The seeds of two medicinal plants, namely Chamomilla recutita (Babong) and Origanum majorana (Bardaqoush) were subjected to germination in different NaCl concentrations, polyamines (putrescine, spermidine, spermine) and to combination of both. The results revealed that the growth alterations induced by NaCl were alleviated by various levels of polyamines. The organic solutes of both plant seedlings exhibited somewhat variable responses to various salinity levels or polyamines treatments and in combination of both treatments. Putrescine in Ch. recutita seedlings was more effective in alleviating the stress effects of salinization than spermidine and spermine, while in O. majorana seedlings spermidine was more effective. Generally, the degree of stimulation differed according to the type, concentration of the additive used and the type of the plant tested.
