“…Toxicity symptoms were less visible on plants inoculated with mycorrhiza compared with non-inoculated plants. Contrary to our results, Manchanda & Sharma (1991) reported that increasing B toxicity symptoms in wheat occurred in all treatments having similar or low total shoot B concentrations. There is currently no available explanation for these contrary findings.…”

A greenhouse study was conducted to investigate the effect of mycorrhiza on wheat (Triticum durum) boron (B) uptake under excessive B concentrations. Three levels of B (0, 3, and 6 mg B litre -1 ) were added to pots with or without mycorrhiza. Plant nutrients were added as Hoagland nutrient solution. In general, additions of B with or without mycorrhiza decreased wheat relative yield and increased shoot and root B concentrations. B concentrations in shoots ranged from 30.8 to 589 mg kg -1 . The highest shoot B concentrations were with the highest B treatments (6 mg B litre -1 ), whereas the lowest concentrations were in the control (0 mg B litre -1 ). Mycorrhiza inoculation significantly improved relative yield of unstressed (control) plants, but those increases in relative yield of Bstressed plants were not significant. In general, mycorrhiza inoculation decreased shoot and root B concentrations and uptake. Wheat growing at high B concentrations (6 and 3 mg B litre -1 ) with or without mycorrhiza showed leaf edge burning and necrosis compared with control treatments. The data suggested that mycorrhiza infection can prevent plants from an excessive concentration and uptake of B although that did not improve plant yield. Further evaluation is needed for the effects of mychorriza inoculation on B toxicity.

“…Although moderate and high levels of salinity did not significantly affect B content in aerial part, root, or whole seedling, a finding also reported by Manchanda and Sharma (1991), the lowest dose of NaCl significantly increased B to a degree similar to that seen for N, P, K, Fe, and Mn.…”

Sunflower seeds (Helianthus annuus L., cv. Dwarf) were grown with distilled water only or increasingly saline solutions (NaCl) to determine the influence of salinity on seedling growth and on the distribution of mineral nutrients obtained exclusively from cotyledons. Seedling growth was decreased by moderate (50mM) and high (l00mM) concentrations of NaCl in the growth solution. Salinity generally decreased mineral transport (especially Fe, Mn, Mg, and Ca) from seed to seedling, except for K. Transport of Fe, Mg, and Ca to the aerial part was also markedly reduced.

“…The boron toxicity symptoms had been recently observed in chickpea [1], wheat [2,3], eucalyptus [4] and in stems of Prunus rootstocks [5]. The mechanism of B toxicity is still a matter of speculation.…”

ab s t r ac tSignificant decrease of boron concentration during seawater desalination is one of the more difficult, consuming and expensive tasks. Average boron concentration in the Mediterranean Sea is 4 mg/l, and due to heavy use of wastewater in irrigation the Israeli Water Authority (Ministry of Health) demands boron reduction to 0.4 mg/l maximum. The current boron removal procedure is based on two-pass reverse osmosis (RO) membrane treatment that requires pH adjustment to dissociate boric acid into borate ion. The operation is expensive, energy consuming and calls for cheaper and reliable alternatives. The current research was initiated to explore the abilities of electroflocculation (EF) to remove boron from seawater. The EF experiments were performed under batch electro-chemical reactor conditions with iron electrodes. Settling time and pH of the solution were selected as two main independent parameters. The obtained results suggest that significant boron reduction can be achieved without membrane separation technologies. The obtained drop from 4.2 to 0.8 mg/l boron after 10 min EF and 60 min sedimentation suggests that RO can be applied as a polishing stage only, needed to achieve the goal of 90% B retention. At the same time, the average 80% boron retention achieved by EF/sedimentation is encouraging and can be viewed as a valuable alternative to currently applied RO-based technology. The studies were performed on seawater from the Palmachim beach (near Rishon-Le-Zion, Israel) and were an important step in detection of possible boron removal mechanisms.
