The effect of spraying tryptophan on the physiological characteristics of the periwinkle plant (Catharanthus roseus L.) under drought stress
Ultimately, the application of tryptophan at concentration 250 ppm was effective in alleviating the adverse impacts of drought stress by enhancing dry weight, photosynthetic pigments, and antioxidant enzyme activities in the periwinkle plant, culminating in increases in vincristine and vinblastine levels by 193% and 138%, respectively, under severe drought stress (40% field capacity).
