“…Osmotic adjustment is impaired in sensitive plant species. A previous study on lettuce also showed a decrease in water content with an increase of V concentration [ 42 ]. Under heavy metal stress, various studies also reported a reduction in RWC in the leaves of barley and maize [ 43 , 44 ].…”

“…The reduction of osmolytes, such as proline, soluble sugars, and proteins are linked with the leaf water content, which could lead to cellular desiccation and osmotic stress in sweet potato ( Figure 6 ). According to the previous literature, plants exhibit a similar pattern by increasing proline and soluble sugars in response to increased cellular desiccation under V stress [ 6 , 11 , 22 , 42 ]. These osmolytes increase under abiotic stress conditions [ 17 , 32 ].…”

“…A previous study reported that tomato plants treated with V have more V in the roots than in the leaves [ 36 ]. In the same way, lettuce, tobacco, alfalfa, milkvetch root, and swamp morning glory treated with V also showed the same trend, and they have more V accumulation in roots than the leaves [ 1 , 10 , 35 , 42 ]. Generally, the increase in chlorophyll level characterizes plant photosynthesis assimilation and growth.…”

Vanadium (V) is a heavy metal found in trace amounts in many plants and widely distributed in the soil. This study investigated the effects of vanadium concentrations on sweet potato growth, biomass, root morphology, photosynthesis, photosynthetic assimilation, antioxidant defense system, stomatal traits, and V accumulation. Sweet potato plants were grown hydroponically and treated with five levels of V (0, 10, 25, 50, and 75 mg L−1). After 7 days of treatment, V content at low concentration (10 mg L−1) enhanced the plant growth and biomass; in contrast, drastic effects were observed at 25, 50, and 75 mg L−1. Higher V concentrations negatively affect the relative water content, photosynthetic assimilation, photosynthesis, and root growth and reduce tolerance indices. The stomatal traits of sweet potato, such as stomatal length, width, pore length, and pore width, were also decreased under higher V application. Furthermore, V concentration and uptake in the roots were higher than in the shoots. In the same way, reactive oxygen species (ROS) production (hydrogen peroxide), lipid peroxidation (malondialdehyde), osmolytes, glutathione, and enzymes (catalase and superoxide dismutase) activities were increased significantly under V stress. In conclusion, V at a low level (10 mg L−1) enhanced sweet potato growth, and a higher level of V treatment (25, 50, and 75 mg L−1) had a deleterious impact on the growth, physiology, and biochemical mechanisms, as well as stomatal traits of sweet potato.
