Increasing Pine Survival and Early Growth by Planting “morphologically Improved” Seedlings
“Morphologically improved” seedlings (large-diameter seedlings grown at low nursery spacings) have a higher probability of survival (about 5% better) than regular seedlings since they have larger root systems, a higher root-weight ratio (root dry weight/seedling dry weight), and have a greater root growth potential. In addition, these seedlings will grow faster during the first several years af...
متن کاملA Three-year Study of Immersing Stored Loblolly Pine Seedlings in Water before Planting
Survival of loblollypine seedlings stored in unheated buildings from four to nine weeks improved five to eight percentage points when they were immersed in water for an hour before planting. Soaking for a day gave essentially the same results, but soaking for one or two weeks reduced survival drastically. Brief immersion of s~edling packages every two weeks during storage impro~ed survival four...
متن کاملEffect of planting depth on growth of open-rooted Pinus elliottii and Pinus taeda seedlings in the United States
Three studies in the Coastal Plain of Georgia were remeasured 7 or 8 years after planting to determine the effects of planting depth on field performance of open-rooted seedlings [root-collar diameter (RCD) ≥ 5 mm]. Average planting depth (i.e. shoot height before planting minus shoot height above ground after planting) for machine planted P. elliottii was 14 cm while hand-planted P. taeda seed...
متن کاملExtending the Planting Period of Dormant and Growing Norway Spruce Container Seedlings to Early Summer
In order to make mechanized planting economically viable, the present spring planting period for Norway spruce (Picea abies (L.) Karst.) seedlings in Scandinavia needs to be extended. To evaluate the possibilities to extend the planting period, six field experiments were established in four years during which frozen-stored, dormant seedlings and actively growing seedlings targeted for spring pl...
متن کاملAir Lateral Root Pruning Affects Longleaf Pine Seedling Root System Morphology
Longleaf pine (Pinus palustris) seedlings were cultured with air lateral root pruning (side-vented containers, VT) or without (solid-walled containers, SW). Seedling root system morphology and growth were assessed before planting and 8 and 14 months after planting. Although VT seedlings had greater root collar diameter than the SW before planting, seedling height and ground line diameter were n...
