Investigations into nutritional disorders causing chlorosis of Groundnut (ArachiHypogaea L.) At ICRISAT center

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 extractableiron 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 foranalysis because chlorosis usually occurs only in the young leaves, and preliminary testing showed that extractable iron contents were lowest in the youngest leaves
