The 'ionic effect', i.e., changes in xylem hydraulic conductivity (k(xyl)) due to variation of the ionic sap composition in vessels, was studied in four Acer species growing in contrasting environments differing in water availability. Hydraulic measurements of the ionic effect were performed together with measurements on the sap electrical conductivity, leaf water potential and vessel anatomy. ...
Because biological invasions by some introduced tree species pose a major threat to biodiversity, early detection of invasion risks is important for managing existing and future plantings mitigating negative impacts invasions. Acer monspessulanum European with large Mediterranean sub-Mediterranean range. Due its high drought resistance, it considered well adapted climate change promising urban ...
Due to the importance of Acer monspessulanum in Iranian mountain forests, a study was carried out to reliably estimate its woody biomass and growing volume via allometric equations. Four transects, five trees in each were chosen randomly. The characteristics of standing trees including: diameter at root collar, height, number of stems and crown width were measured, then trees were finally cut d...
Specific functional traits such as shade tolerance or leaf habits can enhance root growth dynamics and structure of planted seedlings in the understory forests. We assessed how low moderate light levels (17 33% full sunlight, mimicking after-thinning stocking) affect four late successional trees, three deciduous (Acer monspessulanum L., Quercus pyrenaica Willd Sorbus torminalis (L.) Crantz) one...
جنس افرا با تعداد 8 گونه و تعدادزیادی واریته و زیرگونه، از مهمترین گونههای درختی هستند که در همه مناطق رویشی ایران انتشار دارند. از بین گونههای مختلف افرا در ایران، گونه .Acer monspessulanum L با 5 زیر گونه، ضمن برخورداری از تنوع تاکسونی بالا، بیشترین سطوح انتشار را به خود اختصاص داده است. از اینرو در همین رابطه و در حین مطالعه بر روی نمونههای هرباریومی مرکز تحقیقات کشاورزی و منابع طبیعی آذر...
