Evaluation of pre-treatment effect of Moringa peregrina) Forssk( Fiori seed to improve germination and increase seedling establishment rate for its preservation and development in arid regions (Bashaghard-Hormozgan)

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.
