| Popis: | Iron (Fe)‐deficiency chlorosis is widespread in numerous crops grown on calcareous soils and results in significant yield losses. Examples of affected crops are soybean (Glycine max L.), chickpea (Cicer arietinum L.), peanut (Arachis hypogaea L.), dry bean (Phaseolus vulgaris L.), tomato (Lycopersicon esculentum Mill.), oat (Avenae sativa L.), wheat (Triticum aestivum L.), sorghum [Sorghum bicolor (L.) Moench], corn (Zea mays L.), rice (Oryza sativa L.), and various fruit species. Other than with high return fruit crops, the problem is not economically solved with fertilizer application. A more reasonable solution is the introduction of genotypes which are resistant to Fe‐deficiency chlorosis development (physiologically ‘Fe efficient')‐ Field selection for resistant cultivars is complicated by heterogeneous soil and environmental conditions, and breeding programs implementing these techniques are slow and have reached a plateau. The physiological responses to Fe‐deficiency stress include release... |
