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. [ABSTRACT FROM AUTHOR]

The experiment was conducted during 2016–2017 on Vitis vinifera cultivars (cv.) 'Superior Seedless', 'Razakı', 'Crimson Seedless', 'Sultana', 'Royal', and American rootstocks (41B, 1103P, 1616C, Ramsey, 5BB) at Department of Horticulture, Agriculture Faculty, Ege University, Turkey. This study was designed to investigate the effects of HWT on the quality of hard wood cuttings following the treatment. The hard wood cuttings that were hot water treated at 50 °C for 30 min which is the most common protocol against Agrobacterium vitis used worldwide. After HWT, cuttings (ungrafted) were planted in black polythene bags for rooting in greenhouse conditions. In this experiment, the effects of HWT on cuttings and root distribution (0–4 scala), root number, root length (cm), shoot length (cm), sprouting rate (%), rooting rate (%), fresh and dry root weight (g) were investigated. HWT was found to have variable effects on different characteristics of cultivar and rootstock cuttings. 41B saplings were negative affected from HWT for root distribution (0–4 scala), root number, shoot length (cm), sprouting rate (%), fresh and dry root weight (g). The HWT for 41B rootstock cuttings should be done carefully. 'Superior Seedless', 'Razakı' and 'Royal' were affected positively by HWT compared to non-HWT group cuttings for some criterians.
