Annual ornamental plants, mostly, propagated by seeds. Seeds of some these plants have difficulties in germination due to ecological adaptations to environmental conditions. In order to investigation about the effect of different treatments on the germination of three ornamental plants, Salvia grandiflora, Bellis perennis and Alyssum maritimum, three separate experiments were accomplished based on Completely Randomized Design by 4 treatments and 4 replications. Treatments include GA3 by three levels (100, 500, 1000 PPM), sulfuric acid 50% in three time (5, 10, 20 minutes), stratification during three weeks in three temperatures (0-2, 3-4, 5-6 ˚C) and control. Means comparison was done via Duncan Test by SPSS software. The results showed that gibberellic acid with a concentration of 1000 ppm had the greatest effect on the percentage and speed of Alyssum maritimum seed germination. Cold treatment did not have a significant effect on germination and sulfuric acid treatment caused a significant decrease in Alyssum maritimum seed germination. Different concentrations of gibberellic acid and chilling treatments did not have a significant effect on the germination of Bellis perennis seed, and sulfuric acid caused a significant decrease in germination. Gibberellic acid at the concentration of 1000 ppm increased the germination of Salvia grandiflora. The highest amount of germination in sage was observed in the treatment of gibberellic acid at the level of 1000 ppm (76.65%) and temperature 0-2, and sulfuric acid in 20 minutes.

Parsley, which today is classified as a vegetable, has many properties and is used in food and pharmaceutical industries. The seeds of the native populations of this plant do not have a good germination percentage and many efforts are being made to improve the growth and germination of the seeds. In order to investigate the seed germination rate of native stands and the effect of hydropriming treatment in increasing the germination power of the seeds of these stands, an experiment was conducted in the form of a completely randomized design at four time levels (12, 24, 48 and 72 hours) against the control and with four replications among 24 native stands collected from different parts of the country and two populations with foreign origin imported were carried out. The results showed that the average seed germination percentage of the stands before treatment was 56.7% (the lowest rate was 20% in curled leaf Parsley stand and the highest was 78% in Jiroft 1 stand). Also, the hydropriming treatment had a significant effect at the level of 1% on the emergence of parsley seeds, and its greatest effect was in 24 hours. Also, the highest effect of treatment on Arak, Garmsar and Pich of Tehran was 21.8, 20.9 and 20%, respectively. The least effect of hydropriming was on the population of curled leaf parsley (7.4%). Totally, it was concluded that hydropriming can increase the germination percentage and quality of parsley seeds.
