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 ...

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.

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

Abstract In semi-arid and arid environments, clonal plants occasionally appear in ring patterns. There is a general agreement that this pattern forms when ramets grow radially, leaving a dead centre where the parent plant once was. Nevertheless, there is still some controversy over the actual causes of this dieback and how water source–sink relations

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.

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 ...

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.

Two opposing hypotheses have been presented to explain reduced tree growth at the treeline, compared with growth in lower elevation or lower latitude forests: the carbon source and sink limitation hypotheses. The former states that treeline trees have an unfavorable carbon balance and cannot support growth of the magnitude observed at lower elevations ...

[Regulation effects of various training modes on source-sink relation of cotton].
Ying yong sheng tai xue bao = The journal of applied ecology, 2008With the removal of vegetative branches plus the maintenance of early fruiting branches as the control, the effects of various training modes on the source-sink relation of field-grown cotton were examined in 2005 and 2006. The results showed that compared with the control, either the removal of vegetative branches plus the removal of early fruiting ...

Abstract. Herbaceous C3 plants grown in elevated CO2 show increases in carbon assimilation and carbohydrate accumulation (particularly starch) within source leaves. Although changes in the partitioning of biomass between root and shoot occur, the proportion of this extra assimilate made available for sink growth is not known.
