| Three weeks old Commelina was cultivated in Hoagland solution with or without $(pm{100mu{M};Cd^{2+}$ and with $100mu{M};Cd^{2+}+100mu{M; SA)$ for 4 days. The contents of $Cd^{2+}$ and nonprotein-SH synthesis in roots and isolated epidermal strips were measured. In the treatment of $Cd^{2+}$, the concentration of $Cd^{2+}$ was $98mu{M};Cd^{2+}$/g.fr.wt and it was 6 times higher than that of control. $Cd^{2+}$+SA increased 1.2 times higher concentration of $Cd^{2+}$ than that of the treatment ofTEX>$Cd^{2+}$ alone. In the treatment of TEX>$Cd^{2+}$, nonprotein-SH also increased 2 times higher than that of the control. TEX>$Cd^{2+}$ + SA increased 2 times higher concentration of nonprotein-SH than that of the treatment of TEX>$Cd^{2+}$ as well. In case of isolated epidermal strips, the response was similar with the roots. Therefore, it suggest that the effect of salicylic acid on the accumulation of TEX>$Cd^{2+}$ and nonprotein-SH synthesis in roots, and isolated epidermal strips was related with an increase of the membrane permeability by SA and that SA may be positively involved in the process of nonprotein- SH synthesis. |
