Adaptation of regenerants of Vaccinium corymbosum L. and Vaccinium vitis-idaea L. to ex vitro conditions

Abstract

The benchmark analysis of the structured-functional particularities of regeneration has introduced varieties of Vaccinium corymbosum L. and Vaccinium vitis-idaea L. under in vitro and ex vitro conditions. The anatomical structures of the leaves of introduced varieties of V. corymbosum and V. vitis-idaea, cultivated in aseptical culture, greenhouse and open ground were studied. First, it is shown that the condition of cultivation superimposes the imprint on the structure and function of regeneration; secondly, the structured-functional organization regeneration (a mobile system) can be reformed in accordance with the changed condition surrounding ambiences. The differences in construction and functions of the sheet plants growing in an aseptic culture, in hothouses or open ground conditions, are indicative of the plastic sheet, which is an organ capable of reconstructing its structure and function adequately to the condition of cultivation that is theoretically, a guarantor to successful adaption of the plants when carrying them from in vitro (the cultural container) to ex vitro (the greenhouse and open ground) conditions.
