(A) Gas exchange of Yucca gloriosa genotypes measured every 2 h over a 24-h period beginning at 1 h after lights on (0800 h). White and grey backgrounds specify daytime and night-time measurements, respectively. Mean and standard deviation are shown for days 1 (well-watered), 7 (drought stress) and 9 (re-watered). Four samples were omitted due to potentially inaccurate LiCOR measurements (genotypes 51, 55, 61 and 70).
