Индукцию каллуса и адвентивных побегов из листовых эксплантов проводили на модифицированной среде МС с 30 г/л глюкозы в присутствии 6-бензиламинопурина в сочетании с одним из ауксинов ИУК, ИМК, НУК или 2,4-Д. Соотношение цитокинин: ауксин в среде составляло 10:1 или 20:1. Наилучшая регенерация гейхеры гибридной (до 92% регенерирующих листовых дисков) получена на средах, содержащих 6-бензиламинопурина в концентрации 4,0 мг/л в сочетании с НУК в концентрации 0,2 мг/л или 0,4 мг/л. В этом случае число адвентивных побегов на регенерирующий диск могло доходить до 7‑9 и более. Максимальная частота прямой регенерации наблюдалась на средах, содержащих ИМК. На средах, содержащих 2,4-Д, образовывался обильный каллус.</p></abstract><trans-abstract xml:lang="en"><p>The problems of morphogenesis’ induction from isolated leaf explants of the variety Georgia Plum of Heuchera hybrid were studied for the first time. The induction of callus and of adventitious shoots from leaf explants on the modified MS medium containing 30g/l glucose was carried out in the presence of 6-BAP in combination with one of the auxins IAA, IBA, NAA or 2,4-D. The cytokinin: auxin ratio in the medium was 10:1 or 20:1. The best regeneration of Heuchera hybrid (up to 92% of regenerating leaf discs) was obtained on media containing 6-BAP at a concentration of 4.0 mg/l in combination with NAA at a concentration of 0.2 mg/l or 0.4 mg/l. In this case, the number of adventitious shoots per regenerating disc could reach 7‑9 and more. The maximum frequency of direct regeneration was observed on media containing IBA. Abundant callus formation was observed on media containing 2,4-D.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Гейхера гибридная</kwd><kwd>фитогормоны</kwd><kwd>каллусогенез</kwd><kwd>морфогенез</kwd><kwd>адвентивные побеги</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Heuchera hybrid</kwd><kwd>plant hormones</kwd><kwd>callusogenesis</kwd><kwd>morphogenesis</kwd><kwd>adventitious shoots</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Гущин А.В., Калашникова Е.А., Киракосян Р.Н.
