Opis:: Clonal micropropagation is an effective method for plant reproduction, applicable in both scientific and industrial domains. However, a significant number of microclones are lost during the ex vitro acclimatization process. To address this, the introduction of beneficial microorganisms into the rhizosphere of micropropagated plants could have a positive effect on the survival rates and external characteristics of acclimatized plantlets. The aim of this study was to determine the protective and growth promoting potential of Enterococcus italicus ONU547 and its effect on micropropagated plants during acclimatization. The antagonistic activity of the bacteria was determined using the agar block method. Lepidium sativum L. seeds were inoculated with bacterial suspensions at concentrations of 10⁶, 10⁷, and 10⁸ CFU/ml. Subsequently, the roots of the microclones were treated with suspensions of 10⁶ and 10⁷ CFU/ml, and biometric characteristics were measured. The results demonstrated antagonistic properties against various phytopathogenic fungi, including Aspergillus niger, Cladosporium cladosporioides, Alternaria alternata, Alternaria tenuissima, Rhizoctonia cerealis, Penicillium expansum, and Paecilomyces variotii. Inoculation of L. sativum L. seeds resulted in improved germination rates, increased root numbers, and enhanced root and shoot lengths. Similarly, the effects of the studied bacteria on Rubus fruticosus L. and Paulownia tomentosa Steud. during the acclimatization stage led to higher survival rates, increased shoot lengths, greater node numbers, and larger leaf areas. A concentration of 10⁷ CFU/ml was identified as optimal for inoculating the microclones. The findings indicate that E. italicus ONU547 holds promise for the inoculation of micropropagated plants during the acclimatization process. Further research is recommended to establish the specific interaction mechanisms between these bacteria and plants.

Opis:: Blackberry (Rubus fruticosus L.) breeding has been carried out at the Experimental Fruit - Growing Station of the Research Institute of Pomology and Floriculture in Brzezna since 1979. Approximately 40 - 50 combinations of crosses are carried out annually; these produce in the region of 3000 - 4000 seedlings in total. The basic aim of the programme is to provide frost resistant cultivars with high - quality fruits, for dessert or processing use. The aim of this experiment was to evaluate the following cultivars: ‘Gazda’, ‘Orkan’, three new thornless cultivars: ‘Gaj’, ‘Polar’, ‘Ruczaj’, and three other blackberry clones: 97472, 97524, 97563. In 2008 the largest yield was obtained from ‘Orkan’ (4.0 kg/plant) , but in 2009 and 2010, much of the yield was lost due to winter frosts. On 6 January 2009 and 20 December 2009, temperatures of about - 20 °C were recorded. In addition, from 23 to 27 January 2010 there were lows of - 22 and - 20 °C, and from 7 to 10 March 2010, the temperature was - 15 °C. The highest yield was obtained from clone 97524 (3.4 kg/plant), but it had a too sour taste. A significantly high yield was obtained from clone 97563 (2.8 kg/plant). Amongst the three new varieties, the highest yield was obtained from ‘Polar’ (1.9 kg/plant), slightly less from ‘Gaj’ (1.6 kg/plant) and then ‘Ruczaj’ (1.4 kg/plant). The lowest yield was produced by clone 97472 (0.8 kg/plant). The highest percentage of marketable fruit during 2008 - 2010 was obtained from the cultivars 'Gazda', 'Ruczaj' as well as the breeding clones 97472 and 97563; the smallest percentage came from 'Gaj' and 97524. ‘Polar’ had the largest fruits (6.8 g) and ‘Gazda’ the smallest (2.2 g). ‘Gaj’ and ‘Ruczaj’ had an average fruit weight of 5.5 g and 4.3 g, respectively. All the varieties and breeding clones, with the exception of ‘Orkan’, were characterised by good resistance of their flower buds to frost damage. The highest number of young shoots was produced by ‘Polar’. ‘Gazda’ had the highest number of root suckers.
