The effectiveness of microspore embryogenesis (mean number of embryo-like structures produced per spike of the donor plant ± SE) in isolated microspore cultures of winter triticale as the effect of various pre-treatments of tillers. The mean from at least three biological replications (isolations) ± SE. Axis Y is in the log scale. The asterisk symbol ‘*’ indicates values that are statistically different (p ≤ 0.05) from control (LT pre-treatment of tillers). LT low temperature pre-treatment of tillers (21 days at 4 °C); LT + 3–8d GSH low temperature pre-treatment of tillers (21 days at 4 °C) combined with short GSH pre-treatment (0.3 mM GSH applied 3–8 days before microspore isolation); LT + GSH low temperature pre-treatment of tillers (21 days at 4 °C) combined with long GSH pre-treatment (0.3 mM GSH applied 21 days before microspore isolation)
