Note. Each experiment was performed in triplicate. Dashes mean the death of explants. 1 – confidence interval based on student t-distribution at a significance level of 0.05; 2 – the values in the column marked with the same lowercase letters (a, b, c) do not have a significant difference at the 5% significance level (P≤0.05) according to the t-student test
