Morphological, Physiological, and Biochemical Composition of Mulberry (Morus spp.) under Drought Stress

Drought is the most important environmental factor inhibiting plant photosynthesis. In this study, morphological characteristics, biomass allocation, and physiological biochemical characteristics of four potted mulberry plants under drought stress were analyzed. The study revealed tolerance differences seedlings in semi-arid sandy areas China. Combined with results two-way ANOVA, normal growth conditions, Shensang No. 1 Ji’an grew well produced higher benefits, which was attributed to their larger leaf areas, biomass, total Chl contents, there significant between other traits (p < 0.05). led a decrease photosynthetic capacity leaves, resistance capabilities trees different. Among trees, Aerxiang Fujia less affected by drought, cultivation naturally arid environment able achieve certain effects. branch length, area, specific area significantly differently correlated components’ dry weight, root root-to-crown ratio 0.05), also positive correlation fluorescence parameters GS, PIABS, ABS/RC, TRo/RC NSC Studies have shown that jointly affect growth. Our research will help screening providing data support for strategic planning subsequent breeding, maximizing quality resource benefits trees.
