Rapid and complete germination is essential for the efficient production of Pinus brutia var. eldarica. Osmoconditioning has proved successful for the improvement of speedy germination of the most plant species. The objective of this study was to evaluate the effect of osmoconditioning on germination speed of Eldarica pine were assessed by seed treatment with different polyethylene different experiement. In experiment 1, seeds were 7, 9, and 11 days with three PEG concentration having water potential of -0.5, -1.1, and -1.8 MPa. In experiment 2 seeds were treated with PEG for 1, 4, 8, and 16 days having water potential of 0, -0.5, -1.8 and -4.1 MPa. After osmoconditioning seeds were grown in incubator in germination boxes on Whatman No. 1 filter paper. None of the PEG concentration or duration improved total germination. However, seed treatment up to 9 days significantly reduced days longer than 9 days was deleterious.
