Pearson’s correlation matrix between plant yield parameters in the control (100% ASW) (a) and in the stress treatment (50% ASW) (b). FN = fruit number; FD = fruit diameter; FL = fruit length; FW = fruit fresh weight. Pearson’s correlation matrix between physiological and anatomical parameters in the control (c) and in the stress treatment (d). A = photosynthesis; gs_m = stomatal conductance in the morning (08:00–10:00); LWP_pd = leaf water potential at pre-dawn (03:00–05:00); LT = leaf thickness; gmin = minimum epidermal conductance. Blank squares mean that correlation was not significant by the t test (p > 0.05).
