The influence of quince rootstock forms on the survival and growth of pear varieties in the nursery

Abstract

Pear is an important cash crop, the quality, variety and types of which vary depending on the place of growth. It is believed that undersized rootstocks not only simplify the technology of its cultivation, but also accelerate the entry into fruiting. Currently, the selection of existing high-quality varieties compatible with low-growing rootstocks is a serious problem faced by gardeners growing this crop. The aim of the study was to identify the compatibility of local adaptive pear varieties with rootstock forms of quince and to study the biometric indicators of rootstock-graft combinations when grown in a nursery. The assessment of the impact of undersized quince rootstocks on the survival and development of local pear varieties in the nursery was carried out according to generally accepted methods from 2016 to 2022. The study of the parameters of accretion and development of the components of graft was evaluated visually. Biometric data were obtained by instrumental and computational methods from a random sample of healthy plants. The most promising variety – rootstock combinations in the nursery were identified, their biometric parameters were determined and a visual assessment of compatibility in the nursery was carried out. According to all the studied indicators, the best rootstock for pear varieties was the form of quince rootstock No. 1.
