Available in PDF, EPUB and Kindle. Book excerpt: First-year survival and growth of superior and commercial slash pine seedlings, grown on both high and low beds, were compared on a typical north Florida flatwoods site. Average survival of the commercial seedlings was 80 percent, and that of the superior seedlings was 60 percent. Four of the fourteen superior families survived better than did the commercial seedlings, but four others had less than 50 percent survival. most mortality occurred during a severe drought shortly after planting. The superior seedlings were 0.27 foot taller than the commercial seedlings at outplanting and 0.33 foot taller after the first year in the field. Neither survival nor growth was significantly affected by bed height. Results suggest that it may be feasible to select slash pine for both drought resistance and superior growth rate.
