The breeding of the genus Lagerstroemia is a success story in more ways than one. The genetic variability of the species and the diversity of different traits provide breeders with excellent possibilities to produce new varieties. New products can be easily produced in nurseries. Their breeding and cultivability can be easily adapted to the product...

The importance of epigenetics in plant cultivation and breeding has been growing rapidly in the recent years, and this knowledge base is likely to expand further in the years ahead. The constantly changing climate means that our commercial and ornamental plants require reassessment and varieties need to be adapted to these climatic conditions. Epig...

The genus Rudbeckia has long played a very important role in ornamental plant cultivation and breeding. The ever-expanding variety range of many of its species is also suitable for use as potted ornamental plants and bedding plants, thus it can play a very important role in the management of urban green spaces. The development of urban vegetation i...

Ocimum basilicum L. is a multipurpose plant species used in the horticultural sector as a medicinal, herbaceous and ornamental plant. In our experiment, the Hungarian cultivar O. basilicum Rokokó was treated with algae (Ecklonia maxima (Osbeck) Papenf.), horsetail (Equisetum arvense L.) extracts and humic extracts. The effect of the biostimulants o...

Many cultivars of annual ornamental horticulture have great phenotypic qualities but are less tolerant to the effects of current climate change and urbanization. A good example of this in Hungarian ornamental breeding is the Rudbeckia hirta cultivar “Őszifény”. The objective of this study was to determine whether gamma mutation breeding (using 5 Gy...

Ornamental horticulture and breeding, as well as urban landscape architecture, are facing increasing challenges driven by an intensely changing climate and urbanisation. The expansion of cities should be combined with an overall growth of green spaces, where ornamental plant species and cultivars will have to withstand a diverse range of environmen...

In this study, we examined over 200-year-old Ginkgo biloba L. specimens under different environmental conditions. The overall aim was to explore which factors influence their vitality and general fitness in urban environments and thus their ability to tolerate stressful habitats. In order to determine this, we used a number of different methods, in...

Biostimulants and other plant growth promoters can provide an effective solution to the challenge of urbanisation and climate change. Viburnum opulus ‘Roseum’ is a globally popular deciduous shrub species that can be made more resistant to urban influences by using natural growth-promoting substances. In our study, we investigated the effects of gr...

Global warming has led to irregular precipitation patterns and various abiotic and biotic stresses, resulting in unforeseen consequences for wildlife. Plant species are particularly vulnerable to these global climate changes, struggling to adapt to the increasing stressors. Urban environments exacerbate these challenges, further hindering plant sur...

Plant growth-promoting bacteria (PGPB) and other living organisms can help with the challenges of modern agriculture. PGPB offer ever-expanding possibilities for science and commerce, and the scientific results have been very advanced in recent years. In our current work, we collected the scientific results of recent years and the opinions of exper...

The breeding of resistant, high-yield, decorative ornamental plant varieties may be impacted by climate change in the future. The use of radiation induces mutations in plants, thereby increasing the genetic variability of plant species. Rudbeckia hirta has long been a very popular species in urban green space management. The goal is to examine whet...

Several recent studies have shown that glyphosate and its metabolite, aminomethylphosphonic acid (AMPA), resist rapid degradation and, therefore, can accumulate in plants. Continuing our previous research, we aimed to investigate the effect of indirectly spraying glyphosate on leaves and soil on non-target plants in the case of Helianthus annuus L....

A botanikus kertek jelentős növénygyűjteményeket őriznek és gondoznak. A növényfajok megőrzése mellett oktatási, kutatási és rekreációs funkciójuk is kiemelkedő. Ezeknek a funkcióknak a sikeres megvalósítása nemcsak amiatt fontos, mert ezek a programok fontos bevételi források lehetnek, hanem azért is, mert terjesztik városi környezetben a kertépít...

Here we present an analysis of the nocturnal macro‑moth fauna in Répáshuta (Bükk National Park) based on the catches of a Jermy‑type automatic light‑trap between 2014‑2019. Over the six years, a total of 43,487 individuals of 488 species were caught by the trap. Species composition varied greatly between years, with a total of 141 species occurring...

Glyphosate is still the subject of much debate, as several studies report its effects on the environment. Sunflower (GK Milia CL) was set up as an experimental plant and treated with glyphosate concentrations of 500 ppm and 1000 ppm in two treatments. Glyphosate was found to be absorbed from the soil into the plant organism through the roots, which...

Jelen tanulmány a Lucilia sericata (Meigen) forenzikus entomológiai szempontból jelentős rovar kísérleti körülmények közti fejlődési menetét (metamorfózis) elemzi. Egy tetemrészlet (sertés mellső végtag) szabad környezetben megvalósuló lebomlásának folyamatát vizsgálva a L. sericata teljes fejlődési menetének fázisait végigkíséri. Vizsgálja a hőmér...

A mesterséges fény hatása a repülő állatokra, különösen a rovarokra, Arisztotelész óta jól ismert. Az utóbbi években a fényszennyezéssel kapcsolatosan egyre több tudományterület vizsgálja a jelenséget. Az ALAN (Éjszakai mesterséges fény) hatására vonatkozó ismereteink azonban többnyire a fényre repülő szervezetek fiziológiájára, viselkedésére, szap...
