Abstract

A study on iron uptake in sugarcane and role of ethylene was conducted on sixty days old micropropagated plantlets of sugarcane cv. CoPant 84212 and CoPant 90223. Ethylene was estimated in sugarcane plants grown in different concentrations of iron in MS medium. The highest concentration of ethylene was produced by plantlets grown in iron free medium. Increasing concentration of iron in the medium increased the uptake of iron and manganese but decreased zinc and copper uptake. Iron content in roots was higher than the leaves. Large number of root hairs developed on the roots of plantlets grown in iron deficient medium.
