Morphological parameters of AR formation in tissue culture plantlets of Malus prunifolia. Tissue culture plantlets were divided into five groups: Control, MT, MT0–2, MT2–5, MT5–20. The number of ARs, and their length, surface area and volume were measured in the five treatment groups. Values represent the mean ± SE for three biological replicates; letters indicate significant differences between means (P < 0.05)
