Влияние различных типов ауксинов на развитие побегов Rhododendron hybr. в культуре in vitro и адаптация растений–регенерантов в закрытом грунте

Abstract

The results of studies on the selection of an adaptive substrate for regenerants of rhododendron culture under the conditions of a greenhouse are reflected. It was found that the frequency of root regeneration is higher in the medium with the addition of 0.5 mg / l IMC + 0.5 mg / l IAA (100%). The rootedness of shoots, the length of shoots and their thickness from the type of auxin used do not depend reliably. Therefore, the use of a mixture of auxins during the rooting stage makes it possible to obtain microsatants suitable for subsequent adaptation to ex vitro conditions. When using a mixture of peat / perlite and peat / needles, the percentage of adapted plants and the size of the micro-seedlings are 68% higher than when using a peat / sand mixture for all the varieties under study.
