بررسی واکنش جوانه زنی و رشد گیاهچه اسپند و زنیان به تنش شوری

To investigate the effects of salinity on germination and seedling morphological characteristics African Rue (Peganum harmala L.) and Ajowan (Carum compticum L.) as medicinal plants, two separate completely randomized design with four replications. Treatments Includes five levels of salinity (0, 2, 4, 6 and 8 ds/m). The results showed that the highest germination percentage of African Rue was measured in the control and the lowest amount was observed at 8dc/m. whereas the germination percentage of Ajowan no significant differences were observed. The results of mean comparison indicated that, the salinity stress caused the significant decrease of seedling length, shoot length, root length, shoot and root dry weight. However, the Ajowan showed better defensive mechanisms than to African Rue to salinity stress. While significantly increased of root length, particularly in Ajowan under 4 and 8 ds/m than to 2 and 4 ds/m was by increasing root growth to moisture absorption.
