摘要:Taking into account the economic importance of Acer species and their frequent use in landscape architecture, both nationally and internationally, it is necessary to develop an in vitro biotechnology research to propagate some of the most popular and requested Acer varieties. The study presents data on the partial results of in vitro initiation for two varieties of Acer platanoides: 'Globosum' and 'Crimson King'. Du ring the initiation phase, Acer platanoides 'Globosum' showed the best initiation percentage, using the next nutrient composition: MS macroelements, MS microelements, MS vitamins, auxins/ cytokines 0,2:1 mg/l, while Acer platanoides 'Crimson King' variety r ecorded the best results on the nutrient medium with a different composition: MS macroelements, MS microelements, LF vitamins and auxins/ cytokine 0,4:1,2 mg/l.
