Photosynthesis is important in metabolic pathways and is influenced by environmental stress. Drought stress is one of the environmental factors that alter several regulatory mechanisms, resulting in yield loss in crop plants. Using the foregoing background information, four Mulberry (Morus alba L.) genotypes were chosen, namely MY-01, BP-01, PP-01, and G4 and experiments were carried out in potted plants under natural photoperiod conditions under normal and water stress conditions. Morphological and Physiological parameters such as plant height, no of leaves, no of branches, leaf area, leaf yield and photosynthetic rate, stomatal conductance, transpiration rates, relative water content, and plant growth and yield parameters were measured in control and drought-induced plants during the experiment. Water stress conditions significantly influenced the altering of all photosynthetic, plant growth, and yield parameters in water-stressed conditions compared to watered conditions, according to the results, all of the varieties in the order had significantly lower photosynthetic rates. The most important crop in the sericulture industry is mulberry (Morus alba L.). In this study, we show that water scarcity characteristics can be finely controlled by leaf gas exchange characteristics in 1-year-old field-grown mulberry genotypes (Selection-MY-01, BP-01, PP-01, and G4) subjected to water stress by withholding water for 10 days. Significant differences in net photosynthetic rates (Pn), stomatal conductance and transpiration rate, and intercellular CO2 have been observed among four mulberry genotypes. Among the four genotypes, G4 significantly higher rates in Morphological-physiological characters of both water treatments (control and during drought stress (DS).
