The source in the plant is responsible for synthesising the sugars required for plant growth. The sinks in the plants use the sugars for immediate use and store the rest for future metabolic needs. Example: The leaves act as a source when photosynthesising. Seeds, fruits, flowers, roots, and storage organs act as sinks in fully grown plants.

Oct 14, 2015 · However, modern genetic approaches may now be used to alter source and sink activity with greater elegance. Table 1 outlines a range of source:sink manipulations and summarizes their results. Broadly speaking, increasing either source or sink may increase growth, suggesting that both can limit growth to a certain extent.

To describe where an essential resource is taken up or synthesized, and where it is used in a plant, biologists use the terms “source” and “sink”. A source is a location in a plant where a resource is taken up (ex. water and nutrients) or synthesized (glucose). A sink is a location where a resource is used. Fruit & Nut Research ...
Oct 31, 2023 · The points of sugar delivery, such as roots, young shoots, and developing seeds, are called sinks. Seeds, tubers, and bulbs can be either a source or a sink, depending on the plant’s stage of development and the season. The products from the source are usually translocated to the nearest sink through the phloem.
Sep 25, 2018 · Sink activity is photoassimilate use and storage. Belowground organs of plants (e.g. roots and rhizomes) are sinks during plant growth since they cannot perform photosynthesis. Some organs are both a source and sink. Leaves are sinks when growing and sources when photosynthesizing. Rhizomes are sinks when growing but become sources in the ...
A source is any structure in a plant that either produces (like a leaf) or releases (like a storage bulb) sugars for the growing plant. A sink is any location where sugar is delivered for use in a growing tissue or storage for later use. Growing tissues might include apical and lateral meristems or developing leaves, flowers, seeds, and fruits ...

Feb 17, 2017 · The definition of terminologies used in source–sink interaction. The concepts of source and sink in plants were first proposed by Mason and Maskell (1928). Source is a material producer and exporter, and sink is a material importer and consumer (Foyer and Paul, 2001).
