acid and thiamine) traits had the highest amount of salicylic acid and thiamine at a concentration of 100 mg/liter. Some of the traits such as yield, fruit diameter, fresh and dry weight, total acidity, phenolic acid, and vitamin C were also affected by the interaction of salicylic acid and thiamine. According to this study spraying of salicylic acid and thiamine with a concentration of 100 mg/liter will have the greatest effect on morphophysiological characteristics in Galaxy tomatoes under greenhouse conditions.
