Nonstructural Carbohydrate

Tracing shifts in carbohydrate pools has become an important tool for studying the integration of plant responses to natural and anthropogenic stresses on tree species. As a result, the need for a rapid and sensitive analytical technique to measure the components in the total nonstructural carbohydrate pool in various plant tissues has increased. In this paper we report carbohydrate data for five species that were obtained using a high-performance anion-exchange chromatography method that uses an alkaline, isocratic mobile phase (160 mM NaOH) with triple-pulsed amperometric detection. This approach has been applied to the analysis of sugar alcohols, monosaccharides, disaccharides, and other oligosaccharides in ponderosa pine (Pinusponderosa Dougl. ex Laws.), black cherry (Prunusserotina Ehrh.), and other species roots, branches, stems, and needles. The results show the range of tissue concentrations found and suggest the usefulness of the anion-exchange method for the routine quantification of the total nonstructural carbohydrate pool in trees with minimal sample preparation and cleanup. Base-line resolution of the soluble carbohydrates was accomplished in less than 13 min. The chromatographic analysis of starch as glucose was complete in less than 4 min. Electrochemical detection enabled selectivity of the carbohydrates and higher sensitivity over the conventional colorimetric assays or high-performance liquid chromatography with refractive index detection. The minimum levels of quantification were 4.5 ng for myo-inositol, 4.6 ng for sorbitol, 4.5 ng for glucose and fructose, 17.1 ng for sucrose, and 29.7 ng for raffinose.

Storage Pools

AbstractNonstructural carbohydrate (NSC) remobilization remains poorly understood in trees. In particular, it remains unclear (i) which tissues (e.g., living bark or xylem) and compounds (sugars or starch) in woody plants are the main sources of remobilized carbon, (ii) to what extent these NSC pools can be depleted and (iii) whether initial NSC mass or concentration is a better predictor of regrowth potential following disturbance. To address these questions, we collected root segments from a large mature trembling aspen stand; we then allowed them to resprout (sucker) in the dark and remobilize NSC until all sprouts had died. We found that initial starch mass, not concentration, was the best predictor of subsequent sprout mass. In total, more NSC mass (~4×) was remobilized from the living inner bark than the xylem of the roots. After resprouting, root starch was generally depleted to <0.6% w/w in both tissues. In contrast, a large portion of sugars appear unavailable for remobilization: sugar concentrations were only reduced to 12% w/w in the bark and 2% in the xylem. These findings suggest that in order to test whether plant processes like resprouting are limited by storage we need to (i) measure storage in the living bark, not just the xylem, (ii) consider storage pool size—not just concentration—and (iii) carefully determine which compounds are actually components of the storage pool.
