Tree pruning is carried out to reduce conflict with infrastructure, buildings, and any other human activity. However, heavy may result in a diminished tree crown capacity for sugar production exposure fungal infection. This risk leads decrease stability or vigour. In this work, we analysed the effect of roadside trees on photosynthetic performance process compared neighbouring unpruned trees. Four years growth was studied by terrestrial imaging. vitality (Roloff’s classification) (Visual...

The success of establishing new trees in cities and their subsequent growth depend, among others, on the proper selection tree species which can easily tolerate post-planting stress. In spring 2023, young Italian alder (Alnus cordata (Loisel.) Duby) common lime (Tilia × europaea L. ‘Pallida’) were planted a street heavy traffic Warsaw. summer leaf samples collected during growing season for chlorophyll fluorescence measurements chemical analyses. Additionally, autumn phenological phases...

Optimal nitrogen availability is necessary to keep high photosynthetic efficiency and in consequence, good physiological condition growth of plants. In order examine the effect N nutrition on apparatus performance we used chlorophyll a fluorescence (ChF) technique two differing Actinidia cultivars aimed select most reliable ChF parameters showing deficiency. The 4-years-old specimens growing an experimental plantation were treated with three doses data collected during years. results showed...

Urban greenery contributes to improve air quality through carbon dioxide sequestration and increase humidity by transpiration.These processes are dependent on diurnal physiological activity of vegetation as well its spatial distribution.In our study we aimed find out (1) how urban can change the atmospheric conditions during a day (2) if there is difference between housing estate interior with abundant wide street heavy traffic.The examination was carried suburban district Warsaw, in two...

The term “fortress landscape” is a holistic one which involves coverage and terrain adapted for defensive purposes. specificity of the historical heritage Polish cultural landscape expressed in great number such objects, some have been absorbed by its cities. A case point Warsaw Fortress. significant part fortification has survived to this day. Due spatial structure, manner use condition, Fortress constitutes valuable element Warsaw’s natural system. At same time, it should be noted that...

De-icing salts are harmful for road-side greenery. The aim of our study was to examine photosystem II performance in mature trees growing along a road heavy traffic relation shoot and soil salinity caused by de-icing salts. Leaves from each three specimens Aesculus hippocastanum, Tilia cordata, Betula pendula the same road, nine leaves part (RS) an opposite (OS) tree crown, were sampled June, July, September, 2017 2018. PSII RS OS compared using chlorophyll fluorescence (ChF) technique....

In the last years, JIP-test became to be a tool widely applied assess performance of photosynthetic apparatus plants growing under environmental stresses. The objective our work was check whether can help predict winter survival in plants. An experiment with outdoor vertical garden conducted June 2015 on south-oriented wall Lublin city, Poland. Plants were cultivated pockets made polyester felt and irrigated by automatic controlled system. After period (2015/2016) only 16 species cultivars...

Abstract Shrub species selection for road-side planting should consider their ability to cope with stress factors imposed by road trafic. In our examination we evaluated durability of 28 ground-covering woody and cultivars in environment Warsaw. A dendrological inventory beds located along Niepodległości Avenue was carried out 11 years after planting. The survival rate each planted group shrubs (a patch) determined. Electrical conductivity soil measured order determine salinity. Planting...
