Field Crops Research, 2019 Maize (Zea mays, L.) kernel weight (KW) is regulated by the source-sink relationship at the early grain-filling period, when potential kernel size is defined, and at the effective grain-filling period, when final KW is established.

Yield and source/sink relations of spring wheat cultivars
Field Crops Research, 1989Abstract Spikelets from one side of the ear were completely removed at flowering (treated ear) to demonstrate the different responses of old and new spring wheat cultivars to source/sink manipulation. The concepts of potential ear productivity (doubled yield of the treated ear) and potential protein content in the remaining half of the ear were ...

Investigating Source-Sink Relations in Cassava by Reciprocal Grafts
Experimental Agriculture, 1982SUMMARYThe relation between source potentials and sink capacities of four cassava (Manihot esculentaCrantz) varieties with different characteristics was investigated by means of reciprocal grafts. There were marked differences in the sink capacities (average stock effects) and source potentials (average scion effects) of the varieties.

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.

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 ...

The Role of the Transport System in the Control of the Source–Sink Relations in Pinus sylvestris
Russian Journal of Plant Physiology, 2003Morphophysiological correlations were studied in medium-aged (20- to 60-year-old) Scots pine trees under the northern taiga conditions. Under various ecological conditions, pine trees developed a well-balanced structure, with close linear relationships between needle and root weight and their cross-section areas in all components of the continuous ...

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.

Source‐Sink Carbon Relations in Two Panicum Coloratum Ecotypes in Response to Herbivory
Ecology, 1991Population samples of an African C4 grass, Panicum coloratum L., were collected from two locations in the Serengeti Grasslands varying in grazing intensity, one a high—grazing location (GA = grazing—adapted), the other a low—grazing location (NGA = nongrazing—adapted).

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.
