The pretreatment with different putative molecules had a significant
effect (p < 0.01) on leaf RWC in previously pretreated
plants exposed to chilling stress and this compared to control
plants. Leaf RWC in pretreated plants was kept unaltered and relatively
stable around 85% but was with no significant differences
between treatments. In control plants, slight significant decrease
(p < 0.01) was observed in RWC leaves (Fig. 2).
