Correlogram of 9 physiologic and morphologic traits evaluated in the Perina cultivar during stress treatment atthe reproductive stage. Each trait of DS plants is normalized to that of CTRL and then correlated according to time course (t0, t1, t2). The filling of the cake corresponds to the value of the correlation coefficient (full cake means unit correlation, in absolute value) while the color indicates the sign (blue/red means positive/negative correlation coefficient).
