Leaf morphology and dissection index after single-leaf warming treatment. (A) Effects of single-leaf warming treatment (SLWT). LN3 was warmed at 30°C or cooled at 20°C using a plate-type temperature control system for 30 days in chamber maintained at 20°C. Upper: leaves from plants grown at 20°C with SLWT (20°C; mock-treated control); Lower: leaves from plants grown at 20°C with SLWT (30°C). The oldest leaf is shown on the left and the youngest on the right. Bar = 2 cm. (B) Dissection index (DI) of leaves. Error bars represent the standard error (SE); ** = p < 0.01 based on Welch's t-tests (n = 4; 2 plants were treated per single experiment.).
