Abstract

     The objective of this study was to find out the restrictions of seedling production of Loblolly pine (Pinus taeda L.) in nursery (2003-2005). ‏The statistical analysis of seedlings qualitative and quantitative parameters (collar diameter, height, survival and quality degree) showed that there were significant differences between sowing dates of autumn and spring. In respect to mean collar diameter, the autumn sowing date was better than the spring sowing date but respect to mean height of Loblolly pine (Pinus taeda L.) there was not significant differences between sowing dates of autumn and spring. Also in respect to survival and quality, the spring sowing date was better than the autumn sowing date (P < 0.01). Continuous investigation of seedling for two years showed that only a few seedlings had suitable growth at the end of the second year (almost %7). According to lab tests, there are not any evidence of pests or diseases on the dead seedling, so physical and chemical soil test was performed and the results showed that high pH and lack of the micorhiza were the soil factors which had negative effects on the seedlings survival and growth.
