Abstract
Salinity is one of the main limiting factors for seed germination and seedling growth. The use of nutrients in priming
treatment is known as an effective way to improve seed yield In this regard, a factorial experiment was conducted in the
Khuzestan University of Agricultural Sciences and Natural Resources, based on randomize complete design with three
replications. Priming treatment with nano and micro magnesium was performed at five concentrations zero, 50, 100, 200,
400 mg /litr, sepcratly. The durations of 12 and 24 hour were used for seed priming and salinity stress levels were zero, 50,
100, 150, 200, 250 mM made with sodium chloride. The results showed that increasing salinity stress declined hyssop seeds
resistance and reduced the germination characteristics of this plant. Priming with 400 mg/litr magnesium microclate
produced the highest germination percentage of 89.3%, average germination time of 5.9, seed vigor of 27.2 and root length
of 24 mm. The highest germination rate (0.461 per day) and shoot length (18 mm) were observed in control and 400 mg/litr
of nano-chelate, respectively. Results showed that nutrient seed priming with micochelate effectively alleviated salinity
stress effects and improved seed germination properties compared to nanochelate magnesium. The optimum seed priming
treatment obtained from 400 mg/litr micro chelate magnesium for 12 hours.
Keywords: Improve seed performance, Pretreatment, Nano, vigour.
