The effects of some pretreatments including blue-green and green algae and minerals on the induction of me-tabolic and biochemical process of germination were studied in Dracocephalum kotschyi Boiss. seeds. The seeds were pretreated with green algae Spirulina platensis, Chlorella vulgaris and Dunaliella bardawil or D. IR-1 (Isolated from Gave-Khooni-salt marsh) and modified Johnson nutrient medium. Dunaliella species belong to salt marshs and waters, hence their medium was prepared by means of 0.6 % NaCl. Spirulina's nutrient medium (NM) included 0.1% NaCl. The activities of α-amylase, ß-amylase, dehydrogenase, content of total sugar, reducing sugars and total protein (all we-re measured after priming) increased in comarsion with control. Treatment without NaCl and the treatment with 0.1 % NaCl caused the highest amount of the parameters mentioned. In the presence of salt (often at 0.6 % NaCl), algae could not improve and increase the parameters. In contrast, in the absence of salt, the positive effects of algae increased. Ge-rmination indices and length of shoots and roots which were measured after sowing the seeds into Petri-dishes, showed some positive effects regarding the pretreatments. Spirulina cells filteration with or without NM (including 0.1% NaCl) caused the highest activities in α-amylase and ß-amylase and the highest amount of total sugar and FGP. Chlorella filt-eration led to the increment of dehydrogenase activity and also the root's lenght. Dunaliella cells filteration in NM (without salt) increased α-amylase and ß-amylase activities and the reducing sugars.
