Abstract

Ash (Fraxinus excelsior L.) is a forest species with seeds consisting of hard woody skin and high dormancy that complicate the germination. This study was designed to facilitate the growth of ash seed using the in vitro culture of the embryo. Seeds from four regions of Kelardasht, Alandan-Kiyasar (in the Mazandaran province), Aliabad and Galikesh (in the Golestan province) were collected and sterilized using a sterilized scalpel to split tip of an embryo without any damage. Prior to being transferred to the culture medium, the embryo was washed by 70% of alcohol per minute as well as with sterile water under laminar hood. It was then placed in Monier, WPM and MS mediums in three replicates (with five ash seed per each petri dish). All indices studies here in the four geographical regions for the MS medium were significantly higher than the other two media, with the lowest amount observed in Monier culture media. In all four regions, all indices in Alandan and Galikesh were significantly higher than the other two regions, with the lowest amount observed in the Aliabad area. In addition, all indicators showed a significant and positive correlation with each other. Regressions between the length and weight index of vigor with other variables resulted in high R2 values that showed that changes in independent variables are influenced by dependent variables in a close fit. Therefore, it can be concluded that MS medium is more suitable for the in vitro propagation of the embryo plant of the ash.
