Propagation and cultivation of large-fruited blackberry 'Karaka Black' and 'Black Butte' in various conditions

The method of propagation of these varieties of blackberries Karaka Black and Black Butte by green cuttings using peat and coconut substrate and growth regulators kornevin and Biofish was studied. The greatest rooting was noted when using the preparation kornevin on a coconut substrate, but according to the set of parameters of the root system (root length, number of roots and volume of the root system), it is recommended to use the complex "kornevin-Biofish". The dependence of all the parameters of the root system on the type of substrate, as well as the interaction of the substrate with varietal characteristics and the stimulator of rhizogenesis, has been reliably proved. When growing, a varietal reaction was revealed in the length of the roots and the volume of the root system to the type of container. It is recommended to use Airpot containers for growing seedlings as they provide the largest volume of the root system with the optimal root length.
