Two opposing hypotheses have been presented to explain reduced tree growth at the treeline, compared with growth in lower elevation or lower latitude forests: the carbon source and sink limitation hypotheses. The former states that treeline trees have an unfavorable carbon balance and cannot support

We studied seasonal dynamics of carbohydrate storage in red spruce (Picea rubens Sarg.) seedlings by measuring starch and sugar concentrations of old needles (>/= one year old), new needles (< one year old), stems, and roots in two stands in the Green Mountains of Vermont. Although the two stands

The present study focused on changes in the annual dynamics of the contents of non-structural saccharides (NSS) of Norway spruce vegetative buds related to their structural development under the effect of acidic pollution during the year 1995. Two types of material were analysed: (1) 4-year-old

The effect of low root temperature on net photosynthesis, stomatal conductance and carbohydrate concentration in potted Engelmann spruce (Picea engelmannii Parry ex Engelm.) seedlings was examined under controlled growth-chamber conditions. Root temperature had no effect on net photosynthesis
Carbohydrate reserve accumulation and depletion in Engelmann spruce (Picea engelmannii Parry): effects of cold storage and pre-storage CO(2) enrichment.

The effects of pre-storage CO(2) enrichment on growth, non-structural carbohydrates and post-storage root growth potential of Engelmann spruce (Picea engelmannii Parry) seedlings were studied. Seedlings were grown from seed for 202 days in growth chambers with ambient (340 micro l l(-1)) or CO(2)
Effect of season and soil treatments on carbohydrate concentrations in Norway spruce (Picea abies) mycorrhizae.

We studied effects of season and soil treatments (watering, acidification, liming and combinations of these treatments) on soluble carbohydrates of mycorrhizal roots of Norway spruce (Picea abies (L.) Karst.). Arabinose, arabitol, fructose, glucose, inositol, lactose, mannitol, pinite, quinate,
Non-Structural Carbohydrate Storage Strategy Explains the Spatial Distribution of Treeline Species.

Environmental factors that drive carbon storage are often used as an explanation for alpine treeline formation. However, different tree species respond differently to environmental changes, which challenges our understanding of treeline formation and shifts. Therefore, we selected Picea
Root growth in Sitka spruce and Douglas-fir transplants: dependence on the shoot and stored carbohydrates.

When dormant Sitka spruce (Picea sitchensis (Bong.) Carr.) transplants were lifted from the nursery in March and transferred to favorable growing conditions in a controlled environment chamber, new roots emerged and elongated even when the plants were bark-ringed so that the roots could not receive

Both short- and long-term effects of Mg deficiency on carbohydrate metabolism were investigated in 6-year-old clonal Norway spruce (Picea abies (L.) Karst.) trees cultivated in sand culture with an optimal supply of nutrients, except for Mg which was supplied at 0.203, 0.041 and 0.005 mM to provide

The effects of soil temperature on the shoot phenology, carbohydrate dynamics, chlorophyll fluorescence and cold hardiness of 4-year-old Norway spruce seedlings (Picea abies L. Karst.) were studied. The experiment was carried out under controlled conditions in the Joensuu dasotrons. Air conditions

Two unrelated, geographically distinct, highly embryogenic lines of Norway spruce (Picea abies (L.) Karst.) were analysed to identify metabolic traits characteristic for lines with good yields of high-quality embryos. The results were compared with corresponding characteristics of a poorly
Complex analytical approach to characterization of the influence of carbon dioxide concentration on carbohydrate composition in Norway spruce needles.

Water-soluble non-structural carbohydrates (NSC) in the needles of Norway spruce Picea abies [L.] Karst have been studied by using a combination of several separation techniques, having various detectors, with mass spectrometry. The intent was to find a suitable methodology that enables the
Competition modifies effects of enhanced ozone/carbon dioxide concentrations on carbohydrate and biomass accumulation in juvenile Norway spruce and European beech.

Elevated concentrations of carbon dioxide ([CO2]) and ozone ([O3]) affect primary metabolism of trees in opposite ways. We studied their potential interactions on carbohydrate concentrations and contents. Two hypotheses currently under debate were tested. (1) Stimulation of primary metabolism by

The question of whether lignin is covalently linked to carbohydrates in native wood, forming what is referred to as lignin carbohydrate complexes (LCC), still lacks unequivocal proofs. This is mainly due to the need of isolating lignin from woody materials prior to analysis, at conditions leading to
Short-term dynamics of nonstructural carbohydrates and hemicelluloses in young branches of temperate forest trees during bud break.

Nonstructural carbohydrates (NSC) are the most important C reserves in the tissues of deciduous and evergreen tree species. Besides NSC, cell-wall hemicelluloses as the second most abundant polysaccharides in plants have often been discussed to serve as additional mobile carbon (C) reserves during
