    'Staff publications' is the digital repository of Wageningen University & Research

    'Staff publications' contains references to publications authored by Wageningen University staff from 1976 onward.

    Publications authored by the staff of the Research Institutes are available from 1995 onwards.

    Full text documents are added when available. The database is updated daily and currently holds about 240,000 items, of which 72,000 in open access.

    We have a manual that explains all the features

Plant verdedigt zich vaak te goed tegen lichtstress : vrije radicalen, schadelijk maar ook nuttig

Een plant heeft te maken met voortdurend wisselende lichtniveaus die soms zodanig hoog kunnen oplopen dat ze schade veroorzaken. Er bestaat een uitgebreid stelsel van verdedigingslinies op alle niveaus: blad, cel, celorganen en moleculair niveau. Soms is de voorbereiding op mogelijke lichtschade zo goed dat het productie kost.
Op veel punten afwijkend, maar geen aparte teeltmaatregelen vereist : varens buitenbeentjes in de tuinbouw
Kierkels, T. ; Heuvelink, E. - \ 2016

Varens wijken in veel opzichten af van andere potplanten. Ze vormen geen bloemen en de voortplanting is een ingewikkelde zaak. Ook inwendig kennen ze tal van bijzonderheden. Daarom is het des te verwonderlijker dat ze op de bedrijven gewoon tussen andere groene planten kunnen worden geteeld.
Meer licht toelaten in potplanten : wie durft? Proefresultaten uitdaging aan de praktijk

Bij de teelt van schaduwminnende potplanten gaat veel licht, en dus productie, verloren. Het project Grip op Licht heeft de grenzen opgerekt. De planten blijken, onder voorwaarden, veel meer licht aan te kunnen. Daarbij hoort wel een betere manier van monitoren.
Naar de grenzen van het licht (interview met Filip van Noort)

Schaduwminnende potplanten kunnen veel meer licht verdragen dan ze in de praktijk krijgen, blijkt onderzoek van WUR Glastuinbouw. Daarmee is de teelt te versnellen en energie te besparen. Maar hoe ver kan een teler daarmee gaan?
Seasonal changes in photosynthesis and growth of Zizyphus attopensis seedlings in three contrasting microhabitats in a tropical seasonal rain forest

We hypothesized that photosynthesis and growth of tropical vegetation at its most northern distribution in Asia (Xishuangbanna, SW China) is adversely affected by seasonal drought and chilling temperatures. To test this hypothesis, we measured photosynthetic and growth characteristics of Zizyphus attopensis Pierre seedlings grown in three contrasting forest microhabitats: the understory, a small gap and a large gap. Photosynthetic capacity (light-saturated photosynthetic rate (Amax), maximum rate of carboxylation and electron transport rate) and partitioning of leaf nitrogen (N) into carboxylation and electron transport differed significantly among seasons and microhabitats. Specific leaf area (SLA) did not change seasonally, but differed significantly among microhabitats and showed a negative linear relationship with daily integrated photon flux (PPFi). In contrast, leaf N concentration per unit area (Na) changed seasonally but did not differ among microhabitats. Measurements of maximum PSII photochemical efficiency (Fv/Fm) indicated that chronic photoinhibition did not occur in seedlings in any of the microhabitats during the study. Photosynthetic capacity was greatest in the wet season and lowest in the cool season. During the cool and dry seasons, the reduction in Amax was greater in seedlings grown in the large gap than in in the understory and the small gap. Close logarithmic relationships were detected between PPFi, leaf Na and photosynthetic capacity. Stem mass ratio decreased, and root mass ratio increased, in the dry season. We conclude that seasonal acclimation in growth and photosynthesis of the seedlings was associated with changes in biochemical features (particularly Na and partitioning of total leaf N between the different photosynthetic pools) and biomass allocation, rather than with changes in leaf morphological features (such as SLA). Local irradiance is the main factor driving seasonal variations in growth and photosynthesis in the study area, where the presence of heavy fog during the cool and dry seasons limits irradiance, but supplies water to the soil surface layers.
