Figure 2.

Bar charts depicting the effects of different plant hormone treatments on roots and leaves. (A) Metallothionein content, (B) Non-protein thiol content, (C) Phytochelatins content, and (D) Glutathione content are shown. Each chart compares various treatments like CK, JA20, SA50, etc., for roots (orange bars) and leaves (green bars), with statistical significance indicated by asterisks. Error bars represent variability, and different letters denote statistical differences among treatments.

Effect of plant hormone treatment on root and leaf content of metallo-thioneins (A) non-protein thiol (B) phytochelatins (C), and glutathione (D). Data are mean ± SD (n=4). Asterisks (*) denote overall significant differences (**P < 0.01; ***P < 0.001). Values with different lowercase letters in the same column indicate significant differences among treatments at the 0.05 level.
