“…High susceptibility of the cultivar 'Edda' Victoria* 9 0 1 *control cultivar; **on a 1-9 point scale, where 1 means withering or withered trees, 9 -no symptoms to the Plum pox virus was recorded by Preda et al (2012) in an experiment conducted in Romania. The occurrence of sharka on 'Jubileum' plum trees was also found in earlier studies conducted in Poland (Rozpara et al 2010;Malinowski et al 2013) and also in the Netherlands (Verhoeven et al 1998), whereas Ogašanović et al (2006), based on an experiment conducted in Serbia, recognized the cultivar 'Jubileum' as tolerant to sharka. In the available literature, there is no information on the susceptibility of the cultivars 'Reeves' and ' Avalon' to the Plum pox virus.…”

'Victoria' were the control combination. On the basis of the eight-year study it was found that the most vigorously growing were trees of the cultivar 'Excalibur' . The most susceptible to frost damage and infection by Chondrostereum purpureum (silver leaf ) were trees of the cultivars 'Edda' and 'Excalibur' . In addition, the cv. 'Excalibur' was characterized by high susceptibility to the Plum pox virus (sharka). The highest cumulative fruit yield was shown by the cultivar 'Jubileum' . The worst fruiting were trees of the cultivar 'Mallard' . Fruits of the cv. 'Excalibur' had the highest weight. The smallest were fruits of the cv. 'Edda' characterized by early ripening time. The highest amounts of soluble solids were contained in fruits of the cultivar ' Avalon' . The cvs 'Edda' , 'Reeves' and ' Avalon' proved suitable for cultivation in Polish climatic conditions.

“…Plum pox virus (sharka) is a serious problem in plum production in Poland Rozpara et al 2010;Malinowski et al 2013). In our experiment, the most severe symptoms of the disease were recorded on the trees and fruits of the cultivar 'Excalibur' .…”

“…divaricata C. K. Schreid). It does not ensure the requirements of intensive orchards due to its excessive vigour (Grzyb et al, 2010;Rozpara et al, 2010;Markuszewski and Kopytowski, 2013) and incompatibility with some European cultivars (Lepsis et al, 2004). Fluctuation of dry matter concentration in trees during winter is one of the factors that characterise compatibility between rootstock and cultivar (Dekena et al, 2013) and scion winter cold resistance (Snyder and De Melo-Abreu, 2005).…”

The issue of the influence of rootstock on winter-hardiness of plum (Prunus × rossica Erem.) tree flower buds in the Baltic region is becoming important. The choice of rootstock is the main precondition for obtaining a high yielding and sustainable plum orchard. Freezing of flower buds is one of the most significant damages in winter for stone fruits. The aim of the investigation was to determine the relationship between concentration of dry matter and reducing sugars in annual shoots during winter and wintering ability of trees. The dynamics of reducing sugar concentration in one-year-old shoots during winter was investigated during two successive seasons in two locations. Orchards were planted in 2001 in Latvia and in Estonia. The well-known plum cultivar ‘Kubanskaya Kometa’ (Prunus rossica Erem.) was grafted on eight clonal rootstocks (‘St. Julien A’, ‘Brompton’, ‘Ackermann’, ‘Pixy’, GF8/1, G5/22, GF655/2, and ‘Hamyra’) and eight generative propagated rootstocks (‘St. Julien INRA 2’, ‘St. Julien d’Orleans’, ‘St. Julien Noir’, ‘Brompton’, ‘Wangenheims Zwetsche’, ‘St. Julien Wädenswill’, ‘Myrobalan’ and Prunus cerasifera var. divaricate). Shoot samples were harvested two times during winter — at the end of January and at the end of March. Dry matter concentration (mg·g−1) and the concentration of reducing sugars (mg·g−1 DM) by Fehling’s solution method was determined. Tree flowering intensity was scored using a scale from 1 to 5, where 1 = no flowers and 5 = abundant flowering. Dry matter concentration in plum shoots varied among rootstocks, years and growing location. In Pūre, Latvia, the largest differences in dry matter concentration were found for trees grafted on ‘St. Julien INRA2’ (in 2011–2012) and ‘Brompton’ cuttings (in 2012–2013) but in Polli, Estonia for trees grafted on G5/22 (in 2011–2012) and ‘Myrobalan’ (in 2012–2013). One of the most stable rootstock/graft combinations in the trial when GF655/2 was used as rootstock, where dry matter concentration was between 491 and 525 mg·g−1, and reducing sugars between 37.5–49.2 mg·g−1, and flowering intensity between 2.5 and 4.

“…has been the most broadly used rootstock in plum orchards in the region for a long period. However, this rootstock does not correspond to the demands of commercial horticulture -it produces trees of vigorous growth (Rozpara, Glowacka, 2010;Sitarek, Grzyb et al, 2007). Also, it is not suitable for hobby gardeners if gardens are located in wet soils and if there is incompatibility between rootstock and cultivar observed (Lepsis, Drudze et al 2004).…”
