Reduced ABA concentration in the remaining leaf and roots of partially defoliated tomato plants. ABA (A, B) and ABA glucosyl ester (ABA-GE) (C, D) concentration in leaves (A, C) and roots (B, D) of partially defoliated (open bars) and control (hatched bars) M82 tomato plants. Samples were collected before defoliation (0), and 4 d and 8 d after partial defoliation. Data represent means (±SE) of six biological replications. Different letters indicate significant differences between control and partially defoliated plants at each time point using Student’s t-test (P<0.05).
