Abstract. Abstract. The scientific article presents experimental material devoted to the study of the influence of rootstocks of different growth strength and peach placement patterns on the habit of development and productivity of trees in the garden. Lola peach trees grown on clonal vegetatively propagated rootstocks PMG-667, VCA-1 and VVA-1, in comparison with those grafted on seed Ak-shaftali, form a less developed crown with a height limitation of 1.5, volume 2.0 times. Growing Lola peach on a low-growing vegetatively propagated rootstock VVA-1 in comparison with the use of high-growing Ak-shaftali in terms of the efficiency of the assimilation apparatus for the production of crops per unit area of diameter and crown volume has a 39% or 2.5-fold advantage. Absolutely high productivity of the Lola variety peach, both from a single tree and from a unit area of the orchard, in comparison with the use of low-growing vegetatively propagated ones, is ensured with a tree planting scheme of 6.0x4.0 meters. This indicates that this rootstock and planting pattern is not suitable for establishing intensive type orchards. The maximum productivity of peach on a low-growing vegetatively propagated rootstock VVA-1 (308.6 centners/ha) is provided with a planting scheme of 6.0x3.0 meters.
