Soluble N compounds in trees exposed to high loads of N: a comparison between the roots of Norway spruce (Picea abies) and beech (Fagus sylvatica) trees grown under field conditions ARTHUR GESSLER Albert‐Ludwigs‐Universität Freiburg, Institut für Forstbotanik und Baumphysiologie, Professur für Baumphysiologie, Am Flugha D‐ • The proportion of saleable seedlings was four percentage points higher in the bottom fraction than in the other seedlings. Abstract We studied the effect of soak-sorting Norway spruce (Picea abies (L.) H. Karst.) seeds on emer - gence, development and quality of container seedlings in .
During the growing session of , the total soluble non‐protein nitrogen (TSNN) composition and contents of mycorrhizal fine roots, xylem sap and phloem exudates of roots from a coniferous (Picea abies L.(Karst)) and a deciduous (Fagus sylvatica L.) tree species were analysed at a field site (‘Höglwald’, Germany) exposed to high loads of by: Cuttings of semi-ripe terminal shoots, 5 - 8cm long, August in a frame. Protect from frost. Forms roots in the spring. Cuttings of mature terminal shoots, 5 - 10cm long, September/October in a cold frame. Takes 12 months. Cuttings of soft to semi-ripe wood, early summer in a .

Seasonal Variation of Pigments in Needles of Norway Spruce Data concerning the relationship between origin of seed source and content of chloro- phyll in needles of Norway spruce are, as far as the author is informed, not available. Some rather contradictionary reports on. The large pine weevil (Hylobius abietis L.) is by far the most serious cause of damage to both Norway spruce and Scots pine seedlings in southern Finland, Sweden and Norway. The risk of seedling damage by the weevil in unprotected seedlings can be more than 75% after planting ( Cited by: 3.

Norway spruce (Picea abies) is a tough conifer that makes for an easy-care landscape tree in US Department of Agriculture plant hardiness zones 3 through is also planted extensively for forest restoration and windbreaks. Planting a Norway spruce is easy because it competes well with grass and weeds and requires no site preparation.
Damage to Norway spruce (Picea abies (L.) Karst.) seedlings by summer frost was monitored on 10 clear-cuttings of various ages to which slash removal and four types of site preparation had been clear-cuttings were established on two sites (5 on each) in southern Sweden from through and planted each year from the year of cutting until Cited by: Techniques for vegetative propagation of blue spruce (Picea pungens EngelrU.) stem cuttings were investigated.

Although Norway spruce has been investigated for growth rate, wood property traits, as well as impact of climate change, only a few studies have been conducted on resistance testing of Norway spruce clones infected by the conifer pathogen.
In this study, sixty-four (3-year-old) Norway spruce clones and seedlings in total from the Finnish. This study compared both options using eight half‐sibling clones of Sitka spruce which were propagated for 18 years.
The four treatments were propagation from the original plant (ortet), hedges from cuttings (ramets) of the first and second propagation cycles, and serial propagation from ramets of the most recent propagation by: 9.
GENERAL BOTANICAL CHARACTERISTICS: Norway spruce is an introduced evergreen tree. In central Europe, heights of up to feet (61 m) have been reported ; the range is usually between and feet ( m) .The bole is usually straight and symmetrical, with no tendency to fork .The bark of young trees has pale fine shreds .The bark of older trees is usually heavy with algae and.
Keywords: rooted cuttings, somatic embryogenesis, full sib crosses, controlled crosses, family forestry Repeated efforts in Sweden and elsewhere to use tested clones of Norway spruce in commercial clonal forestry have been going on for forty years, but have failed, and new efforts are commercially unsafe.
Propagate Norway spruce from seeds sown in spring. Seeds usually germinate readily and do not require pre-treatment. The dwarf cultivars may be propagated from tip cuttings of mature shoots taken in summer. Some of the cultivars typically are grafted onto seedlings of the species. In one-year-old container seedlings of Scots pine and Norway spruce the frost hardiness of the roots (the temperature where 50% of seedlings survive) is from −20 °C to −25 °C in mid-winter (Lindström,Lindström and Stattin, ), but the roots may suffer damage at higher temperatures reducing the roots’ ability to grow in the Cited by: 4.

With the present plastic-house technique it is possible to produce about 3-yr-old cuttings per ortet in years. The main limitations of clonal forestry are ageing of the mother plant, which with Norway spruce begins to take effect at the age of 5 yr, and the lack of genetic variation.
Clonal mixtures are recommended for practical : U. Gullberg. Abstract. Four-year-old seedlings of Piceaabies [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.
