Abstract
The effect of iron chlorosis on proteins, photosynthetic pigments and acyl lipid composition of adult field grown peach tree leaves has been studied.
No differences in the samples have been found between the iron extracted by
,‘ – dipyridyl (active iron) and total iron analysed by atomic absorption spectrometry, both analyses are good determinations to detect iron chlorosis.
The levels of proteins, photosynthetic pigments and acyl lipids were reduced under iron chlorosis, although the concentrations of proteins and polar lipids per chlorophyll unit were higher in the chlorotic peach tree than in the control.
