Investigations of Source-Sink Relations in Cassava Using Reciprocal Grafting
Experimental Agriculture, 1990SUMMARYSource-sink relations in cassava were investigated following reciprocal grafting among three cultivars of different yield groups. Both rootstock and scion had significant effects on net assimilation rate and tuber yield, demonstrating that both sink capacity and source activity are important in achieving maximum tuber yield.

Alteration of Wheat Source-Sink Relation by Nitrogen and Spikelet Removal
Tekirdağ Ziraat Fakültesi Dergisi, 2023The source and sink relationships determine the amount and distribution of biomass in plants. Field and laboratory experiments were conducted to study the effect of nitrogen rate and spikelet removal on seed yield and germination traits of wheat. The field experiment was conducted employing sink manipulation (no spikelet removal and ½ spikelet removal)

Source-Sink Relations: The Role of Sucrose
1996We examine the idea that sucrose plays a central role in control of plant growth beyond that of substrate and product. The extended hypothesis we discuss is that sucrose can regulate source metabolism by down-regulating genes encoding proteins involved with photosynthesis, and sink metabolism by up-regulating genes encoding proteins involved with ...

Sex-specific physiology and source-sink relations in the dioecious plant Silene latifolia
Oecologia, 1996Differences in reproductive demands between the sexes of dioecious plants could cause divergence in physiology between the sexes. We found that the reproductive effort of female Silene latifolia plants increased to more than twice that of male plants or female plants that were prevented from setting fruit by lack of pollination after 4 weeks of ...

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%

Plant and Cell Physiology, 2022
Abstract Changes in climate conditions can negatively affect the productivity of crop plants. They can induce chloroplast degradation (senescence), which leads to decreased source capacity, as well as decreased whole-plant carbon/nitrogen assimilation and allocation. The importance, contribution and mechanisms of action regulating source-

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.

Records of Source—Sink Relations by Means of Respiration Measurements
Journal of Experimental Botany, 1989A method for recording respiration rates of attached single soybean pods is described. By means of such records source-sink relations can be observed over an extended period of time if photosynthesis of leaves is recorded simultaneously. It is shown that there are direct influences on respiration, such as changes in temperature and indirect effects ...

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 ...

Engineering source-sink relations by prime editing confers heat-stress resilience in tomato and rice
CellA 2°C climate-warming scenario is expected to further exacerbate average crop losses by 3%-13%, yet few heat-tolerant staple-crop varieties are available toward meeting future food demands. Here, we develop high-efficiency prime-editing tools to precisely knockin a 10-bp heat-shock element (HSE) into promoters of cell-wall-invertase genes (CWINs) in ...
