It has been aimed that to see the influence of the stem cuttings in different lenghts (20,25,30,35 cm) and rooted cuttings planted in different spacings on the growth of the saplings of I-214 and 45/51 P.x euramericana, clones in the nurseries. At the end of first growing season the rooted cuttings and 35 cm long stem cuttings showed better figures in the plots of I-214 on the diameter and height. In the second year the differences and significant effects on the growth figures of stem cuttings and rooted cuttings disappeared. On the other hand the influence of spacing was recorded in the second year and determined that the best spacing is that which gives 0.80-1.00 square m area per plants. In the plots of 45/51 clones, at the end of first growing season the cuttings of 25 and 30 cm lenghts showed better results on the growth of saplings. In the second year 30 cm stem cuttings and rooted cuttings influenced positively the height and diameter growth. As far as the survival rates are concerned the plots of rooted cuttings showed better results
