“…It indicates increasing root dry weight in Mn toxicity. This study is also in line with previous study (Kuswantoro 2015b) that reported some genotypes have higher root dry weight in Mn toxicity than in control, but contrast to studies of Izaguirre-Mayoral and Sinclair (2005), Hadjiboland et al (2008) and Khabaz-Saberi et al (2009) that reported decreasing root dry weight was in high Mn concentration. Increasing root diameter (Junior et al 2009) and/or root thickening may be the cause in increasing of root dry weight.…”

Abstract. Kuswantoro H. 2016. Differential response of roots growth of soybean germplasm under low pH and manganese toxicity. . Most of Indonesia dry land are covered by acid soil. The growth and development of the plant in this acid soil cope with low pH and micronutrients toxicity. The objective of this research was to study the response of root growth of soybean germplams to low pH and manganese toxicity. Nine soybean germplasm were treated in aquadest with pH 7 as control, aquadest with pH 4, and 75 ppm Mn with pH 4 in Seed Laboratory of Indonesian Legume and Tuber Crops Research Institute, Malang, Indonesia. Results showed that root length, number of lateral roots, root dry weight were lower in low pH and Mn toxicity than in the control. Shoot dry weight, hypocotyl length and epicotyl length were not influenced by low pH and Mn toxicity. Some genotypes showed increasing root length in low pH, and increasing number of lateral roots and root dry weight in Mn toxicity. Based on the acid soil adaptation index (ASAI) on root length, MLGG 0493 and MLGG 0496 showed the highest value index in three comparative conditions. The genotype of MLGG 0496 also showed the highest ASAI value on numbers of lateral root in three comparative conditions. MLGG 0494 achieved the highest ASAI value of root dry weight. However, the use of root dry weight as a criterion in soybean adaptation in low pH and Mn toxicity should be studied further because the tolerance is not just in increasing root dry weight as a result of root thickening.

“…The highest decreasing was shown by MLGG 0025 that achieved 21.87%, while other genotypes had relatively low decreasing percentage. Some researcher also reported similar results, where increasing solution Mn concentration decreased shoot dry weight (Izaguirre-Mayoral & Sinclair, 2005;Khabaz-Saberi et al, 2009). Some genotypes did not experience seedling dry weigth decreasing.…”

In excessive manner, mangan (Mn) as an essential nutrient can be toxic to the plant. This phenomenon often occurs in acid soil. Hence, it is needed gene resources to develop plant in acid soil. The soybean germplasm tolerance to Mn toxicity was tested in seed laboratory, using two factors experimental design. The first factor was Mn toxicity containing two treatments (1) 0 ppm Mn in pH 7 as control, and (2) solution concentration of 75 ppm Mn in pH 4. The second factor was 14 accessions of soybean germplasm. Results showed that generally root characters decreases while shoot characters increased in Mn toxicity condition. However, some genotypes showed different performance. There was one genotype having the highest root dry weight in Mn toxicity condition, i.e. MLGG 0091. The highest root dry weight in this genotype was also supported by the root length and number of roots. MLGG 0091 was also capable to increase the length epicotyle that contribute to the increase in seedling dry weight. Therefore MLGG 0091 can be used as a gene source for tolerance to Mn toxicity.

“…The optimization of screening techniques and identification of genotypic variation for tolerance to ferrous Fe (KhabazSaberi et al, 2010a) and Mn (Khabaz-Saberi et al, 2010b) in the Australian wheat germplasm provided the required tools (wheat genotypes with and without tolerance of Al, Mn, or Fe) to quantify the effect of individual ion tolerance and also to test the hypothesis that performance in waterlogged acidic soils may be improved by enhanced tolerance to high-to-toxic ion concentrations. The support for that hypothesis would justify pyramiding multiple ion tolerances through plant breeding into current wheat germplasm as an environmentally friendly alternative to, or at least supplementation of, the current agronomic approach of adding lime and installing drainage in acidic soils prone to waterlogging.…”

Waterlogging results in high shoot concentrations of iron (Fe), aluminum (Al), and manganese (Mn) in wheat grown in acidic soil. The verification of this observation in several acidic soils, development of screening techniques, and identification of genotypes differing in tolerance made it possible to test whether tolerance of ion toxicities improves performance of wheat in waterlogged acid soils. Six wheat varieties selected for tolerance/intolerance of Al, Mn, and Fe were grown in three acidic soils (pH CaCl2 4.1-4.3) with or without waterlogging for 40 d. In terms of relative shoot dry weight, Al-, Mn-, and Fe-tolerant genotypes tolerated waterlogging better, outperforming intolerant genotypes by 35%, 53%, and 32%, respectively, across the soils. The Al-tolerant genotype had up to 1.8-fold better root growth than the intolerant genotype under waterlogging. Waterlogging increased DTPA-extractable soil Mn (71%) and Fe (89%), and increased shoot Fe (up to 7.6-fold) and Al (up to 5.9-fold) for different genotypes and soils. The Al-tolerant genotype maintained lower tissue concentrations of Al as compared to intolerant genotypes during waterlogging. Waterlogging delayed crop development but distinctly less so in the tolerant than in the intolerant genotypes, thus jeopardizing the capacity of intolerant genotypes to produce yield in Mediterranean climates with dry finish of the season. Pyramiding multiple ion tolerances into current wheat varieties with desirable agronomic and quality characteristics to enhance their performance under waterlogged acid soils should be considered.
