Table 1.
Dry weight percentage (DW%), moisture content percentage (MC%) and relative water content (RWC) in the cotyledonary leaves of R. communis after 6 day of exposure to CuSO4 (80 and 160 μM) and cytokinin (KIN and BAP) treatments in Hoagland’s nutrient medium. Values are the mean ± SE of three independent experiments. Different alphabetical letters indicate significant differences between treatments according to one-way ANOVA (Duncan’s test p ≤ 0.05).
