“…However, in agreement with all previous studies supporting the GLH, we found that osmotically inactive starch, and not soluble sugars, was the component responsible for the major variation in NSC with elevation. The trend found of increasing NSC towards treeline thus, cannot be directly related to freezing avoidance or tolerance, although starch can be hydrolysed to provide free sugars for increased freezing resistance in adult trees (Alberdi et al, 1989). However, as frost may occur year-round at temperate treelines and the trees were sampled towards the end of the growing season (when trees should be prepared for frosts), the starch accumulation found in the current study seems to be more a consequence of the increase in carbon reserves following the stronger limitation of growth processes than the consequence of carbon gain.…”

Variation of mobile carbon reserves in trees at the alpine treeline ecotone is under environmental control

Summary In low temperature‐adapted plants, including treeline trees, light‐saturated photosynthesis is considerably less sensitive to temperature than growth. As a consequence, all plants tested so far show increased nonstructural carbohydrate (NSC) tissue concentrations when exposed to low temperatures. Reduced carbon supply is thus an unlikely cause for low temperature range limits of plants. For altitudinal treeline trees there is, however, a possibility that high NSC genotypes have been selected. Here, we explored this possibility using afforestations with single‐provenance conifers along elevational gradients in the Southern Chilean Andes and the Swiss Alps. Tree growth was measured at each of four approximately equidistant elevations at and below the treeline. Additionally, at the same elevations, needle, branch and stem sapwood tissues were collected to determine NSC concentrations. Overall, growth decreased and NSC concentrations increased with elevation. Along with previous empirical and experimental studies, the findings of this study provide no indication of NSC reduction at the treeline; NSC increased in most species (each represented by one common population) towards their upper climatic limit. The disparity between carbon acquisition and structural carbon investment at low temperature (accumulation of NSC) thus does occur even among genotypes not adapted to treeline environments.

Godley review: A touch of frost? Cold hardiness of plants in the southern hemisphere

This review contrasts the frost resistance of plants from the Southern Hemisphere with that of the Northern Hemisphere and is principally concerned with plants from New Zealand, Australia, and South America. It gives a brief overview of methods for determining frost resistance in the field and in controlled environments with intact or excised plant parts. It considers various methods of determining frost resistance and the expression of critical temperatures causing damage, and discusses the problems of using excised plant parts and freezing of tissues. This review, however, is not principally concerned with physiological aspects of frost resistance, but more with biogeographic aspects of the environment and quantification of the relationships between frost resistance and temperature related factors such as altitude and latitude. It gives examples of differences in frost resistance between the two hemispheres and attributes these to the contrast between the climates of largely continental land masses in the Northern Hemisphere and the oceanic environment of the Southern Hemisphere. Furthermore, it also shows similarities between the frost resistance of plants from the Southern Hemisphere during the growing season and the maximum frost resistance of tropical alpine species and further similarities between species on oceanic islands in both hemispheres. Comprehensive lists of species' frost resistance are included in tables and appendices.

“…In leaves and bark tissues of most plants, this increase arises concomitant with the hydrolysis of starch reserves. (Alberdi et al, 1989;Ashworth et al, 1993;Kandler and Hopf, 1980;Khalafalla and Palzkill, 1990;O'Neill, 1983), although some exceptions have been reported (Alden and Hermann, 1971;Ristic and Ashworth, 1993). However, hardiness-related changes in the carbohydrates of flower buds have not been documented for species other than peach [Prunus persica (L) Batsch] (Durner, 1989;Durner and Gianfagna, 1991;Lasheen and Chaplin, 1977;Layne and Ward, 1978).…”

The accumulation of total soluble sugars (TSS) and starch and their relationship to flower bud hardiness were studied in three Forsythia taxa: Forsythia ×intermedia `Spectabilis', Forsythia ×intermedia `Lynwood', and F. suspensa. Taxon hardiness was based on the mean temperature at which low temperature exotherms (LTEs) occurred during thermal analysis. Ethanol-extracted soluble sugars were quantified with anthrone, and starch was enzymatically digested and quantified with Trinder reagent. Qualitative changes in sugar content were determined with high-performance liquid chromatography and co-chromatography of authentic standards. Quantitative and qualitative changes in sugar content, similar for the three taxa, were observed in conjunction with fluctuations in flower bud hardiness, although neither TSS nor starch were correlated with mean LTE temperature. TSS was higher in acclimated than nonacclimated buds. However, after deacclimation began, sugars continued to increase with mean LTE temperature. Buds lacked starch except for a brief period during deacclimation. Galactose, stachyose, raffinose, and an unidentified carbohydrate were positively correlated with hardiness (P = 0.005, 0.001, 0.005, and 0.001, respectively).
