At the end of each CS period (in both experiments) a
random sample of 120 seeds was removed from each plastic
container and randomly placed in 4 plastic Petri dishes (30
seeds per Petri dish). For each treatment there were 4
replications of 30 seeds. The seeds were placed on sterilized
river sand moistened with distilled water in 9-cm plastic
Petri dishes. The seeds were dusted with fungicide, to avoid
fungi development prior to their arrangement in Petri
dishes which were randomly arranged on the shelves of the
growth chamber and were watered - as required - with
distilled water
