Apple trees which grafted on M.M. 106 stocks were planted at the beginning of spring 2014 in pots at the Research Institute of Horticulture in Skierniewice, Poland. 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...

The objective of the present study was to establish a possible connection between disease resistance and the carbohydrate content of plant tissues by examining sour cherry genotypes with different tolerance levels in homeostasis. 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...

Ethylene is involved in the senescence of carnation flowers. 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...

All the currently available interspecific scented cyclamen were bred by crossing Cyclamen persicum with only a wild species, C.purpurascens. 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...
Flowering and nutritional status of Gladiolus hybridus L. 'Black Velvet' following gibberellin treatmentOriginal Paper

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...
Influence of summer management practices and date of harvesting on organic acids concentration and sugar concentration in grapes of Vitis vinifera L., cv. RieslingOriginal Paper

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...
