Effect of Zn application rate on the Zn concentration in the shoot (A) and pollen viability (B) in maize at the tasseling (VT) stage, and the relationship between pollen viability and Zn concentration in the shoot at the VT stage (C). The pollen viability was scored according to staining level (pollen with bold red colour as viable and colourless as nonviable). The percentage of pollen viability was determined as the ratio of the number of viable (energetic) pollens to the total pollens number. Values are the average ± SE of four replicates. Means with the same letters are not significantly different at P < 0.05 according to Fisher’s least significant difference (LSD) test. ** P < 0.01.
