Effects Of Sower Type And Seedbed Density On Bareroot Seedling Morphology And Early Field Performance Of An East Texas Family Of Loblolly Pine, Hans Michael Williams, Tim Stewart

Faculty Publications

Precision sowing is commonly used at forest tree nurseries in order to improve the growing space uniformity of seedlings in the beds. Temple-Inland Forest Products Corporation recently purchased a vacuum sower and requested a study be conducted comparing their new sower with a drill sower on the morphological characteristics of loblolly pine (Pinus taeda L.) at lifting. The study was conducted in 2000 and repeated in 2001. The seed were sown using the two sower types to achieve four densities of 161 , 215, 269, and 323 seedlings/m2• Two half-sibling families were tested in 2000, and one halfsibling family was …
