C-Photosynthate Partitioning and Translocation in Soybeans during Reproductive Development.
Plant physiology, 2010Partitioning and translocation of (14)C-photosynthates were examined during flowering and seed maturation in soybean (Glycine max [L.]Merr.) plants to quantify allocation to sugars, amino acids, organic acids, and starch and to study transport of C and N from leaves to reproductive sinks.

Light‐mediated bioregulation of tillering and photosynthate partitioning in wheat
Physiologia Plantarum, 1986The influence of plant population density on spectral distribution of light received by wheat (Triticum aestivum L. cv. Coker 797) seedlings was measured under field conditions, and effects of red and far‐red light on tillering and photosynthate partitioning were studied in controlled environments.

Photosynthate partitioning by phytoplankton in a New Zealand coastal upwelling system
Marine Biology, 1984The patterns of 14C incorporation into the major endproducts of photosynthesis were measured in the surface waters of a New Zealand coastal upwelling system between 8 March and 5 April, 1983. Overall, the majority of 14C was incorporated into protein (x=43.4%) followed by that into polysaccharide (x=33.3%), lipid (x=18.9%) and low molecular weight (LMW)

Effect of Irradiance on Partitioning of Photosynthate to Pea Root Nodules
Botanical Gazette, 1980Apparent N2 fixation and partitioning of recently formed 14C-photosynthate were compared in `Alaska' peas grown under 200, 500, or 800 μE·m-2·s-1 with plants grown under 500 μE·m-2·s-1 and exposed to 200, 500, or 800 μE·m-2·s-1 for 10 h. Plants grown under higher irradiance reduced more C2H2 and partitioned a greater fraction of translocated 14C ...

Photosynthate partitioning in diploid and autotetraploid barley (Hordeum vulgare)
Physiologia Plantarum, 1984Net rates of carbon assimilation per unit leaf area by fully expanded, vegetative leaves of diploid (2x) and autotetraploid (4x) barley (Hordeum vulgare L. cultivars OAC‐21 and Brant) were not significantly different (90% level) when measured under controlled environment conditions with air levels of CO2 and either 2 or 20% O2. Leaf thickness increased

Partitioning of photosynthates between growing panicle and vegetative parts before anthesis
Soil Science and Plant Nutrition, 1984Growth pattern and partitioning of photosynthates between growing panicles and vegetative organs during the development of young panicles were studied using two rice varieties differing in culm heights. 1) The growing panicle, leaf sheath of flag leaf, and culms grew simultaneously, but the culm displayed the highest growth rate.

Partitioning and Utilization of Net Photosynthate in a Nodulated Annual Legume
Journal of Experimental Botany, 1978The economy of carbon in nodulated white lupin (Lupinus albus L.) was studied in terms of consumption of net photosynthate in nitrogen fixation, in maintenance of respiration, and in the production of dry matter and protein. Net photosynthesis rose to a maximum in early fruiting and then fell abruptly due to shedding of leaves. Nodulated roots acquired

The Role of Hormones in Photosynthate Partitioning and Seed Filling
1987The movement of photoassimilates from sites of synthesis in leaf tissue (source) to the sites of net accumulation in a different tissue (sink) potentially can be regulated at numerous points. Regulation of the net flow of photoassimilates is an integrated process.

Photosynthate partitioning in Antarctic freshwater phytoplankton: in situ incubations
Freshwater Biology, 1990SUMMARY. 1. The distribution of 14C‐labelled photosynthate by phytoplankton in Sombre Lake, Antarctica, was measured during the spring/ summer period in 1987–88.2. Protein was the principal product of low‐light photosynthesis, with the proportion of polysaccharide and lipid increasing at higher radiation fluxes.
