چکیده
capacity and the ratio of hexose sugars to sucrose, consistent with the hypothesis that sucrose cycling is Sunflower canopies were grown in mesocosom gas a component of the biochemical signalling pathway exchange chambers at ambient and elevated CO 2 concontrolling photosynthetic acclimation to elevated centrations (360 and 700 ppm) and leaf photosynthetic [CO 2 ]. capacities measured at several depths within each canopy. Elevated [CO 2 ] had little effect on whole

Elevated CO2 response of photosynthesis depends on ozone concentration in aspen.
The effect of elevated CO(2) and O(3) on apparent quantum yield (varphi), maximum photosynthesis (P(max)), carboxylation efficiency (V(cmax)) and electron transport capacity (J(max)) at different canopy locations was studied in two aspen (Populus tremuloides) clones of contrasting O(3) tolerance. Local light climate at every leaf was characterized as fraction of above-canopy photosynthetic phot...
متن کاملBiochemical and molecular characteristics of leaf photosynthesis and relative seed yield of two contrasting rice cultivars in response to elevated [CO2]
Understanding the basis for intraspecific yield variability may be important in elucidating biological mechanisms that are associated with superior yield performance in response to projected increases in carbon dioxide concentration, [CO₂]. Using a free-air CO₂ enrichment (FACE) facility, two rice lines, S63 and W14, which differed consistently in their enhancement of seed yield when grown at e...
متن کاملPhotosynthetic acclimation to elevated CO2 in relation to Rubisco gene expression in three C3 species.
Wheat (Triticum aestivum L. var. DL 1266-5), sunflower (Helianthus annuus L. var. MSFH 17) and mungbean [Vigna radiata (L.) Wilczek var. P 9072] were grown in field under atmospheric (360 +/- 10 cm3 m(-3), AC) and elevated (650 +/- 50 cm3 m(-3), EC) CO2 concentrations in open top chambers for entire period of growth and development. Photosynthetic acclimation to elevated CO2 was examined by com...
متن کاملNutrient supply has greater influence than sink strength on photosynthetic adaptation to CO2 elevation in white birch seedlings.
To study the effects of source-sink ratio and nutrient supply on photosynthetic acclimation to CO(2) elevation, we subjected white birch seedlings to two levels of nutrient supply (high vs. low) and CO(2) concentrations (ambient vs. doubled [CO(2)]) for two months and then shaded the lower canopy on half of the seedlings to reduce source/sink ratio for an additional month. The CO(2) elevation s...
متن کاملPhotosynthetic adaptation and acclimation to exploit seasonal periods of direct irradiance in three temperate, deciduous-forest herbs
1. We evaluated the potential for three species of deciduous-forest herbs to exploit seasonal periods of direct irradiance. In particular, we investigated the importance of photosynthetic acclimation as a mechanism for shade-tolerant herbs to utilize direct light reaching the forest floor before canopy expansion in the spring and after canopy leaf drop in the autumn. 2. We measured the photosyn...
