Fig. 1. Effects of cultivar, water regime, and time of observation on the ethylene production rate of wheat seedlings. Means ± SD of three replications are presented. Rectangles at the top of the figure show the well-watered (the first 17 h) and the recovery (the last 17 h), and the line in between shows the desiccation (24 h) regime. Probabilities for cultivar effect and cultivar x hour interaction (in parentheses) are presented at the top of the figure for each water regime. DW = dry weight.
