摘要：This study was for the first time conducted in a greenhouse in order to pioneer forest trees ( Elaeagnus rhamnoides ) and to determine the effects of different treatments on seed germination in Iran. This species has drought tolerance for plantation. For this purpose, seeds originating in Qazvin were placed in the greenhouse. Treatments included three factors including seed pretreatments (control, cold, ice water, hot water, lime juice and Gibberellin acid), soils (control, Stockosorb, sand and compost) and irrigation (control and supplement water). These treatments were accomplished in CRD experimental design s with five replicates. At the end (31st day) number and percentage of germination, number of days until germination, mean germination time, germination rate, germination energy, maximum germination, germination value were calculated. Average germination percentage of pretreatments was 3.75, 43.75, 17.5, 1.25, 15 and 37.5, respectively. Mean of germination in soil factor were 1.04, 5.21, 22.7 and 11.3, respectively. Germination in control irrigation and same attributes were 8.75, 33.75, 27.5, 3.75, 11.25 and 37.5 in supplement irrigation. Germination in all treatments and at whole levels was on average 20.1%. The highest germination percentage was observed in the sand. The highest average germination was seen in Gibberellin treatment.
