Nitrogen effects and genotypic variation in Cd absorption, translocation, and chemical forms in wheat.

ABSTRACT:

Introduction

Reasonable nitrogen (N) and low grain cadmium (Cd) accumulators can effectively reduce grain Cd content in wheat; however, the underlying mechanism remains unclear.

Methods

This study aimed to investigate N effects and genotypic variation in Cd absorption, translocation and chemical forms in low (Chuannong30) and high (Chuanmai88) grain-Cd-accumulating wheat. Pot experiment was arranged in a completely randomized design consisting of two-factors: two soil Cd treatments and six N levels.

Results and discussion

The results showed that both genotypes can be grown safely in low-Cd soil under N fertilization rate of 180 kg·ha^-1, the low grain-Cd accumulating genotypes can be grown in high-Cd soil under fertilization rates < 135 kg·ha^-1, w
