Intensification techniques in the cultivation of seed rootstocks of VNIISPK breeding for the production of pear seedlings

The article presents the results of research on optimizing methods intensification growing seed rootstocks based common quince VNIISPK breeding in a nursery. In course research, it has been found that highest yield with optimal economic and biological characteristics is provided by sowing germinated seeds late April. Seeds should be sown artificial beds according to scheme 0.5 cm x 20 cm, which will allow obtain high seedlings good quality increase efficiency rootstocks. With dense scheme, annual growth does not form branches. A close linear relationship also between length skeletal roots seedlings, from follows longer seedling is, its are. There decrease indicators when field nursery, additional rearing necessary studies this direction continued.
