Chilling injury was assessed every 12 h, using the following
scale: (1) no damage; (2) several dark spots, (3) black less than 30%
of total leaf area; (4) black 30–50% of leaf area, and (5) more than
50% of leaf area black. Three packages of herbswere randomly sampled
each time. Young leaves and mature leaves from the same basil shoots were assessed
for CI and other parameters.
