Differential iron chlorosis of oat cultivars ‐ a review

摘要: Abstract Markedly different iron chlorosis symptoms were observed among “winter” oat genotypes in field trials at Beevllle, Texas, during the 1975 and 1976 production seasons. An cultivar showing most severe one having no apparent subsequently grown several iron‐deficient soils greenhouse controlled‐environment nutrient‐solution cultures to more critically study these Fe‐stress responses. TAM 0–312, susceptible cultivar, exhibited Fe Texas experiments had a very dramatic response soil treatment with either chelated or powdered metallic iron. In contrast, “chlorosis resistant” Coker 227, experiments, showed little compounds. controlled environment studies U.S.D.A.
