| Popis: | ABSTRACT: International breeding programs launched new genetic material of apple rootstocks that in addition to precocity and great yield are resistant to major diseases and soil pests encountered in the largest apple producing regions in Brazil. Given this, there is a necessity for vegetative propagation of these materials for study and possible replacement of existing rootstocks. The objective was to adapt a micropropagation protocol for new apple rootstock ‘G. 814’. In the multiplication phase were evaluated BAP concentrations: 0; 0.5; 1; 2 and 4mg L-1 and in the rooting phase were evaluated IBA concentrations: 0; 0.25; 0.50; 1; 1.5 and 2.5mg L-1. These new results demonstrated that this new rootstock selection can be propagated with this tissue culture adapted protocol. For the successful in vitro propagation of apple rootstock ‘G. 814’ it is indicated the use of 1mg L-1 BAP at multiplication phase and 1.5mg L-1 IBA at rooting phase. |
