Table 3.

Chlorophyll content determined in vivo, in lettuce leaves treated with water (CONTROL) and glutamic acid and grown under two water regimes (well-watered: NO STRESS and water stress and re-watering: STRESS)

Stress	Treatment	Chlorophyll (r.u.)
Stress	Treatment	3/07	12/07
No stress	CONTROL	7.23 ± 0.63	8.38 ± 0.79
No stress	GLUTAMIC ACID	8.70 ± 3.13	8.00 ± 0.86
Stress	CONTROL	6.26 ± 0.77	8.79 ± 0.66
Stress	GLUTAMIC ACID	6.60 ± 0.93	8.27 ± 0.68

Measures were taken during the water stress (3/07) and at the end of the cycle after the re-watering (12/07). Values are means ± SE (n = 15). Data were subjected to two-way ANOVA. Different letters, where present, represent significant differences (P < 0.05)
