Abstract

In order to evaluation of the effect different levels of gibberellic acid (0, 1000, 2000 and 3000 mg l-1) on seed germination of Sorbus aucoparia L. a randomized completely design experiment was carried out. In this research germination rate, germination value and germination percentage was recorded. Analysis of variance showed that effect of gibberellic acid on traits was significant (p≤0.05). Results showed that 1000 mg l-1gibberellic acid has highest germination rate (15.75 days), germination percentage (50.42%) and germination value (2.45).
