Abstract
The aim of the present investigation was to study the peculiarities of primocane raspberry plants adaptation to non-sterile conditions in different substrates. For ex vitro adaptation of two varieties of primocane raspberry (Poranna Rosa and Heritage) the following substrates were used: a mixture of peat and perlite (5:1); ion-exchange substrate BIONA-111; a mixture of perlite and BIONA-111 (4:1). Due to special characteristics of the plant variety Poranna Rosa 2 groups of seedlings were studied. The results of the study allowed identifying patterns of plants development and adaptation at the investigated substrates that depend on the size of the original pre-rooted plantlets of the variety Poranna Rosa. It was found that all three types of investigated substrates provide high survival rate of regenerated plants of both varieties, as well as good development of seedlings during adaption to non-sterile conditions. At the same time the length of the roots and shoots significantly affect both the variety and type of substrate for adaptation. The mixture of peat with perlite is recommended as the most optimized substrate for adaptation of primocane raspberry varieties.
