The used treatments in the experiment were: NPK fertilization and bioproducts: Fertigo (Manure), Micosat, Humus UP, Humus Active + Aktywit PM, BioFeed Quality, BioFeed Amin, Vinassa, Florovit Natura and Florovit Eko. In the spring, these treatments were applied to apple trees alone or enriched with Pantoea sp., Pseudomonas fluorescens, Klebsiella oxytoca and Rhizobium sp. bacterial strains. Growth, yield and fruit quality parameters were evaluated. The results revealed that photosynthetic rate was greatly improved by the addition of bacteria to Fertigo (Manure), Micosat, Humus UP and Humus Active + Aktywit PM as compared to NPK. Tree trunk thickness was significantly enhanced with Vinassa, Florovit Natura and Florovit Eko enriched with bacteria. The application of bacterial strains increased the effectiveness of Fertigo (Manure), Humus UP, Humus Active + Aktywit PM, Biofeed Amin and Yeast in increasing significantly number and weight of fruits as compared to NPK.

Research on the sour cherry - Monilinia laxa interaction involved the comparison of two Hungarian cultivars ('Érdi bőtermő' and 'Csengődi') and their offsprings (8) by measuring the quantity of homeostatic carbohydrate fractions in their leaves and phloem tissues. The results demonstrated that the glucose quantity and the ratio of glucose and fructose to sucrose were correlated with the disease resistance of sour cherry cultivars and their hybrids. The glucose content was higher in susceptible genotypes and lower in tolerant genotypes. The hexose:sucrose ratios of susceptible genotypes were significantly higher than those of tolerant genotypes.

It is synthesized abundantly after full opening of the flowers and accelerates wilting of petals, which results in withering of the flowers. We investigated the possible involvement of ethylene production in the loss of display value of cut flowers of 'Mini-tiara' carnation, a new subspecies derived from Dianthus caryophyllus L. by interspecific cross with wild-type Dianthus species (wild pinks). Flowers of 'Mini-tiara' carnation have a unique morphology with pointed-shaped petals, some of which in the middle part of the flowers stand straight and build a dome throughout the display time, and lose their display value when the dome collapses by bending all petals outside (full opening of flowers). Ethylene evolution from 'Mini-tiara' carnation was not detected from flowers with upstanding petals, but occurred several days after the collapse of the dome (after full opening of the flowers), the time they already lost their display value. These findings indicated that ethylene production is not engaged in the loss of display value of 'Mini-tiara' carnation.

To develop cyclamen with a wider variety of fragrances, we clarified the diversity of volatile compounds emitted from the flowers of 17 wild cyclamen species. We found that 14 of the wild species emitted fragrant compounds. In particular, C. pseudibericum, C. cyprium, C. libanoticum, C. purpurascens, C. cilicium and C. alpinum emitted floral compounds, and C. mirabile emitted fruity compounds. We produced interspecific hybrids between two C. persicum cultivars and C. purpurascens (which emitted the greatest number of volatile compounds) and analysed the scent characteristics of the resulting hybrids. We found that the hybrids varied in scent characteristics, even when the same parents were crossed; for example, we obtained hybrids with various proportions of citronellol, nerol and geraniol and various ratios of floral-scented and fruity-scented compounds.

'Black Velvet' following gibberellin treatment Abstract: Flowering and nutritional status in Gladiolus hybridus L. 'Black Velvet' were assessed following gibberellic acid treatment (GA3). Treatment were applied to corm (12-14 diameter) by soaking for 30 min in water solutions of GA3 at 100, 350 and 600 mg/dm3 with a control consisting of soaking-in water. All GA3 treatments inhibited elongation of inflorescence shoots and stimulated spike elongation. None of the tested concentrations affected the number of developing flowers in the spike, except for the 100 mg/dm3 in the 2nd year of the study. All GA3 treatments stimulated calcium uptake, but had no effect on the uptake of other macronutrients. All the GA3 treatments increased manganese content in leavesbud did not affect copper content. GA3 at 600 mg/dm3 stimulated uptake of iron and boron at 600 mg/dm3 but inhibited both at lower concentrations. Zinc uptake was stimulated at 100 mg/dm3 but inhibited at higher concentration.

Riesling Abstract: The impact of summer canopy management was investigated in Vitis vinifera L., cv. Riesling. Sugar and organic acid concentrations were measured for the six defoliation treatments. Titratable acidity (TA) was measured twice before harvest and once at the date of harvest. The same measurements were done twice during wine ageing. The young wine was measured for concentrations of malic, tartaric and volatile acids. Treatments with appropriate defoliation, where shortened lateral shoots (up to two leaves) were retained, supported the process of wine grape ripening to the greatest extend in the cool climate of the Czech Republic, while treatments with almost no defoliation yielded the worst results. The TA decreased during fruit ripening after veraison and continued to decrease during wine maturation. The tendency of decreasing with time was shown for the malic to tartaric acid ratio as well. Concentrations of volatile acids were sufficiently low in each of the treatments.
