Figure 4. Means ± 1 standard error of the plasticity of physiological parameters in response to cold treatment. (A) Plasticity of superoxide anion (O2·-), hydrogen peroxide (H2O2), anthocyan (Anth), chlorophyll (Chl) and flavonol (Flav) concentrations and the nitrogen balance index (NBI). Asterisks indicate the significance of the Student’s t-test between the cold and control treatments *: p < 0.05, NS: non-significant, ND: Not determined. Means ± 1 standard error of the plasticity of fatty acid contents in (B) leaves, (C) hypocotyls and (D) roots ordered according to the biosynthetic pathway (i.e., palmitic, stearic, oleic, linoleic and linolenic acids). Asterisks indicate that the confidence interval for plasticity differs significantly from 1. Plasticity values less than 1 indicate reduction caused by the cold treatment, while values and greater than 1 indicate induction. Corresponding experimentations for (B, C and D) was 20CA02, 19CA04,19CA01,20CA01, 20CA03, 22CA01 were add to measure trait on (A).
