Abstract

Identification and regulation of distribution of mineral nutrients between source and sink members is beneficial in improvement of growth and development of fruit trees. The aim followed in this study was an evaluation of the effects of urea and ZnSO₄ on storage and translocation of nitrogen and zink in the leaf and fruits of pomegranate cv ‘Rabab-e-Neyriz’. In 2009, ZnSO₄ (0.0, 0.3%, 0.6%) was sprayed on young fully expanded leaves (<20 days) while urea (0.0, 1.5%, 3%) sprayed two weeks following full bloom. A factorial experiment based on RCBD of three replications was employed and comparison of means done through Duncan Multiple Range Test at P<0.05 and P<0.01. Results revealed that urea treatments significantly decreased N content in leaf, while 3% urea increased N content in fruit peel. Both concentrations of ZnSO₄ significantly increased Zn in the leaf and fruit. The higher concentration of ZnSO₄, caused increased translocation of Zn between leaf (sprayed) and fruit (non-sprayed).
