Impact of boric acid and saline water irrigation on germination and seedling establishment of wheat*

Abstract

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.

“…Due to the shift in water demand from agricultural to household uses brought on by population growth, agriculture is an important sector that will be adversely affected by water scarcity. Furthermore, in order to meet the increased demand for irrigation, lowquality water, particularly saline water, will be used more frequently [2]. Abiotic stress is one of the most critical challenges facing agriculture today.…”
