Moringa peregrina) Forssk( Fiori Is one of the valuable forest species of tropical regions which has been endangered for many years due to its special vegetative characteristics as well as improper seed harvesting and regeneration. Investigation of the effect of some pre-treatments on seed germination seems to be necessary to increase germination rate and its growth and development. This study was down with factoriel by random total project and three repite in Bashagerd Hormozgan with this goal: investigating of priming affective on seed germination characteristic. Experiment threatment are giberlic acid (0,200,400,600 ppm) and kno3 (0,1,2,3%) for 24 houres. Data varianse Analysis results show that giberlicacid has affect on germination percentage index, weight index, germination daily mean, germination value in level 5% and it hasn’t affect on germination speade, hight index and aliving percentage. In addition to both giberlic acid and kNo3 has affect on germination mean max and germination time mean in 5% level. Finaly we found that giberlic acid with 200 ppm and KNo3 concentration had the most affect on seed germination Moringa prigrina and cause to increase more than twoice growth.

With attention to the native landscape design value and the using of grasses which play a crucial role in the urban landscape, we carried out two experiments in germinator condition. This investigation was conducted to explore effects of hydro and osmopriming on germination and seedling growth of Lolium rigidum. The first experiment was carried out as completely randomized design with 4 treatments and replications. The treatments include: dry seed (control) and seed soaking in distilled water in three times 12, 24 and 48 hours, respectively. The second factorial experiment was carried out as completely randomized design with four replications. First factors included three levels of priming (seeds treated with distilled water, seeds treated with KNo3 0.2% and NaCl 45 dS/m), the second factor included three levels of time (12, 24 and 48 hours). In this research some seed germination indices such as germination percentage, germination speed, length of root and shoot, fresh and dry weight of root and shoot, mean germination time and vigor index were measured. The results of the first experiment showed that the effect of seed priming with distilled water was significant (P<0.01) than control at all times on most traits. The results of the second experiment showed that osmopriming especially KNo3 for 12 hours improved the rate and percentage of germination and growth of the seedling. Totally, osmopriming had more significant effect than control and hydropriming.
