Over a three-year period (1997-1999) investigations were conducted on the effect of 6 date of cut to the stub on tree trunk diameter, height and branching of sour cherry maidens in the nursery.On the <i>Prunus mahaleb</i> seedling rootstock were found no significant influen ce of the date between January, 15 - March, 30 of cut to the stub on growth of sour cherry maidens cv. ´Łutówka' (tree trunk diameter and branching) and efficiency of nursery. The date of cutting in 15 April decreased trunk diameter and percent of the first quality trees.

The studies performed in 1997 - 1999 have shown that herbicides such as Azotop 50 (simazine, 6-chloro-N, N-diethyl-1,3,5-triazine-2,4-diamine) in the dose lkg ha<sup>-1</sup> or Afalon 50 WP (linuron, N'-(3,4-dichlorophenyl)N-methoxy-N-methylurea) in dose 1,5 kg ha<sup>-1</sup> or its mixture with Dual 960 EC (metolachlor, 2-chloro-N(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl) acetamide) in dose 1,5 l ha<sup>-1</sup> applied in early spring significantly decreased number of weeds in nursery of sourcherry trees cv. Lut6wka budded on <em>Prunus mahaleb</em> L rootstocks as compared with mechanical weed control. Both, Azotop 50 and Azotop 50 in mixture with Dual 960 EC eliminated weeds for the longer period than Afalon 50 WP and Afalon 50 WP with Dual 960 EC. Herbicides did not affect tree trunk diameter (at 30 cm. from the ground level), the number and total length of shoots of one-year-old sour cherry trees in comparison with mechanical control of weeds.

Prunus Avium L

At the experiment orchard of the Fruit Research and Extension Institute, Újfehértó, Hungary in spring 2000 a trial was designed included: Erdi bőtermő, Debreceni bőtermő, and Csengődi sour cherry (Prunus avium L) cultivars which were budded at 1999 on Oblacsinska sour cherry (as a dwarf inter stock), which had been budded on Prunus mahaleb seedlings at 1998 with the aim to investigate the dwarfing effects of Oblacsinska sour cherry cultivars on scion cultivars. Trees of each cultivar directly on Prunus mahaleb seedling, severd as controls. Use of Oblacsinska as an interstock reduced the rootstock trunk diameter. Trees of Debreceni bőtermő, and Cseng6di sour cherry cultivars with Oblacsinska interstock were smaller than similar trees grafted directly onto Prunus mahaleb as a rootstock. Trees of Erdi bőtermő grafted on Oblacsinska interstock which buded on Prunus mahaleb were the smallest. Growth of the trees was reduced also by using of the Oblacsinszka as interstock for other examined cultivars.

The present study was conducted at the Felin Experi- mental Farm, belonging to the University of Life Sciences in Lublin, during the period 2005–2008. The experimental material consisted of maiden trees of sour cherry 'Łutówka' budded on seedlings of mahaleb cherry (<em>Prunus mahaleb </em>L.) of unknown origin. The experiment evaluated the effect of four budding times: 15 July, 1 August, 15 August, and 1 September, on the quality of cherry trees in a nursery. The mean for the three years showed that budding time did not have a significant effect on the quality of cherry trees in the nursery. It was observed that the budding of mahaleb cherry performed on the two August dates (1st and 15th) had a more beneficial effect on the growth and branching of trees than the budding done on 15 July and 1 September. The quality of maiden cherry trees 'Łutówka' in the nursery was primarily dependent on weather conditions in a given growing season, which is evidenced by the significant differences between production cycles, high variation in the quantitative results in individual years, and the absence of significant differences in the mean for 2006–2008.

The same young cropping 'Regina' sweet cherry trees were foliar treated with prohexadione-calcium (Pro- Ca) in two consecutive years at a concentration of [ 125, 125 x 2, 250 ]-(A) and [ 250, 375, 500 ]-(B) mg ProCa l<sup>-1</sup>, respectively. The following year some trees from A-treatments were left untreated to observe carry-over effects (C). None of A-treatments influenced tree trunk, shoot extension and internode growth, whereas B-treatments reduced shoot extension and internode length, simultaneously increasing flower bud density, particularly by 500 mg ProCa l<sup>-1</sup>. There were no carry-over effects produced by C-trees, except some retardation in shoot extension. None of the treatments influenced the tree cropping level. Fruit diameter was reduced by A-treatments, but fruit shape (L/D ratio) and mass were reduced by treatments B, and such reduction was also exhibited by C-trees (residual effects).

Plum pox virus (PPV) is the causal agent of sharka, the most detrimental virus disease of stone fruit trees worldwide. PPV isolates have been assigned into seven distinct strains, of which PPV-C regroups the genetically distinct isolates detected in several European countries on cherry hosts. Here, three complete and several partial genomic sequences of PPV isolates from sour cherry trees in the Volga River basin of Russia have been determined. The comparison of complete genome sequences has shown that the nucleotide identity values with other PPV isolates reached only 77.5 to 83.5%. Phylogenetic analyses clearly assigned the RU-17sc, RU-18sc, and RU-30sc isolates from cherry to a distinct cluster, most closely related to PPV-C and, to a lesser extent, PPV-W. Based on their natural infection of sour cherry trees and genomic characterization, the PPV isolates reported here represent a new strain of PPV, for which the name PPV-CR (Cherry Russia) is proposed. The unique amino acids conserved among PPV-CR and PPV-C cherry-infecting isolates (75 in total) are mostly distributed within the central part of P1, NIa, and the N terminus of the coat protein (CP), making them potential candidates for genetic determinants of the ability to infect cherry species or of adaptation to these hosts. The variability observed within 14 PPV-CR isolates analyzed in this study (0 to 2.6% nucleotide divergence in partial CP sequences) and the identification of these isolates in different localities and cultivation conditions suggest the efficient establishment and competitiveness of the PPV-CR in the environment. A specific primer pair has been developed, allowing the specific reverse-transcription polymerase chain reaction detection of PPV-CR isolates.

Cherry Trees

In a randomized block experiment sour cherry trees were infected at 1, 2, 4, or 6 years of age with either the necrotic ring spot virus (NRSV) or the sour cherry yellows virus (SCYV) or with both. Tree growth was retarded by both viruses but the effects of SCYV were most severe. A marked retardation of the growth rate following SCYV infection persisted for two to five years depending on the age of the tree when infected. The growth rate of trees infected with both viruses was very similar to that for trees with SCYV only and indicates the predominance of this virus in these combinations. NRSV alone caused a slight reduction in growth rate but there was never an abrupt effect.Because the effects of SCYV on growth and tree form were severe, yields were very low. NRSV caused only a 10 to 30% reduction in growth but the reduction in yield varied from 36 to 56%. Hence the effects of NRS may be of more economic importance than the relatively minor reductions in growth have indicated.
