    Beschreibung / Inhaltsverzeichnis: Samenvatting De invloed van ozon op de vatbaarheid van boon voorBotrytis cinerea werd onderzocht. Een dag na de blootstelling van vier bonecultivars gedurende 8 uur aan 0, 120, 180 en 260 μg ozon m−3, werden primaire en drietallige bladeren geïnoculeerd met conidiën in water of in een anorganische fosfaatoplossing (Pi). Zichtbare beschadiging door ozon nam met de concentratie toe in alle cultivars. De primaire bladeren waren gevoeliger dan de drietallige. In tegenstelling tot conidiën in water, verooraakten conidiën in de Pi-oplossing lesies op gezonde bladeren. Bij ozonbeschadiging vertoonden bladeren van alle cultivars lesies doorB. cinerea na inoculatie in water. Voor primaire bladeren was het aantal lesies significant gecorreleard met de bladbeschadiging. Na Pi-inoculatie nam bij de ozongevoelige cultivars het aantal lesies ook toe met de concentratie ozon. Echter, de ozontolerante cultivar Groffy vertoonde eerst een afname in de door Pi gestimuleerde infectie bij de laagste ozonconcentratie. De door ozon verhoogde vatbaarheid van drietallige bladeren was minder dan die van primaire bladeren. De resultaten tonen aan dat realistische concentraties van ozon boon vatbaarder maken voorB. cinerea. Deze stijging in vatbaarheid is afhankelijk van het niveau van de ozonbeschadiging die wordt beïnvloed door cultivar, soort blad en ozonconcentratie.
    Notizen: Abstract The impact of ozone in predisposingPhaseolus vulgaris toBotrytis cinerea has been investigated. One day after 8 h exposures to 0, 120, 180 and 270 μg ozone m−3, primary and trifoliate leaves of four bean cultivars were detached and inoculated with conidia suspended in water or in an inorganic phosphate (Pi) solution. Visible ozone injury increased with increasing ozone concentrations in all cultivars. Primary leaves were more sensitive than trifoliate leaves. Conidia suspended in Pi solution caused lesions on healthy leaves, whereas conidia in water did not. Ozone-injured leaves of all cultivars showed lesions byB. cinerea after inoculations in water. The number of lesions was significantly correlated with ozone injury for primary leaves. After Pi inoculations, the number of lesions on the ozone-sensitive cultivars also increased with increasing ozone concentrations. However, the ozone-tolerant cultivar Groffy showed first a decrease in the Pistimulated infection at the lowest ozone dosages. The trifoliate leaves of all cultivars were less predisposed to the fungus than the primary leaves. The results indicate that realistic concentrations of ozone enhance the predisposition of bean leaves toB. cinerea. The rate of enhancement depends on the level of ozone-induced injury which was influenced by cultivar, leaf and ozone concentrations.

    Notizen: Abstract The effects of ozone on the susceptibility of leaves ofPhaseolus vulgaris toSclerotinia sclerotiorum andBotrytis cinerea have been investigated. Seedlings of one ozone-sensitive (‘Pros’) and five relatively ozone-insensitive cultivars (‘Gamin’, ‘Precores’, ‘Groffy’, ‘Narda’, ‘Berna’) were exposed to different ozone concentrations (0, 120, 180 and 270 μg m−3) for 8 h. One day after the exposures, primary leaves were detached and immediately inoculated with spores of either pathogen suspended in water or in a 62.5 mM KH2PO4 (Pi) solution. Visible ozone injury differed between the cultivars and increased with increasing ozone concentration. On the leaves of non-exposed plants, spores of the pathogens suspended in water caused very few lesions, whereas fungal pathogenicity was stimulated by addition of Pi to the inoculum. Ozone-injured leaves of all cultivars exhibited lesions after inoculation of the leaves with the pathogens suspended in water, and the number of lesions was positively correlated with the level of ozone injury for either pathogen and cultivar. The increase in susceptibility of bean leaves in response to increasing ozone concentrations was greater forB. cinerea than forS. sclerotiorum when spores were suspended in water, but was similar when the spores were suspended in Pi. In general, the number of lesions following inoculation with spores in Pi increased with increasing ozone concentration. However, the number of lesions in the ozone-insensitive ‘Groffy’ was reduced by an exposure to 120 μg m−3 but increased with higher concentrations. This pattern of susceptibility response to the pathogens was not found in the other ozone-insensitive cultivars and, thus, did not appear to be related to the inherent ozone-insensitivity in bean.
