Abstract
Holm oak (Quercus ilex ssp. ballota [Desf.] Samp.) is an evergreen tree widely distributed in the western Mediterranean Basin. Holm oak has a poor natural regeneration, because of this it has been widely used in forest restoration programs in the Iberian Peninsula, especially in the last 10 years. However, these programs have enjoyed only limited success due to Holm oak is very vulnerable to stress conditions, especially during their first stages of life. Poor seedlings quality used in reforestation can have morphological and physiological characteristics that would impede a proper field performance. Manipulation of nutrient availability is one of the most powerful tools modifying plant characteristics. However, it still remains uncertain its effect on seedling quality and field performance of Mediterranean Holm oak. This Thesis analyzes the effect of autumn fertilization on Holm oak seedling quality parameters and field performance.
