Slash Pine Selected from Nurserybeds: 8-Year Performance Record
After eight years in the field under fairly typical "flatwoods" plantation conditions, outstanding slash pine seedlings selected from nurserybeds showed a mean height superiority of 23 percent over average stock. Survival of the select seedlings was 35 percent versus 66 percent for the controls. Height- and diameter-class frequency distribution graphs showed that whereas a large number of modestly superior individuals were included in the select group, none of the selections was superior to the best of the controls. These findings are compared with those from other similar studies. It is suggested that some of the apparent discrepancies result from differences in sampling intensity and quality of the outplanting sites.
