Jirong Cao; Chunzhen Cheng; Junjie Yang; et al. Scientific Reports 2015. doi:10.1038/srep14675

Other claims from this paper (4)

Intervention effect HLB-pathogen infection decreased P resorption efficiency in C. reticulata relative to healthy plants in summer.

Observation Fruit quality at harvest was not seriously affected, apart from some loss of color
Association Iron content of the juice was about proportional to iron content of the leaves
Intervention effect Fruit size was the same or slightly larger in iron-deficient trees
Observation Twig dieback was observed as a symptom of iron deficit that caused loss of fruit yield
