We have analyzed the effect of different fertilizer types and doses on the morphology and peformance of five semiarid shrubs commonly used in afforestation programmes. Species selected had contrasted morpho-functional traits: Pistacia lentiscus, Quercus coccifera, Rhamnus lycioides, Rhamnus alaternus, Tetraclinis articulata. We found a relationship between application regime and root growth potential (RGP). Most of the variation in RGP was explained by seedling size, suggesting that other effects of nutrient application were less important. Short-term mortality reduced by nitrogen and phosphorus deficiency and nutrient hardening. No positive relationship was observed between RGP and transplant shock. Results contrast with works carried out in sub-humid areas.
