Plants were grown in a computer-controlled
greenhouse under 24/20C day/night cycles. In
all experiments, plants received at least 12 h of
light either naturally or using 400-W high-
-pressure sodium lamps, and were irrigated
weekly with 225 mM 20N–20P-20K. Basil
shoots were harvested by cutting just below
the second fully expanded node from the growing
point after » 6 weeks of growth. Each
harvested shoot contained six to eight leaves
and weighed 4 to 6 g. Unless otherwise stated,
basil shoots with leaves were harvested at
» 1400 HR on sunny days. Harvested shoots
were placed in unsealed plastic bags at time of
harvest and rapidly transported to the laboratory
(» 22C) for packaging.
