Abstract

Germination characters included germination percentage (GP%), germination speed (GS), germination period (GP), and germination value (GV) were investigated in seeds under 0 (control), -2.0, -4.0 and  -6.0 water stresses by polyethylene glycol-6000 (PEG) solutions of eight seed stand and two seed orchard populations of Anatolian black pine [Pinus nigra Arn. subsp. pallasiana. (Lamb.) Holmboe.]. Variation among the populations was also examined for the characters. Average of germination percentage was the highest (76.5%) in control seeds, while it was the lowest (40.1%) in seeds of -6 bars.  The control seeds germinated earlier (10 days) than that of other levels of water stresses. Germination speed was ranged from 3.6 (-4 bars) to 33.6 (control) in polled populations. The control seeds had the highest germination value (29.7) in polled populations. Statistically significant differences (0.05>p) were found for the germination characters among populations based on results of analysis of variance. Water stresses had significant (0.05>p) and negative effective on GP% (r=-0.685) and GS (r=-0.761), while it was significant and positive on GP (r=0.808).
