The Vase Life of the Leaves of Selected Perennial Species after the Application of Growth Regulators

The aim of the study was to assess post-harvest life leaves Hemerocallis × hybrida ‘Agata’, Limonium latifolium, and Heuchera ‘Chocolate Ruffles’ after application growth regulators from group gibberellins (GAs) cytokinins (CKs), ionic liquids (2-hydroxyethyl)dimethylethylammonium gibberellinate [Chol][Gib] acetylcholine [Gib][Ach]), as well quaternary ammonium salts with anion (1-ethyl quinine [Q-C2][Gib]) 1-dodecyl [Q-C12][Gib]). were conditioned for 4 h in aqueous solutions benzyladenine (BA), meta-methoxytopolin (MemT) its riboside (MemTR), gibberellic acid (GA3), [Q-C2][Gib], [Gib][Ach], [Chol][Gib], [Q-C12][Gib] at concentrations 50 100 mg·dm?3. Conditioning ‘Agata’ MemT both concentrations, [Q-C2][Gib] (100 mg·dm?3) [Gib][Ach] (50 mg·dm?3), extended vase by 7–9 days. resulted longest latifolium.
