What is the source-sink relationship?

Source organs provide a net uptake of resources whilst sink organs have a net drawdown of resources. Molecular mechanisms regulate the relationship between sources and sinks. These molecular mechanisms include carbon- and nitrogen-containing metabolites, plant hor- mones and genes.

What is source-sink?

Sink and Source are terms used to define the flow of direct current in an electric circuit. A sinking input or output circuit provides a path to ground for the electric load. A sourcing input or output provides the voltage source for the electric load.

What is the importance of source-sink relationship?

Source-Sink Relationships in Crop Plants and Their Influence on Yield Development and Nutritional Quality. For seed crops, yield is the cumulative result of both source and sink strength for photoassimilates and nutrients over the course of seed development.

What is source and sink mechanism?

Within a plant, the “source” may be defined as a photosynthesizing tissue or organ with export of carbon skeletons, the “sink” as one requiring import of carbon, the “sink strength” as the ability of a tissue or an organ to mobilize photo-assimilates, the “sink capacity (or sink size)” as the capacity of a tissue or …

What is the definition of sink source relationship?

Sink source relationship • sink source relationship is a process involved in translocation of photosynthetic products in plants 3. Definition • In plants , there is considerable movement of various substances from regions of supply (source) to region of utilization or storage (sink). 4.

Which is the best description of source sink dynamics?

Source–sink dynamics. Source–sink dynamics is a theoretical model used by ecologists to describe how variation in habitat quality may affect the population growth or decline of organisms.

How are sink and source used in a circuit?

Sink and Source are terms used to define the flow of direct current in an electric circuit. A sinking input or output circuit provides a path to ground for the electric load. A sourcing input or output provides the voltage source for the electric load.

How are sink organs related to source organs?

Source organs provide a net uptake of resources whilst sink organs have a net drawdown of resources. Molecular mechanisms regulate the relationship between sources and sinks. These molecular mechanisms include carbon‐ and nitrogen‐containing metabolites, plant hormones and genes.
