Humidity affects the light response of young douglas-fir

Popis výsledku v původním jazyce

At two comparable sites with uneven-aged mixed forest stands with more than 20% Douglas-fir in the growing stock the physiological response of young trees to different light intensities was measured during the main growing season in three consecutive years and four different light categories. Climate data were obtained from the website (http://climexp.knmi.nl). Four monitoring sites were established along the elevation gradient at each site during summer and late fall to record relative humidity (RH %) and temperature (0C). Measured assimilation responses (A) and light use efficiency (Φ) at one site followed the expected pattern, while humidity combined with microsite conditions proved significant in explaining the specific response of young Douglas-fir to the different light intensity at the other site. In the changing environment, microsites with higher capacity for storage moisture and favorable microclimate should generally be preferred over exposed and dry sites for higher survival and optimal future development of the species.
