STUDY OF PLUM DOMESTIC TOLERANCE TO PLUM POX VIRUS (PPV) BY THE CRITERION "THE EFFICIENCY OF MICROSHOOTS REGENERATION" <i>IN VITRO</i>
The efficiency of shoots’ regeneration by explants from symptomatic and asymptomatic mother plum trees that are PPV carriers in the course of microcloning in vitro is studied. The results of microshoots’ regeneration show that explants from asymptomatic plants strike root and regenerate the microshoots significantly more efficiently than explants from symptomatic plants.
