High-carbonate soils are a serious limiting factor for citrus growth because they limit the availability of several micronutrients, particularly iron (Fe). The usual solutions to micronutrient problems are to either not plant in such soils or use expensive chelates or use low-Fe stress tolerant rootstocks. The objective of the study was to screen a broad range of citrus genotypes for tolerance to low-Fe stress. Plants of 26 Citrus and closely related genotypes were assayed for their ability to reduce Fe3+ as a measure of their tolerance to Fe-deficiency stress. Three-month-old seedlings were grown for 2 to 3 months in nutrient solution without Fe. White root tips were periodically harvested and tested for their Fe reduction capacity. Genotypes with the largest Fe reduction responses were Volkamer and Eureka lemon, Etrog citron, sour orange, and Rangpur. |
