Abstract:
... The objective of this study was to separate the genotypic and phenotypic variation in biomass allocation for populations of Typha latifolia from habitats of differing successional maturity. Field studies revealed that the OPEN marsh population of T. latifolia suffered high levels of ramet mortality over winter and had rapid growth in ramet numbers during the growing season. In contrast, the WOODS ...

Abstract:
... Although petroleum fuels have been abundant during the past decade, alternative energy sources are needed for the long term. Sorghum [Sorghum bicolor (L.) Moench] stover has been demonstrated to be a potential biomass energy source. Complete above-ground crop removal, however, can result in soil degradation. Differential dry matter, nutrient, and carbohydrate partitioning by sorghum cultivars may ...

In the absence of herbivory, L. sempervirens acc ...

Abstract:
... Pima cotton (Gossypium barbadense L. cv S-6) exhibits foliar injury and yield reduction at ambient concentrations of O3. We tested the hypotheses that O3 reduces the allocation of biomass to the root system, and that this disrupted carbohydrate allocation impairs root hydraulic capacity relative to transpiring leaf area. Both hypotheses are supported, even though leaf area development is itself re ...

Abstract:
... We examined the hypothesis that elevated CO2 concentration would increase NO3(-) absorption and assimilation using intact wheat canopies (Triticum aestivum cv. Veery 10). Nitrate consumption, the sum of plant absorption and nitrogen loss, was continuously monitored for 23 d following germination under two CO2 concentrations (360 and 1000 micromole mol(-1) CO2) and two root zone NO3(-) concentratio ...

Abstract:
... The interactive influences of elevated carbon dioxide, water stress, and ontogeny on carbon assimilation and biomass production were investigated in northern red oak, a species having episodic shoot growth characteristics. Seedlings were grown from acorns through three shoot‐growth flushes (8–11 wk) in controlled‐environment chambers at 400, 530 or 700 μmol mol⁻¹ CO₂ and under well watered or wate ...

Abstract:
... Hot weather can cause reductions in crop yield. Cowpea [Vigna unguiculata (L.) Walp.] is sensitive to high night temperature during reproductive development, but genotypes with heat tolerance have been developed. Positive and potential negative effects of the heattolerance genes were evaluated in contrasting field environments. Six pairs of cowpea lines with differences in heat tolerance during re ...

Abstract:

Alfalfa (Medicago sativa L.) production under irrigated and rainfed conditions may benefit from improvements in water-use efficiency (WUE), the amount of forage and root biomass produced per unit of water transpired. If benefits from improved WUE are to be realized, correlations between important agronomic traits and key physiological traits associated with WUE must be determined. This study chara ...

Abstract:
... Relative to effects of flooding, little is known about the influence of hydrology-nutrient interactions on aboveground net primary production (NPP) in forested wetlands. We found that nutrient circulation and NPP were closely related along a complex physical, chemical, and hydrologic gradient in a bottomland hardwood forest with four distinct communities. Aboveground biomass, NPP, biomass partitio ...

This is a consequence of the potato plants low root density and the slow soil diffusion rate of phosphorus (P) in these soils. Our objective was to evaluate the effect of P rates on tuber yield, biomass production, and dist ...

Abstract:
... Even though plastid aldolase catalyses a reversible reaction, does not possess properties allowing it to contribute to 'fine' regulation, and would therefore be considered unimportant for the control of metabolism and growth, antisense transformants with a 50-70% decrease in aldolase activity showed an inhibition of photosynthesis and growth. We now show that acclimation of photosynthesis to growt ...

Abstract:
... The mechanisms that control sink capacity are poorly understood. In radish, a major sink is the "storage root", which begins to thicken early in development, mainly as a result of thickening of the hypocotyl. We investigated changes in the accumulation of dry matter, sink activity (increase in dry weight of the hypocotyl per unit of dry weight present per unit of time), carbohydrate content, level ...
