Extending 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 کاملEffect of Thawing Duration and Temperature on Field Performance of Frozen-Stored Norway Spruce Container Seedlings
Increasing use of frozen storage in nurseries at northern latitudes calls for thawing methods that are safe, economical and easy to apply on a large scale. The easiest and most economical method would be to thaw seedlings in the same boxes they were stored in. However, doing this safely requires more knowledge about how long and at what temperatures seedlings should or can be kept in the boxes ...
متن کاملCytokinins in Norway Spruce Seedlings and Forest Soil Pollution
KRAIGHER H. & HANKE D.E. 1996. Cytokinins in Norway spruce seedlings and forest soil pollution. Phyton (Horn, Ausrtia) 36 (3): (57) (60). Cytokinins can correlate with pollution damage in spruce trees and also with different strains and species of their mycorrhizal symbionts. In our study, Norway spruce seedlings were grown in vitro on sterilized or nonsterile soil substrates from two different...
متن کاملPhysiological responses of Norway spruce (Picea abies) seedlings to drought stress.
Four-year-old seedlings of Picea abies [L.] Karst (Norway spruce) were grown in semi-controlled conditions with three watering regimes. The seedlings in the control group (c) were watered to prevent any dehydration effect. The two remaining groups were subjected to mild (ms) and severe water stress (ss), respectively. The following physiological variables were monitored until ss seedlings began...
متن کاملStorability and freezing tolerance of Douglas fir and Norway spruce seedlings grown in mid- Sweden
Climate change provides new challenges to Nordic forestry. Use of non-native species, such as Douglas fir, can be a means of mitigating the effects of climate change and meeting the growing demand for biomass. When Douglas fir is grown in Sweden, it is several degrees of latitude north of its normal range, which can affect timing of growth cessation, hardening of seedlings, and seedling storabi...
