Note: df and MS represent degrees of freedom and mean square, respectively. B, Al, P, and C represent the sum of block, aluminum, phosphorus, and clone, respectively. RDW, SDW, LDW, and R, represent root dry weight, stem dry weight, leaf dry weight, and root/shoot ratio, respectively.

* Significant difference (0.01 < P < 0.05).

** Highly significant difference (P < 0.01)
