“…Nawaz et al [15] reported that V application dramatically decreased root traits of watermelon seedlings. Similarly, our previous study revealed that V-treated tomato seedlings impaired root architecture and mineral nutrient uptake [20]. Moreover, in chickpea, higher V concentration considerably decreased root morphological traits, such as root length, volume, surface area, forks, tips, and crossings [21].…”

“…In this research, higher V (20, 30, 40, and 50 mg) concentrations significantly decreased the levels of chlorophyll a, chlorophyll b, and carotenoids in tomato seedlings (Figure 6A-C). In our previous study, V treated tomato seedlings showed a significant decline in pigments content [20]. Similarly, in another study, Sarafi et al [45] reported that boron (100 µM) supplementation remarkably reduced chlorophyll a, chlorophyll b and carotenoids content of pepper seedlings.…”

“…The results of present study revealed that V (20, 30, 40, and 50 mg) supplementation significantly reduced the growth attributes of pepper seedlings (Table 1, Figure 2). In our recent study, Altaf et al [20] observed that V (40 mg) application effectively decreased the growth status (FSW, FRW, DSW, DRW) of tomato seedlings. In another work, higher V concentrations negatively affected the growth of rice and chickpea [12,21].…”

“…Our results stated that V application significantly increased the level of H 2 O 2 in pepper seedlings (Figure 8A). In a recent study, Altaf et al [20] found that V supplementation remarkably enhanced the production of H 2 O 2 in tomato seedling. In another study, under V stress, the level of H 2 O 2 was increased in watermelon seedlings [15].…”

“…Previously, García-Jiménez et al [10] reported that V (5 µM) stimulates pepper growth and development by enhancing biomass production and yield. V negatively affects plant growth in many plant species by hampering the antioxidant mechanisms under its toxicity [15,20]. The reports on the physiological and biochemical response under V toxicity of the pepper plant are still low in number, which warrants further investigation.…”

Heavy metal contamination is one of the current serious environmental and agricultural soil issues, and it is mainly due to anthropogenic activities. Vanadium (V) is found in low concentrations in a wide range of plants and is widely distributed in soils. The current study aimed to determine how pepper seedlings responded to various V concentrations, as well as the detrimental effects of V on growth, root morphological traits, photosynthetic performance, reactive oxygen species (ROS), osmolytes production, antioxidant enzyme activities, and V uptake. Pepper seedlings (5 weeks old) were grown in hydroponic culture with six V levels (0, 10, 20, 30, 40, and 50 mg L−1 NH4VO3). After two weeks of V treatment, low level of V (10, 20 mg L−1) enhanced the growth status, conversely higher V (30, 40, and 50 mg L−1) level reduced the growth. The leaf gas exchange elements, pigments molecules, and root growth characteristics are also affected by higher V concentrations. Moreover, V uptake was higher in roots than in the shoot of pepper seedlings. Similarly, osmolytes content, ROS production, and antioxidant enzymes activities were significantly improved under V stress. Concluding, lower V (10, 20 mg L−1) concentration positively affected pepper growth, and higher V (30, 40, and 50 mg L−1) concentration had a detrimental effect on pepper physiological and biochemical mechanisms.
