Figure 1.

Effect of exogenous kinetin on the electrolyte leakage index in the leaves of coffee plants under optimum and cold stress conditions. Optimum temperature, 25/20 °C, whereas cold stress conditions, 12/12 °C. Kin, kinetin. Different capital letters, (A, B) denote statistically significant differences between the parameter means within temperature treatments, whereas different small letters, (a, b) denote statistically significant differences for the parameter means within kinetin treatments (p < 0.05, Newman–Keuls test). Means are a replicate of three independent samples (n = 3). Error bars represent standard deviation of the mean.
