Effekter av superabsorbent på granplantors överlevnad och tillväxt / Effects of superabsorbent on survival and growth of spruce seedlings

Holm, Boris January 2014 (has links)
Denna studie beskriver effekterna beträffande överlevnad och tillväxt hos gran (Picea abeis L. Karst) vid tillsats av superabsorbent Luquasorb 1280R i samband med plantering under olika betingelser. Plantor i form av täckrot och barrot studerades. Tillsats av superabsorbent visade sig ha en positiv inverkan på de studerade parametrarna i jämförelse med referensmaterial utan tillsats av superabsorbent. Detta visade sig särskilt vid extremförsök under tak utan tillgång till vattentillförsel under försöksperioden, förutom vattentillsats i samband med plantering. / This study describes the effects concerning survival and growth of Norway spruce seedelings (Picea abeis L. Karst) by addition of superabsorbent Luquasorb 1280R in connection with planting under differnt conditions. Container seedlings and bare-root seedlings were studied. The addition of superabsorbent showed a positive influence regarding the studied parameters in comparision with reference material without the addition of superabsorbent. This was most obvious at the the extreme test under roof without access to additional water during the test period, except water added in connection with planting.
