Summary
Soil solution Zn, Cu, Mn and Fe concentrations which were monitored throughout the growing season were found to be representative for flooded rice culture. Plant Zn, Cu, Mn and Fe contents of top, middle and bottom leaves as well as whole plants were also measured periodically throughout the growing season. These data were found to be within reported ranges for rice plants grown on flooded soils. Simple regression analyses were performed between plant micronutrient contents for each plant part sampled and the corresponding soil solution values. Results showed that the most promising portions of the rice plant to sample for accurate assessment of plant response to changes in soil solution micronutrient concentration as a function of time are as follows: (a) for Zn, bottom leaf; (b) for Cu, top or bottom leaf, whole plant; (c) for Mn, top leaf and (d) for Fe, bottom leaf or whole plant. re]19750915
