Screening bicarbonate-tolerant genotypes is an environmentally-friendly and long-term effective strategy to cope with bicarbonate-induced chlorosis in fruit crops grown on calcareous soils. We investigated eleven genotypes from four kiwifruit species (Actinidia chinensis, A. macrosperma, A.

Here we compared the differences of kiwifruit plants between -Fe and +Bic in: (1) the traits of Fe uptake and translocation within plants, (2) Fe forms in roots, and (3) some acidic ions and metabolites in roots. The concentration of Fe derived from nutrient solution (Fedfs) in roots was less reduced in +Bic than -Fe treatment, despite similar decrease in shoots of both treatments.
