Fig. 3.
Effect of water stress (PEG) on plant fresh weight(g) in cultivars Olimpia and
Jazzy. Plants were grown in a standard nutrient solution for 10 days. Then, 50% of
the plants were subjected to water stress by adding PEG 6000 to the nutrient
solution(controlvs.PEG-plants).Plants remained under these conditions for3days.
For all treatments, values are the mean of 4 replicates standard error. The level of
signi ficance of Tukey’s test for each cultivar is shown at the top of each bar; *
