Quercus suber, font primària de la undústria del suro, es posa en producció cada 9-10 anys. L’ objectiu principal d’aquest treball és investigar la influència de la lleva o pela del suro sobre l’ activitat estomàtica i les relations hídriques de la surera. Amb aquest propòsit s’han mesurat els canvis diurns de transpiración, la conductància estomàtica i el potencial hídric, en fase prévia i posterior a la pela,...
