Abstract
Changes in growth pattern of G. F. 305 peach plants as affected by iron deficiency was worked out in sand and water culture experiments. Iron deficiency in peach plants was characterised by interveinal chlorosis of leaves, the mid-rib being comparatively more green than secondary veins. When iron deficient plants were fed with nutrient solution containing labelled iron the distribution of iron tended to follow the pattern of chlorophyl distribution in such leaves. As the chlorosis advanced chlorophyl B decrease more than chlorophyl A. Root growth was less affected than stem and leaves. Iron deficiency lead to cessation of growth of the apical meristem and disturbance in the mechanism of cerelative inhibition. Different branches of a plant showed highly inequal intensities of chlorosis. The most severely affected shoot was generally the central one.
