Abstract

The monitoring of the iron content of leaves in the field showed that chlorosis was associated with low levels of o-phenanthroline extractable iron (an estimate of ferrous iron). Similarly, four breeding entries exhibiting marked chlorosis contained significantly lower extractable iron than four entries in which chlorosis was only mild or not evident. The extractable iron contents of the buds or first unfolded leaf of chlorotic plants were always less than 6 fi/g fresh tissue. ·The youngest leaf tissue was selected as the most appropriate plant part for analysis because chlorosis usually occurs only in the young leaves, and preliminary testing showed that extractable iron contents were lowest in the youngest leaves...
