Abstract
Zinc (Zn) deficiency is the most widespread micronutrient disorder in rice. The objectives of the present study were to investigate the effect of Zn application and root pruning on Zn absorption by transplanted rice. Pots were arranged in a factorial complete randomized design with three replicates, which comprised of 7 rates of Zn (0, 20, 40, 80, 160, 320 and 640 μg Zn kg -1 air dry soil), with 0 and 50 % root pruning. The obtained data were analysed statistically by the analysis of variance. The results showed that the relative Zn absorption rate were closely related to the dry weight of shoot and root. Root pruning had a lower rates of Zn absorption than those of without pruning. Therefore, root pruning impaired plants growth and eventually reduced dry matter production. In conclusion, root recovery and root function of transplanted rice were sluggish by low Zn supply and root pruning, and increasing Zn application could not compensate for the pruned roots.
