“…This sort of stress accumulates ROS (potent oxidative species), such as superoxide radicals, hydroxides, and hydrogen peroxides (H 2 O 2 ). These, in turn, cause oxidative stress on plant biological molecules, resulting in cell death (Nejad and Etesami, 2020). Our results corroborate those of Lima et al (2013), which showed that B doses above 1.5 kg ha -1 decrease common bean seed vigor due to toxicity effects.…”

“…It is noteworthy that high B concentrations cause deleterious effects on plant growth and development. Furthermore, B toxicity inhibits germination of several plant species, reduces root and stem growths, inhibits cell expansion, and affects photosynthesis, causing damage to thylakoid assembly and thus reducing CO 2 absorption (Uluisik, Karakaya, & Koc, 2018).…”

Boron (B) deficiency is commonly found in tropical crops, among which sorghum stands out for its limited yield under B shortage. However, as a micronutrient, the range between its adequate and toxic levels is narrow, thus fertilization should be cautiously applied. Our goal was to evaluate the physiological and physical quality, as well as early performance, of grain sorghum seedlings under different B doses applied via seeds. Treatments consisted of six doses of boric acid (0.0, 2.5, 5.0, 7.5, 10.0, and 12.5 g Kg-1 seeds) plus a control (uncoated seeds). Boron doses were applied to seeds by coating, in which dolomitic limestone and glue were used for pellet formation. Coated seeds were assessed for physical, physiological, and nutritional characteristics in the laboratory, and early seedling performance was evaluated in a greenhouse. Seed tests were carried out in a fully randomized design, while seedling evaluations were carried out in a randomized block design. Boron application to seeds had no significant effect on seed physical characteristics, despite increases in coated seed sizes. Boron doses had a negative effect on the length and dry mass accumulation of both plant shoot and root. Seed-applied B accumulated mainly in roots and significantly interfered with Ca and Mg accumulations in sorghum seeds, shoots, and roots.

“…Boron, as one of the essential micronutrients in plants, directly or indirectly participates in a variety of physiological and biochemical processes in plant growth and development [30]. Boron has very low mobility in tomato plants [8,31], and the optimum boron level varies with different tomato varieties, ranging from~0. [17,20,21].…”

The effect of application methods with different boron levels on the growth, fruit quality and flavor of tomato (Solanum lycopersicum L., cv. ‘Jinpeng No.1’) were investigated under greenhouse conditions. Seven treatments used included two application methods (leaf and root application) with four boron levels (0, 1.9, 3.8 and 5.7 mg∙L−1 H3BO3). Experimental outcomes revealed that both application methods significantly increased net photosynthetic rate and chlorophyll content, and stabilized leaf structure of tomato. Leaf spray of 1.9 mg∙L−1 H3BO3 was more effective at improving plant growth and photosynthetic indices in tomato compared to other treatments. Additionally, root application of 3.8 mg∙L−1 H3BO3 resulted in better comprehensive attributes of fruit quality and flavor than other treatments in terms of amounts of lycopene, β-carotene, soluble protein, the sugar/acid ratio and characteristic aromatic compounds in fruit. The appropriate application of boron can effectively improve the growth and development of tomato, and change the quality and flavor of fruit, two application methods with four boron levels had different effects on tomato.

The main purpose of this experiment was to investigate the effects of salinized water with boric acid and sodium chloride (NaCl) on seed germination and seedling establishment of wheat. The following treatments were applied: Boric acid solution (0, 40, 240, and 480 μM) and NaCl solution (0, 50, 250, and 1,000 μM) were combined to produce 16 different solutions. The highest germination percentages were found in distilled water. Shoot length and root length of wheat were reduced by increments of all boric acid treatments in both saline solution and distilled water, but the decrease in shoot length due to boron toxicity was significant more pronounced in saline conditions. The greatest shoot and root lengths were observed in the control treatment (distilled water), and the smallest lengths were observed in the highest boric acid treatment (480 μM). Shoot and root dry weight also decreased with increasing boric acid.The averages of variables were also significantly affected by salinity solutions, but to a greater extent than under the influence of boric acid. It is concluded that wheat plants cannot tolerate salinized water with boric acid and NaCl during the germination stage.
