    '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

Keyword(s) Chlorophyll fluorescence - Corylus avellana L. - Daphne laureola L. - Fagus sylvatica L. - Fraxinus excelsior L. - Gas exchange - Hedera helix L. - Ilex aquifolium L. - Prunus laurocerasus L. - Quantum efficiency - Rhododendron ponticum L. - Stomatal resistance - Ulmus glabra Huds. - Water use efficiency

The photosynthetic responses of eight tree and shrub species to simulated sunflecks was measured in the field. The net carbon exchange (NCE) of Corylus avellana and Ulmus glabra increased with irradiance up to the maximum irradiance of 230 μmol m-2 s-1. The NCE of Fraxinux excelsior, Hedera helix and the sun and shade forms of Rhododendron ponticum saturated at about 120 μmol m-2 s-1 whereas the NCE of Ilex aquifolium, Daphne laureola and Fagus sylvatica had effectively saturated at 27 μmol m-2 s-1.In all cases the quantum efficiency of NCE could be predicted from measurements of chlorophyll fluorescence and the maximum value for NCE from measurements of stomatal conductance. The relationships were combined into a model for predicting NCE/irradiance characteristics.
