The deleterious effects of Mn stress on many species have been studied, mainly concerning biochemical, physiological and growth parameters of plants. However, there are few studies relating the anatomical and ultrastructural changes in response to manganese (Mn) nutritional disorders, This study examined the leaf ultrastructure of Mn-inefficient (IAC-15, Santa Rosa) and Mn-efficient (IAC-Foscarin 31) soybean (Glycine max L.) genotypes in response to three rates of Mn (0.5, 2 and 200 μmol L -1 ) in the nutrient solution. Symptoms of Mn deficiency developed 12 days after transplanting in IAC-15 and Santa Rosa, followed by IAC-Foscarin 31 on the 15 th day. Only IAC-15 and Santa Rosa leaves showed symptoms of Mn toxicity. The Mn concentration in leaves ranged from 8.6 (deficiency) to 886.3 mg kg -1 d.w. (toxicity). There were no changes either in stomata length or stomata number per unit of leaf surface. Cytoplasm disorganization was observed in IAC-15 under Mn-excess. In this case, the cytoplasm was amorphous, densely stained and extensively disorganized, with increased vacuolation. Mn effects were not found in mitochondria and nucleus in any of the genotypes tested. Under all Mn concentrations, many lipid globules were observed in the IAC-15 chloroplasts. There was an increase in the number of plastids as well as in the size of starch grains within IAC-Foscarin 31 chloroplasts as Mn concentration in the nutrient solution increased. Genotypes had marked differences in the ultrastructure organization, mainly in leaf chloroplasts grown under conditions of both Mn deficiency and toxicity (the most sensitive genotype was IAC-15).

“…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.

“…For example, Sliman (1990) reported antagonism between Fe and Zn in soybean. Other studies have found that Fe reduced Mn concentrations in Indian mustard (Hamlin et al, 2008) and in soybean leaves (Izaguirre-Mayoral and Sinclair, 2005), but increased Mn concentrations in soybean shoots. Other authors reported a negative correlation between Zn and Cu (Pearson et al, 2008;Kumar et al, 2009).…”

In a field study, the effect of iron source through foliar as well as basal application was studied on lime induced iron-deficiency chlorosis (LIIC), chlorophyll content, nitrate reductase activity, available Fe and micronutrients in groundnut.The visual chlorotic rating screen of various Fe-efficient and Fe-inefficient cultivars clearly identified Fe-efficient and Fe-inefficient. Tirupati-4 was showing symptoms of chlorosis and was Fe-inefficient. Fe absorption capacity varied among cultivars. Applications of iron increased active Fe content in LGN-2 by 5.6 % and 163.18% in CSMG-84-1 respectively. A significant increase in chlorophyll content (10%) and nitrate reductase (110%) was observed with foliar spray of FeSO 4 . A significant damage of lipid peroxidation was observed in absence of iron which was improved by 37% in Tirupati-4 and 16.67% in CSMG-84-1 by foliar and basal supplementation of Fe, respectively. A strong correlation among the Fe, Mn, Zn and K depicted ionomic interaction with different treatments. Based on the ion absorption capacity and the level of chlorosis, the groundnut genotypes were grouped as tolerant, moderately tolerant and sensitive to iron chlorosis.
