Description
Abstract
Se han estudiado diversos parámetros (biomasa e índice de área foliar) de Rosmarinus officinalis L., una
de las especies más representativas del matorral mediterráneo, en el Campo Experimental de El Ardal (Cuenca
de Mula, Murcia) dentro del marco del Proyecto MEDALUS (Mediterranean Desertification and Land Use),
de la Comunidad Europea. Se han establecido relaciones alométricas entre la biomasa y el biovolumen que,
posteriormente, han sido utilizadas en la estimación de la biomasa media del matorral. Se ha calculado el índice foliar a partir de las relaciones peso/área foliar y peso foliar/peso total. Los resultados (836.2 g.m-2 de biomasa) muestran valores alejados del rango general aportado para otros matorrales semiáridos, hecho que
podría estar parcialmente explicado por la existencia de diversos mecanismos de compensación hídrica.
Several parameters (above ground biomass and Leaf Area Index) of Rosmarinus officinalis L., one of the most representative species of the Mediterranean matorral, has been studied in the El Ardal Experimental Field, under the MEDALUS (Mediterranean Desertification and Land Use) project, from the European Community. Allometric relationships between above-ground biomass and biovolume, which have been used to estimate average biomass in the matorral. Leaf Area Index has been calculated using leaf weight/leaf area and leaf weight/total weight relationships. Results show values (836.2 g.m-2 of biomass) far from the general range raported in othe semi-arid Mediterranean scrublands, what might be partially explained by the existence of hydric compensation mechanisms.
