Ensayo de producción de Quercus suber L. en vivero: criterios para la evaluación de la calidad de las plantas.

Abstract

Seedlings of Quercus suber L. were produced in the Nursery of the Instituto Superior de Agronomia in Lisbon. The experimental design used was a factorial 2x2, with two containers types and two growing media, with five randomised complete blocks. Seedling quality was evaluated by morphological and physiological characteristics and by root electrolyte leakage (R.E.L.). Physiological criteÍ"ia were not sensible enough to detect statistically significant differences between treatments. Through morphological criteria it was possible to
