The experiment was established in the Pomological Orchard of The National Institute of Horticultural Research in Skierniewice in a system of randomized blocks. The aim of the experiment was to investigate the impact of innovative organic fertilizers: BioIlsa, BioFeed Ecomix, biostimulator Ausma and mycorrhizal inoculum Mykoflor on the fine roots growth characteristics of 'Vanda' sweet cherry trees in comparison with NPK mineral fertilization. The experiment involved five combinations, in three repetitions of three trees each, treated with tested preparations. The study assessed the influence of fertilization on the lifespan of the roots, the depth...

One-year-old 'Florida Prince' cultivar peach trees grafted on a 'Nemaguard' rootstock were planted in the early spring of 2018 at the Centre of Agricultural Research and Experiments, Minia University, located in southwest Egypt. The trees were planted 5 × 5 m in a randomised complete block design with four replicates, with ten trees in each replicate. In the late spring, two different pruning systems were applied; traditional open centre (OC) and de-branched top trees (DBT). The OC trees were headed at 80 cm above the ground. DBT is a modification of the OC, but no heading was undertaken and the new shoot growth arising from the 20 cm at the top of...

The wild grasses are of increasing interest among landscape architects. The appropriate plant selection is crucial for the subsequent survival and growth of plants in grassy gardens. The aim of the experiment was to assess the influence of seed age (1-3-year old seeds) on the germination of three Stipeae species: Eriocoma occidentalis subsp. californica, Stipa pulcherrima and Hesperostipa curtiseta. The seed weight and germination percentage showed a decline over a period of seed storage. There was 31-84% (depending on species) loss in germinability of 3-year old seeds in comparison to 1-year old seeds. After germination, plants were repotted and treated...

Short storage of in vitro cultures under slow-growth conditions is included in the commercial large-scale micropropagation process. It is dictated by the organizational scheme that provides temporary stop multiplication of shoots for some months. To avoid subculturing to fresh media every 4 weeks, which is obligatory for gooseberry, they can be kept in conditions that protect them from ageing, by slowing down their metabolism. To develop a rational schedule of gooseberry micropropagation, two experiments were used to adopt a temperature and length of time for storage. The best results were obtained with storage conditions at 2 °C for two or four months...

Plant galls of Aceria granati (Canestrini et Massalongo 1894) were observed on the leaves of Punica granatum (Lythraceae) in a private garden in Nitra in July, 2017. Aceria granati is a monophagous gall mite damaging the leaves of Punica granatum. This gall mite was present in one locality in Nitra only and was probably imported from Hungary via the plant trade. This is the first observation of an Aceria granati occurrence in Slovakia.

The article presents the results of the evaluation of eleven Scots rose cultivars in the northern part of Ukraine due to its severe winter conditions. A range of variations regarding the bloom colour, bloom size, bloom type, flowering incidence, plant size was noticed. The evaluation showed the decorative value and considerable frost resistance of the varieties 'Double White', 'Dunwich Rose', 'Frühlingsduft', 'Frühlingsgold', 'Frühlingsmorgen', 'Karl Forster', 'Mon Amie Claire', 'Red Nelly', 'Stanwell Perpetual', 'Suzanne', and 'William III'. The varieties studied can be used for decorative purposes in urban landscapes in the northern part of Ukraine.
