Streszczenie Zawartość wapnia, potasu oraz aktywność lipoksygenazy jak również ekspresja genu kodującego LOX w owocach odmian jabłoni podatnych na występowanie gorzkiej plamistości podskórnej i tych, u których objawy tej choroby nie występują były zróżnicowane. Owoce pobrano i analizowano bezpośrednio po zbiorze w sezonie 2004 oraz po długim przech...

Urban informal green spaces (IGS) represent valuable reservoirs of biodiversity within urban areas and are increasingly recognized as integral components of green infrastructure. They are perceived as temporary ecosystems, and the management of their vegetation is relatively understudied. The development time of spontaneous vegetation on transforme...

The paper is a study of risk assessment posed by trees in selected urban woodlands (urban forests) of Warsaw. Two groups of trees were analysed and compared: exhibiting signs of maturity and ageing (hollow-bearing trees with open or hidden cavities and/or caries) and with no signs of decay. 373 individual trees growing near routes frequently or con...

Urban areas are characterised by polluted air which endangers the health and quality of life of city dwellers. Among the dangerous air contaminants is particulate matter (PM) and one of the main sources of PM in urban areas is road traffic. Studies have already shown that the air can be phyto-cleaned by plants, especially trees and shrubs. However,...

Resistance of blackgrass (Alopecurus myosuroides Huds.) and silky bentgrass (Apera spica-venti (L.) P. Beauv.) to ACCase inhibitors is a serious issue in winter cereals throughout Europe, especially as hormesis induced by herbicides has been observed in some populations. According to the literature, growth-stimulating herbicide rates are on the ris...

Herbicide resistance in weeds, including corn poppy (Papaver rhoeas L.), is an increasing problem compromising global crop production. The aims of this study were to evaluate the susceptibility of P. rhoeas populations in Poland to acetolactate synthase (ALS) inhibitors and elucidate their mechanisms of resistance. Between 2017 and 2020, 157 seed s...

Urban green spaces have been widely recognized for their ecosystem services (ES) provisioning, but their resources are insufficient. Informal green spaces (IGS), the neglected areas whose maintenance was abandoned, can complement existing greenery, generating minimal costs for the managers. In this transdisciplinary study, we investigate the role o...

It has already been proven that trees and shrubs, can efficiently remove particulate matter (PM) from air. However, almost nothing is known about PM accumulation by herbaceous plants (grasses and forbs) found in urban meadows. Meadows, unlike trees and shrubs, can be located close to roads, one of the main sources of PM in cites. The aim of this st...

Urban wasteland is of special interest to city planners. However, to integrate such areas into city space management with consideration of nature conservation aspects, a sound assessment of their ecological potential is necessary. The aim of this paper was to analyze whether carabid beetle assemblages of the wastelands are affected by soil paramete...

Particulate matter (PM) is a mixture of solid and liquid substances of organic and inorganic character suspended in air. Plants are used as biological filters of air. However, PM can be deposited on their edible parts, with a negative effect on people's health. The aim of this study was to document the PM accumulation on apples and plums harvested...

a popular presentation of results of a project "Inventory and valuation of selected degraded and polluted areas in Warsaw - natural and social potential of wastelands” no. POIS.02.05.00-00-0207/16 of 21.07.2017

In urban areas, particulate matter (PM) represents an increasing threat to human health. The ability of plants in parks and along roads in cities to accumulate PM has already been demonstrated, but nothing is known about the effect of wasteland vegetation on air quality, despite a significant proportion of greenery in polluted areas being wasteland...

Badania warszawskich nieużytków przeprowadzone zostały w ramach projektu UE „Inwentaryzacja i waloryzacja wybranych terenów zdegradowanych i zanieczyszczonych w Warszawie – potencjał przyrodniczy i społeczny nieużytków” realizowanego przez Miasto Stołeczne Warszawę w latach 2017-2019. Badania te zostały przeprowadzone dzięki współpracy specjalistów...

The creation of green tramways has become a common solution in many European cities in efforts to meet the increasing demands for green areas. However, maintaining high-quality vegetation requires costly maintenance. In this study, we assessed the possibility of managing green tram tracks in a manner that combines people’s attitudes with economic a...

Effects of the phosphorus content in a nutrient solution (15 or 50 mg P dm-3), growing substrate (rockwool or coconut fiber) and the plant growth stage (for roots: 71 or 113 days after transplanting DAT; for leaves: 71 or 92 DAT) on the chemical composition of roots, the phosphorus content in leaves and the expression of genes encoding proteins inv...

Six-week old sunflower seedlings, cv. Ogrodowy, were treated with 0, 15, 45 and 60 mg Pb dm-3, and then the content of lead and selected physiological and biochemical parameters were measured. Photosynthesis efficiency, water relations (intensity of transpiration, relative water content (RWC)) and gene-encoding metallothionein were measured three t...

Valdensia leaf blight on blueberry in Poland was reported in one commercial nursery plantation near Prażmów, Mazovia voivodship, where heavy defoliation was observed on cv. Bluecrop, grown in nursery pots, in August 2011. Older fruiting bushes were only slightly affected by the disease. Initial symptoms of the disease were small, oval to circular z...

Sooty blotch is a disease of apple and pear caused by a complex of fungi that blemish the fruit surface. Results of molecular studies indicated approximately 30 different fungi species associated with this disease. Apples and pears with symptoms of sooty blotch were collected in summer and early autumn 2006-2010 from trees grown in fungicide non-tr...

Sooty blotch and flyspeck (SBFS), a disease caused by a complex of fungi, results in substantial economic losses for commercial growers of scab-resistant apple (Malus × domestica Borkh.) cultivars in Poland. However, many species causing SBFS in Poland are unidentified and sources of inoculum are uncertain. In August 2009, signs of SBFS were noted...

Sooty blotch is one of the most common disease of apples in organic orchards in many countries. Results of molecular studies performed in USA indicated approxi-mately 30 different fungi species associated with this disease. Fungi species causing sooty blotch in Northern, Central and Eastern Poland were identified on the basis of morphol-ogy and nuc...

Seasonal and cultivar variations of the phenolic, thiol, and ascorbate compound contents as well as the antioxidative enzyme activity in six cultivars of highbush blueberry were investigated. Berries of the 'Earlyblue', 'Patriot', 'Bluecrop', 'Duke', 'Darrow' and 'Lateblue' cultivars were sampled in 2005 and 2006. Chlorogenic acid, (-)-epicatechins...

Robinia pseudoaccacia plants grown hydroponically were treated Pb(NO 3) 2 with 15, 45 mg Pb 2+ dm -3 . After 6, 12, 24, 72 hours of the metal treatment the plants were collected and dissected organs. The plants accumulated and transported to ground part 0.88% and 1.35% of total accumulated lead for the lower and higher dose of Pb 2+ re-spectively....

The aim of the study was to establish which of the two fungus species – Mycosphaerella graminicola or Septoria stellariae – infects chickweed (Stellaria media) in Poland. The identification of pathogen was based on ITS1-rDNA sequence ana-lysed after PCR-amplification of DNA isolated from infected plant material. Our studies include comparative anal...
