Extensive plum production in Serbia has led to a reduction in yield, quality and economic profitability, a transition to intensive production is necessary. The aim of the present study was to investigate the effects of different generative (Prunus cerasifera, Prunus cerasifera +Prunus spinosa) and vegetative (WaVit, WeiWa) rootstocks in a dense planting system (4 m × 2 m). The experiment was conducted on early high-quality domestic cultivar ‘Čačanska Lepotica’ characterised by high adaptive ability in different agro-climatic conditions. The orchard was established in 2012 at the Experimental Field for Fruit Growing of the Faculty of Agriculture Novi Sad at Rimski Šančevi, and the experiment was conducted from 2013 to 2017. Based on the research findings, Prunus cerasifera rootstock induced higher tree trunk cross-section area, while also enhancing the total soluble solids content in the fruit. Trees grafted on Prunus spinosa interstock with Prunus cerasifera as the rootstock exhibited the smallest vigour, cumulative yield and titratable acidity. On the other hand, vegetative rootstocks increased the fruit yield, weight and size.

塞尔维亚的大量李子生产导致产量，质量和经济利润下降，因此有必要向集约化生产过渡。本研究的目的是研究在密植系统（4 m×2 m）中不同砧木（Prunus cerasifera，Prunus cerasifera  + Prunus spinosa）和无性系（WaVit，WeiWa）的影响。该实验是针对早期高质量的国内品种'ČačanskaLepotica'进行的，该品种具有在不同农业气候条件下的高适应能力。该果园于2012年在RimskiŠančevi的农学院Novi Sad的水果种植实验场建立，该实验于2013年至2017年进行。基于研究结果，樱桃李砧木诱导较高的树干横截面积，同时也提高了果实中的总可溶性固形物含量。以樱桃李为砧木嫁接在刺李中间砧上的树木显示出最小的活力，累积产量和可滴定的酸度。另一方面，营养砧木增加了果实的产量，重量和大小。
