Sink regulation of photosynthesis.
The concept that photosynthetic flux is influenced by the accumulation of photo-assimilate persisted for 100 years before receiving any strong experimental support. Precise analysis of the mechanisms of photosynthetic responses to sink activity required the development of a battery of appropriate molecular techniques and has benefited from contemporary interest in the effects of elevated CO2 on...
متن کاملPhotosynthesis and Carbon Partitioning / Source-sink Relationships
Photosynthesis is one of the principle biochemical processes underpinning plant growth and development. Because of its basic nature, it is intimately involved with reproductive growth and determining crop yields. Photosynthesis of a crop canopy can be broken down into three components: 1) leaf area development, 2) photosynthetic rate per leaf area, and 3) partitioning assimilates between vegeta...
متن کاملMolecular determinants of sink strength.
The manipulation of sink to source relations has been subject to extensive plant breeding programs aiming to improve harvest index and thereby crop yield. The introduction of molecular and biochemical tools has enabled scientists to investigate the underlying principles. This has opened up the fascinating possibility of identifying molecular determinants of sink strength and to further increase...
متن کاملAlterations in source-sink patterns by modifications of source strength.
Bean plants, trimmed to a simplified "double source, double sink" translocation system (the paired primary leaves serving as the double source and the paired lateral leaflets of the immature first trifoliate leaf as the double sink) were used to study the magnitude and short-term time course of change in the allocation ratio (partition ratio) of assimilates translocated from the labeled primary...
متن کاملrole of ear photosynthesis and transpiration in sink size determination in barley
in order to investigate the contribution of ear photosynthesis and cytokinin in determining grain sink size, a pot study was conducted during january to june 2005 in cereal glasshouse of faculty of agriculture of karaj, iran. experiment was conducted in a complete randomized design with a factorial arrangement of two factors, three replications and four pots in each plot. factors included culti...
