GRANADOS GARCIA, María E. et al. Effect of light and soil moisture on physiological variables in six Mediterranean forest species planted under a pine forest canopy. Rev. Chapingo ser. cienc. for. ambient [online]. 2019, vol.25, n.3, pp.461-476.  Epub 19-Fev-2021. ISSN 2007-4018.


Resprouter species, by regenerating rapidly, can maintain an optimal carbon balance and improve the resilience of ecosystems that have been disturbed or are at high risk of fire.


To assess the effect of light availability and soil moisture on the ecophysiological variables of six resprouter species planted under cover of Pinus halepensis Mill.

Materials and methods:

Arbutus unedo L., Rhamnus alaternus L., Quercus ilex L., Quercus faginea Lam., Fraxinus ornus L. and Acer granatense Boiss. were planted in plots with three pine densities per hectare: HD = 800 to 1 100, MD = 300 to 600 and LD = 100 to 250. The species were also grown in the nursery, trying to maintain the same solar radiation conditions. Photosynthesis (A), stomatal conductance (Gs), photosystem II maximum efficiency (Fv/Fm) and water use efficiency (IWUE) were measured.

Results and discussion:

Evergreen sclerophyll species (A. unedo, R. alaternus and Q. ilex) showed higher photosynthetic capacity, lower photoinhibition and lower IWUE than deciduous species. In HD, plants showed lower photosynthetic capacity (P < 0.01) and higher photoprotection (P < 0.001). The IWUE was similar under the three pine forest densities. In the nursery, A was high under 100 % and 50 % light conditions; Gs was higher under 20 % conditions; and IWUE was high under 100 % light.


The physiological variables of the species were conditioned by shading and changes in water demand produced by tree cover.
