Final evaluation of nine plum cultivars grafted onto two rootstocks in a trial established in 1998 at Holovousy

Abstract

Blažek J., Pištěková I., 2012. Final evaluation of nine plum cultivars grafted onto two rootstocks in a trial established in 1998 at Holovousy. Hort. Sci. (Prague), 39: 108-115.Nine plum cultivars newly introduced into production were evaluated in a replicated trial established in 1998 on two rootstocks planted in a spacing of 5 × 1.5 m. Trees were trained as spindles and evaluated regarding vigour, canopy performance, level and stability of yields, yield efficiency, fruit size, time of flowering and harvest season until 2010. Significant differences among cultivars were found but the most interesting were related to tree vigour, yield efficiency and fruit size. Dwarfing influence of Wangenheim seedling was negligible in Empress and Čačanska lepotica but mostly visible in Sanctus Hubertus. Wegierka Dabrowicka on both the rootstocks had the highest yield efficiency, exceeding 3 kg/m 3 of trunk cross-section area. Yield efficiency of trees grafted on Wangenheim was generally higher than those grafted on Myrobalan but the greatest difference was evidenced on Domestic Prune (more than 25%). Suggestions in terms of trees-spacing are definitively proposed upon results of this study.

The influence of rootstocks on the growth, yield and fruit quality of the plum cultivar Cacanska rana

“…Korišćenjem vegetativnih podloga slabije bujnosti može se povećati gustina sadnje, kao i prinos po jedinici površine, te omogućiti lakša primena pomotehničkih mera kao što su rezidba i berba. U poslednjih dvadeset godina objavljeni su brojni rezultati istraživanja uticaja vegetativnih podloga na smanjenje bujnosti i povećanje prinosa sorti šljive po jedinici površine (Botu et al, 2002;Kosina, 2004;Sitarek et al, 2004;Meland, 2010;Blažek i Pištěková, 2012;Mészáros et al, 2015). Nove vegetativne podloge u kombinaciji sa uzgojnim oblikom mogu poslužiti kao osnova za podizanje savremenih zasada šljive sa većom gustinom sklopa (Magyar i Hrotkó, 2006).…”

Qualitative and Nutritional Characteristics of Plum Cultivars Grown on Different Rootstocks

“…The suitable graft combinations improve plant growth under environmental stresses, yield, and fruit quality [7]. Thus, the relation between used rootstock and fruit quality of plums is the topic of many studies [8][9][10], although fruit quality is mostly a cultivar-associated trait. In addition, fruit quality, soluble solid content, or titratable acidity may be indirectly affected by several mechanism including budburst, time and abundance of scion flowering, and flower quality [11].…”

“…Many problems were reported in association with using this rootstock: non-uniformity, excessive vigour of the scion, grafting incompatibilities with certain cultivars, delayed precocity [17,19]. Better influence on tree vigour, graftcompatibility, leaf mineral content and yield have been determined for new dwarf or semi-dwarf rootstocks (such as St. Julien A, Pixi, Ishtara, Fereley) [8][9][10]20,21]. Therefore, the aim of this study was to determine the influence of generally used rootstock such as Ishtara, St. Julien A, Torinel, Citation and Penta on acidity, soluble solid content (SSC), total phenolic content (TPC), total flavonoid content (TFC), and antioxidant capacity of Japanese plums and one cultivar of European plum growing in the Czech Republic.…”

Yield Potential of Long Bearing Shoots of Ten Plum Cultivars (Prunus domestica L.)

“…It is very important, both for the for breeders and producers, to know the growth and development of new plum cultivars in specific local growing conditions. Usually, these research are done through analyses of the growth and yield parameters such as canopy size; trunk cross-sectional area; cumulative yield, fruit mass, and canopy density; and application of winter and summer pruning (Blažek et al, 2004;Blažek and Pištekova, 2012;Čmelik et al, 2007;Dinkova et al, 2007Dinkova et al, , 2012Dinkova et al, 2012;Dzintra et al, 2013;Nikolić and Milatović, 2010;Robinson et al, 2010). However, the issues of identifying the dominant type of bearing shoots, i.e.…”
