I tried to identify and assess the C reservoirs in the pedo-sphere with C-source-sink-relations whereever it seemed possible and pointing to the poorly known rather enigmatic remainder. A special endeavor focussed on the chances and limitations of applying radio-carbon dating and stable isotope δ13 C measuring techniques.

Alteration of cotton source–sink relations with plant population density and mepiquat chloride
Field Crops Research, 2010Abstract Improvements in carbohydrate source–sink relations are needed to improve efficiency of yield formation in cotton ( Gossypium hirsutum L.). Most source–sink research has focused on leaf–boll relationships, with little study of vegetative storage reserves.

The Effect of Light Regime on Source–Sink Relations in the Shade-Enduring Ajuga reptans Plant
Russian Journal of Plant Physiology, 2004A quantitative approach to the evaluation of source–sink relations in Ajuga reptans plants grown under the forest canopy (shade plants) and on an open plot (sun plants) was worked out in terms of growth characteristics, CO2 exchange, and carbon balance.

Effects of Light Spectral Quality on Morphogenesis and Source–Sink Relations in Radish Plants
Russian Journal of Plant Physiology, 2001The accumulation of dry matter and the content of major phytohormones in the aboveground and underground plant parts, as well as light curves and the diurnal course of photosynthesis in the leaves were studied in radish (Raphanus sativusL.) plants of different ages that were grown under red (RL) or blue (BL) light.

Sunflower broomrape (Orobanche cumana) is a root holoparasitic plant causing major damage to sunflower (Helianthus annuus L.). Parasite infection initiates source-sink relations between the parasite (sink) and the host (source), allocating carbohydrates, water and nutrients to the parasite.

Root Development and Source-Sink Relations in Carrot,Daucus carotaL
Journal of Experimental Botany, 1980Physiological responses to root pruning were investigated by comparing 14C02 fixation rates, the partitioning of ""?-labelled assimilate, and soluble and insoluble carbohydrate levels in the leaves of carrot plants following the removal of some of the fibrous roots, or fibrous roots and part of the tap root. Root pruning reduced 14C02 fixation by 28-45%

Due to source‐sink relations, a redistribution of plastic compounds occurs between plant organs during their ontogeny. The inflorescence (ear, panicle) is a main sink in annual grasses during their reproductive period. Although source‐sink relations are genetically determined, such factors as weather conditions, mineral nutrition, and biologically ...

Source–sink relations and effects of post-anthesis canopy defoliation in wheat at low latitudes
The Journal of Agricultural Science, 1990SUMMARYSource–sink balance was studied by imposing different canopy defoliation treatments on wheat crops grown in Los Banos (Philippines) in 1985/86 and 1986/87, Sonora (Mexico) in 1972/73 and 1974/75 and New Delhi (India) in 1987/88. The crops were grown in replicated trials with optimum cultural management. Six defoliation treatments were imposed at

Source–sink relations in the “leaf–stem–root” system at the time of cambial growth were studied in two forms of silver birch: common birch (Betula pendula Roth var. pendula) and Karelian birch (B.pendula var. carelica (Merckl.) Hamet-Ahti). As compared with common birch, reduced sucrose content in the leaves of elongated (auxiblasts) and short ...

Root Development and Source-Sink Relations in Carrot,Daucus carotaL.
Journal of Experimental Botany, 1978Growth analysis and 14C02 feeding experiments have shown that the developing storage organ became an increasingly important sink for assimilates, accumulating 40% of the dry matter produced by the carrot plant within 9 weeks of sowing. The relative importance of each leaf in fixing and exporting 14C was assessed at two stages of development ...
