Means and standard deviations were obtained from ten independent leaf samples grown under normal growth conditions. Means and standard deviations are obtained from 10 independent samples. Statistics treatment was made with Welch’s two-sample t test. ^∗∗Significantly different at P = 0.01. ^∗Significantly different at P = 0.05.
