Improvement of cultivation technology for pear seedlings on dwarf rootstocks

The development of intensive fruit growing in Uzbekistan is aimed at using plants with less developed habitus of aerial parts. Such technique significantly increases the number of plants per unit area and reduces financial costs of plant care and harvesting. To improve the cultivation technology for pear seedlings and to increase yields, it is necessary to carry out a research on new vegetatively propagated rootstocks of quince, which are widely used in other countries. The research was conducted at Tashkent State Agrarian University in 2016-2018. The article presents the data on the impact of technological characteristics of individual elements of grafting of quince rootstocks by budding. The following vegetatively propagated rootstocks were used for the research: “A”, “S-А”, “R₃”, “R₄”, “R₅”, “Alushtinskaya”, “ВА-29”, “Hersonskaya” and “U”. It was established that a spine left after budding with a varietal bud had an impact on the preservation of grafted trees during the autumn and winter. During these periods the best preservation of grafted trees was recorded on almost all dwarf vegetatively propagated quince rootstocks, if spines were removed in early spring. In that case the preservation of budded buds was 86-92%, at the same time plants with spines showed 75-81% preservation.
