“…Torun et al (2006) evaluated genotypic variation in tolerance to B toxicity in 70 durum wheat (Triticum durum) genotypes and found that there was no relationship between shoot B concentrations and relative decreases in shoot dry weight caused by B toxicity, but the most B-sensitive genotypes generally had much lower amount of B in shoot than the genotypes showing higher tolerance to B toxicity. Similar results were also shown in bread wheat (Triticum aestivum; Kalayci et al, 1998) and in barley (Hordeum vulgare L; Mahalakshmi et al, 1995;Torun et al, 2003): The tolerant cultivars maintained high levels of B in shoots or/and roots. It was further speculated by Kaur et al (2006a) that formation of B-polyol complexes in the vacuoles would be an effective way of storing B without damage to cellular metabolism.…”

“…However, the mechanism may be associated with the inherent ability to tolerate excessive B concentration in plant tissues. It was suggested by several studies that the internal compartmentation of B in vacuoles is a plausible explanation for B tolerance (Torun et al, 2003(Torun et al, , 2006Mahalakshmi et al, 1995). Torun et al (2006) evaluated genotypic variation in tolerance to B toxicity in 70 durum wheat (Triticum durum) genotypes and found that there was no relationship between shoot B concentrations and relative decreases in shoot dry weight caused by B toxicity, but the most B-sensitive genotypes generally had much lower amount of B in shoot than the genotypes showing higher tolerance to B toxicity.…”

Field observations indicate that boron (B)-toxicity symptoms may occur in citrus plants from inappropriate foliar spraying or overfertilizing with B especially under low-rainfall conditions, where B can accumulate to levels that become toxic to plant growth. Previous work has indicated that different rootstocks can greatly influence the scion's tolerance to B toxicity, however, little is known about the response of different citrus scion-rootstock combinations to excess-B conditions. In the present study, we investigated the effects of excess B on plant growth, gas exchange, B concentration, and distribution of four scion-rootstock combinations, Newhall and Skagg's Bonanza navel orange (Citrus sinensis Osb.) scions grafted on Carrizo citrange (C. sinensis L. Osb. × Poncirus trifoliata L. Raf.) and Trifoliate orange (Poncirus trifoliata L. Raf.) rootstocks. One-year-old plants of the four scion-rootstock combinations were grown for 183 d in sand-perlite (1 : 1, v/v) medium under greenhouse conditions. The plants were irrigated with half-strength Hoagland's nutrient solution containing two B concentrations, 0.25 (control) and 2.50 (excess B) mg L -1 . It was found that, apart from the combination of Newhall grafted on Carrizo citrange, the dry weights in various parts of the other three combinations were reduced by the excess-B treatment. Furthermore, the plants of Skagg's Bonanza grafted on Carrizo citrange showed the highest growth reduction amongst the four scion-rootstock combinations. In most cases, the greater reductions in dry weight were found in roots as compared to the other plant parts under excess-B conditions, indicating that roots were more sensitive to B toxicity than the other tissues. In the case of Newhall plants grafted on Carrizo citrange, the entire plant growth was increased by excess-B treatment. Boron concentrations in all plants parts increased significantly by increasing the B supply in the nutrient solution. Leaves were the dominant sites of B accumulation and showed the greatest increase in B concentration compared to the other plant parts, as B concentration in the nutrient solution increased. Our results indicate that the combination of Newhall grafted on Carrizo citrange was more tolerant to B toxicity, while the combination of Skagg's Bonanza grafted on Carrizo citrange was relatively more sensitive to B toxicity, in comparison with the other scion-rootstock combinations. However, Newhall plants contained more B in leaves and in roots than Skagg's Bonanza plants when they were both grafted on Carrizo citrange, indicating that the mechanism underlying such great differential growth responses of the two scion-rootstock combinations to B toxicity may not be associated with B exclusion from roots or reduced translocation of B to shoots. Furthermore, B distribution in different plant parts implied that the mechanism was also unlikely related to altered distributions of accumulated B in plant tissues. However, inherent ability to tolerate excessive B concentration in plant tissues...

“…Screening techniques previously used to identify B tolerance in germplasm include field screening (Torun et al, 2003) and controlled environment screening using both soil-based and solutionbased methods (Campbell et al, 1998) (Chantachume et al, 1995). High field spatial variability in the distribution of soil B in southern Australia (Nuttall et al, 2003b) makes field screening risky and difficult to interpret.…”

Response of lentil (Lens culinaris) germplasm to high concentrations of soil boron

For lentil production to expand further in Australia, adaptation to the less favourable soils of the low to medium rainfall zones is required. To improve adaptation to these regions, varieties are required with increased tolerance to soil constraints such as high concentrations of boron (B), salinity and sodicity. To evaluate the range of B tolerance in lentil germplasm, 310 lines were screened in soil with a high concentration of B and tolerance was assessed at the seedling stage. A wide range in response to high concentrations of soil B was observed in the germplasm tested. Current Australian varieties were generally very intolerant to high concentrations of soil B. High levels of B tolerance was identified in germplasm originating from Afghanistan and Ethiopia. A subsequent experiment comparing lentils with different levels of B tolerance found that tolerant accessions (ILL213A and ILL2024) produced greater above and below ground biomass than intolerant accessions. The tolerant accessions had no significant yield loss under a high B treatment (extractable B = 18.20 mg/kg) compared to the control treatment (extractable B = 1.55 mg/kg). The large improvement in B tolerance, at soil concentrations typical of those found in the target regions, suggests there is potential to improve the tolerance level of adapted varieties and expand lentil production areas to regions with higher concentrations of soil B.
