Effects of Nitrogen on Zinc Uptake, Accumulation and Partitioning of Wheat

Abstract:

Effects of nitrogen on uptake, accumulation and partitioning of zinc throughout the development of wheat were studied under pot-culture conditions. The results showed that under low zinc application (0.2 mg kg-1) the grain zinc content increased by 140% when nitrogen fertilizer increased from 50 mg kg-1 to 150 mg kg-1. Under high zinc application (5 mg kg-1) the grain zinc content increased by 61%. Increasing nitrogen application under low zinc fertilizer, the grain zinc mainly comes from the root zinc uptake. While increasing nitrogen application under high zinc fertilizer, the grain zinc mainly comes from the straw zinc remobilization.
