The effect of low temperature (LT) and glutathione (LT + GSH) treatments on embryo-like structures (ELSs) production in DH lines of triticale (× Triticosecale Wittm.) with different embryogenic potential. a–h Isolated microspores of the recalcitrant DH19 line after LT (a–d) and glutathione (LT + GSH; e–h) treatments. i–p Isolated microspores of the responsive DH28 line after LT (i–l) and glutathione (LT + GSH; m–p) treatments. a, e, i, m Microspore suspension on the isolation day (0d). b, f, j, n Multicellular structures after 7 days (7d) of in vitro culture. c, g, k, o Multicellular structures and ELSs after 14 days (14d) of in vitro culture. d, h, l, p ELSs after 21 days (21d) of in vitro culture.
