“…(1990) described considerable problems with using leaf or shoot analyses to diagnose boron toxicity in barley and wheat due to the pattern of boron distribution in vegetative tissue and the effects of differential transpiration rates and rain on accumulation of boron by plants . Nable and Moody (1992) reported a decrease in boron concentration and content of whole shoots and young leaves of wheat harvested from a field trial conducted in a high boron soil . They concluded that foliar analysis is unreliable for diagnosing boron toxicity due to the change in boron concentration by rainfall .…”

A new screening technique for tolerance to high concentrations of boron, namely a filter paper technique, and a soil experiment were compared to investigate the response of wheat genotypes known to differ in tolerance to high concentrations of boron .Under high boron concentrations in filter papers, the more tolerant genotypes had significantly longer roots than those of the more sensitive genotypes . There was no significant correlation between the root lengths at the control treatment and the other three boron treatments (50, 100, 150 mg B L -1 ) . Thus, the differences in root lengths at the high boron treatments could not be attributed to inherent differences in root growth but to the genetic variation in response to high boron concentrations among varieties .Root lengths at the three boron treatments in filter papers were highly significantly correlated with the three characters determined for plants grown in soil containing high levels of boron, namely the concentrations of boron in the shoots, plant dry weight and plant symptoms, indicating that root length could be used as a selection criterion in a genetic study or breeding program for boron tolerance .

“…Anderson and Ohki (1972) reported that greenhouse-grown cotton with a leaf blade B concentration of 22 mg kg-1 did not respond to foliar-applied B; however, others reported a positive response in cotton to supplemental B even when leaf B levels were as high as 26 mg kg-1 (Anderson and Boswell, 1968). In wheat (Triticum aestivum L.), critical plant B concentrations were dependent on environmental conditions (Nable and Moody, 1992). USDA-ARS, Cotton Physiology and Genetics, P.O.…”

“…In barley (Hordeum vulgare L.), toxic levels ofB in leaves varied with vapor pressure deficit (Nable et al, 1990). In wheat, the leaching ofB from leaves by rainfall (Nable and Moody, 1992) greatly reduced leaf B concentration, suggesting that a critical concentration might be difficult to establish.…”

Cotton (Gossypium hirsutum L.) is sometimes grown on soils with low B concentration. However, most of the literature regarding the effects of supplemental B on cotton was obtained from obsolete, low‐yielding genotypes rather than modern, high‐yielding genotypes. Therefore, the objective of this study was to determine the effects of soil‐ and foliarapplied B on leaf blade B concentration, boll retention, and lint yield of modern cotton genotypes. In 1991, three genotypes (DES 119, DES 24‐8 ne normal leaf, and DES 24‐8 ne okra leaf) and in 1992, two genotypes (Deltapine 20 and Deltapine 5415) of cotton were grown in the field on a Beulah fine sandy loam (coarse‐loamy, mixed, thermic Typic Dystrochrepts) having 0.11 mg kg−1 hot water extractable B concentration. Treatments included preplant soil and foliar (first flower to end of bloom) B (78% Na2B8O13·4H2O, 20% Na2B4O7·5H2O) applications for seasonal totals of 0, 0.89, or 1.78 (1992 only) kg B ha−1. The lowest rate of foliar‐applied B increased leaf blade B concentration from 25 to 70 mg kg−1 in 1991 and from 54 to 108 mg kg−1 in 1992. In 1992, the highest rate of foliar B applications resulted in a leaf blade concentration of 154 mg B kg−1. Soil‐applied B did not alter leaf blade B concentration in 1991, but slightly increased leaf blade B concentration in 1992 from 54 to 71 mg kg−1. Soil B concentrations were higher during the midseason than the preplant period, suggesting that preplant soil B analysis may not accurately foreshadow soil B supply during the season. Soil B or foliar B applications did not affect boll retention percentage, flower number, or lint yield in either year. Supplemental B did not affect boll distribution in 1991, but in 1992, foliar B applications increased the percentage of fruit on monopodial branches. In both years, supplemental B did not greatly affect fiber properties with the exception that supplemental B increased fiber micronaire reading of Deltapine 20 in 1992. The results suggest that modern cultivars may not always need supplemental B when soil B concentration is moderately low.

“…Because of variation among varieties, new plant genotypes could be developed with higher genetic ability to tolerate B toxicity in soils. Several screening studies have been conducted to determine the extent of genotypic variation in tolerance to B toxicity in different crop species such as wheat Nable and Moody, 1992;Yau et al, 1995;Jamjod, 1996;Kalaycı et al, 1998;Torun et al, 2006), barley (Kluge and Podlesak, 1985;Nable, 1988;Mahalakshmi et al, 1995;Rehman et al, 2006), pea (Bagheri et al, 1992;Avcı and Akar, 2005), tomato (Güneş et al, 2000), groundnut (Lauter et al, 1989), and turnip (Kaur et al, 2004). These studies showed existence of a large genotypic variation in susceptibility to B toxicity.…”

2 Although many states recommend boron (B) fertilizer for many field crops, information about B toxicity of canola is lacking. This experiment was carried out at Central Anatolia, Turkey from 2002 to 2003, to determine genotypic range in B efficiency of eight spring canola cultivars, to identify the B-inefficient cultivars and to identify specific responses. The cultivars were grown under B moderate deficiency (extractable B 0.56 mg kg −1 ) and toxic B applied (15 kg B ha −1 ) conditions. According to the results, seed yield varied significantly among the cultivars and B application decreased the seed yield by 31% on average. Also, toxic B application reduced protein and oil contents similar to seed yield, and increased leaf B concentration in all varieties. This study has shown that leaf B concentration has increased considerably when B is applied to Pactol and Star cultivars, but seed yield of +B and −B has not shown significantly a change. It is possible to say that Star and Pactol-which have not been affected by the toxic B application-are genotypes that are tolerant to B toxicity and may be cultivated at B toxic lands.
