Morphological response and growth of cork oak (Quercus suber L.)seedlings at different shade levels
Morphological response and growth of cork oak (Quercus suber L.)seedlings at different shade levels
- Forest Ecology and Management, 222(1-3), p.296-301, 2006 .
In spite of the importance of shade tolerance in silviculture, some species such as cork oak (Quercus suber L.)have not been well characterized. This work aims to describe the response of cork oak seedlings to a light gradient in their first growing period. The seedlings were grown under different mesh filters and were watered to full field capacity of the soil. The response to different light levels was studied in terms of morphology and growth, measuring heights, diameters, photosynthetic apparatus dimensions and shoot and root biomass. There were three plant extractions in April, June and October. The greatest morphological plasticity was noticed in the size of the leaves, which changed from 1.8 cm2 under full sunlight to 5.8 cm2 in maximum shade. The cork oak seedlings endured light levels of 20
