Abstract
In this study, some seed characteristics of the species of pear (Pyrus elaeagnifolia Pall.), common pear (P. communis L.) and wild pear (P. amygdaliformis Vill.) and the effects of different sowing time and cold-wet stratification combination treatments on germination percentage of those species were investigated. The germination data relating with those of treatments were separately analyzed by using SPSS Statical Software and controlled by Duncan Test. The variance analysis showed that there are significant differences between the sowing times at 0.001 probability level and different cold-wet stratification combination treatments of the three species. In this connection, it was found that the highest germination percentages were obtained from direct sowing time made on 2 nd November of 2004, direct sowing time made on 2 nd January of 2005 and sowing time made on 2 nd March after two monthly cold-wet stratification treatment at 6-7 °C temperatures, respectively. The poorest germination percentages were obtained from the latest direct sowing time made on 2 nd May of 2005 and direct sowing time made on 2 nd April of 2005. Keywords: Pear, Seed, Stratification, Sowing Time.
