Morphological and temperature changes under drought stress treatment over time.

(a) Water supply was stopped from the 31st day after transplantation, and the amount of water loss was measured on days 0, 2, 4, and 6. WW denotes well-watered, DC denotes drought condition. Mean and standard deviation of three repetitions. Different letters indicate significant differences (Tukey–Kramer test, P < 0.05). (b) Morphological photographs and thermal images of plants under well-watered (WW) and drought stress (DC) conditions over time from 31 d after transplantation. The number of repetitions was three pots per treatment; representative images are shown.
