Effect of Si and Cd on root fresh weight (RFW) (g plant−1), root dry weight (RDW) (g plant−1), root length (R.L.) (cm), root diameter (R.D.) (mm), root volume (R.V.) (cm3), root tips (R.T.) (no. of lateral roots) contents in the roots of wheat plants. The values are expressed as the mean ± S.D. (n = 3). The different superscript letters within a column indicate significant differences at P < 0.05.
