Table 2.
Effect of Tre on shoot length, root length and root volume in maize seedlings under saline and low P stress. Each value of data represents mean of three independent experiments, each replicated three times. Values within a column with different letters are significant at p ≤ 0.05 applying least significant difference (LSD) test.
