Fig. 6: Effects of dopamine and its derivatives on physiological and biochemical indices of NaCl-stressed tomato seedlings.
From: Chelation and nanoparticle delivery of monomeric dopamine to increase plant salt stress resistance
Images of tomato plants treated with a control, b NaCl, c NaCl+PDA, d NaCl+DA, e NaCl+Zn/DA, f NaCl+EZD, and g NaCl+ODBAC/SL-EZD after 20 treatment cycles; h growth of plant heights (n = 5 independent experiments, bars represent the means ± SD), i root lengths, j number of root tips, and k root surface areas (n = 5 independent experiments, individual data point represents the means. Boxes represent the 25th–75th percentile range, white lines represent medians and whiskers show the minimum-maximum range); l chlorophyll content, m proline, n \({{{{\rm{O}}}}}_{2}^{-}\) activity, and o MDA content of tomato plants treated with NaCl, NaCl+PDA, NaCl+DA, NaCl+Zn/DA, NaCl+EZD and NaCl+ODBAC/SL-EZD after 20 treatment cycles (n = 3 independent experiments, bars represent the mean ± SD). Different letters indicate statistically significant differences based on one-way ANOVA and Tukey’s HSD test analysis, P < 0.05.
