This paper compares the responses to ozone in five woody species: Fagus sylvatica (FS), Acer pseudoplatanus (AP), Fraxinus excelsior (FE), Viburnum lantana (VL) and Ailanthus altissima (AA). The hypothesis being tested was that the strategies that plants adopt to resist oxidative pressure are species-specific. The study was carried out on field grown plants(More)
Different NAA plus kinetin or BA combinations were tested on Francia Pernod fennel seedlings for callus induction and plant regeneration. Callogenesis from hypocotyls was obtained in all auxin/cytokinin-containing media. The organogenic response was observed especially in presence of NAA plus kinetin. The highest frequency of shoot regeneration was found(More)
Potted plants of Ailanthus altissima, produced by root suckers coming from a single symptomatic mother tree, were placed in two sites in the vicinity of Florence (central Italy), with different levels of ozone pollution. These plants were kept in well watered conditions during the period May-September 1999. In the high pollution site (Settignano-SET) the(More)
Between May and September, 1996, seedlings of Pinus halepensis were placed at a site adjacent to an automated air pollution monitoring station within the urban area of Florence. Additional ‘control’ plants were placed in chambers ventilated with charcoal/Purafil-filtered air. All trees were well watered throughout the whole experimental period. During the(More)
The paper reports a case of evident and widespread leaf damage on trees in southern Tuscany (Central Italy) attributed to the input of pollutants produced in a geothermal area. The main potentially phytotoxic substances are boron and hydrogen sulphide. Trees affected are conifers as well as both evergreen and deciduous broadleaves. In the present study the(More)
This paper aims to investigate early responses to ozone in leaves of Fagus sylvatica (beech) and Populus maximowiczii x Populus berolinensis (poplar). The experimental setup consisted of four open-air (OA) plots, four charcoal-filtered (CF) open-top chambers (OTCs), and four nonfiltered (NF) OTCs. Qualitative and quantitative analyses were carried out on(More)
Cerato-platanin (CP), a protein previously isolated from the ascomycete Ceratocystis fimbriata f.sp. platani (Cfp), the causal agent of plane canker stain, has been studied with regard its phytotoxic effect in plane leaf cells by transmission electron microscopy. When infiltrated in plane leaf mesophyllum, pure cerato-platanin induced, 24 and 48 h after(More)
The secretory structures and the volatile fraction of Stachys officinalis (L.) Trevisan subsp. officinalis (Lamiaceae) from Italy were studied for the first time. Peltate and small capitate trichomes were observed on the whole plant (leaves and inflorescences). In the peltate trichomes, an unusual polyphenols content was evidenced by the histochemical(More)
