Abstract
Due to the reduction of quality and non-saline water resources, it is important to cultivate plants with high tolerance to environmental stresses such as salinity. The medicinal plant of hyssop grows easily in any soil without the need for food. This study with aimed at the response of different methods of hyssop plant planting to different levels of salinity was conducted as factorial experiment based on a completely randomized design with 3 replications, during 2020-2021 growing season in Salinity Research Center, Yazd. The experimental factors included three levels of salinity (0.44 [control], 3 and 6 dS/m), as the first factor and two cultivation methods (seedlings and seeds) as the second factor. The results showed that the highest plant height (44 cm) in control (with 167% more salinity than 6 dS/m) and seedling method (43% more than seed method), leaf area (764.51 cm2 with different 55.5% than 6dS/m) was obtained in control method. maximum total dry weight (0.86 g/plant) in control (115% more than 6 dS/m) and seedling method (60% more than seed method), maximum carotenoids content (3.25 mg/g FW with different 62% more than 6 dS/m) were observed in control when seedling method was used, also, at control and seedling cultivation treatment maximum total chlorophyll content (26.87 mg/g FW and 106% more than 6 dS/m) and highest amount of sodium (9486.83 mg/kg DW with increasing 216% than control treatment) in 6 dS/m, and also highest amount of potassium (21090.09 mg/kg DW with different 30% than 6dS/m) in control, were observed. In general, in the seedling planting method, compared to seed planting, the plant had more tolerance and adaptation as well as growth.
