A study of the effects of E. alphitoides on Quercus robur found it decreased stomatal conductance by 15–30%, did not affect the leaf mass to area ratio, decreased the nitrogen content of the leaf and increased dark respiration.
Un estudo dos efectos do E. alphitoides en Quercus robur amosou que a condutancia estomática se reducía un 15–30%, non afectando a masa da folla á taxa da área, reducíndose o contido de azote na folla e incrementando a respiración escura.
