Adaptation experience of some ornamental and fruit-berry plantlets to ex vitro conditions in the training and science center “Botanical garden” of Saratov State University n. a. N. G. Chernyshevsky

Abstract

One of the quickways of vegetative plant reproduction is micropropagation. Receiving high results usingthis method is significantly limited by one of the most important stages – adaptation of plantlets to growing under ex vitroconditions, which completes the whole process of reproduction in vitro. To date, there are no universal technologies foradaptation plantlets to non-sterile conditions, which would suit all crops, determine the optimal humidity conditions, substrate, temperature and lighting. The article presents preliminary results of the study of the plantlets adaptive potential fora number of ornamental and fruit-berry crops in non-sterile conditions. The objects of the study were: Cotinus coggygria'Royal Purple'; Syringa vulgaris 'M-me Casimir Perier', 'А. Gromov', 'Sensation'; Pentaphylloides fruticosa L.; Weigelahybrida 'Eva Rathke', 'Candida'; Sorbus aucuparia 'Granatnaya'; Ribes nigrum 'Black Pearl', ' Bagheera', 'Elvesta', 'LittlePrince', 'Wonderful moment', 'Charovnica', 'Zusha', 'Tamerlan', 'Dachnica', 'Dessertnay Olkhina', 'Zagadka'; Lonicera edulis 'Gzhelka', 'Kamchadalka', 'Lazurnay', Moscowskay''.
