Technology of virus-free plum dwarf rootstocks production

Abstract

The developed technology of virus-free plum dwarf rootstocks production agrees with EPPO standards. The technology application allows to produce virus-free planting material of plum dwarf rootstocks of class ‘A’ super-super-elite (SSE), super-elite (SE), elite and 1st reproduction of high quality and appropriate to standards.

In the technology there is described: a scheme of virus-free plum dwarf rootstocks production, selection and testing of initial plants, visual estimation of initial plants at symptoms of viral and virus-like diseases infection, making plants free of pathogens by in vitro methods, quickened micropropagation (in vitro culture, nutritive media, micropropagation, microshoots rooting, plats adaptation in non-sterile conditions), keeping and propagation basic plants in vitro and in a glasshouse; plant protection against reinfection.
