Source-sink Relationships in Soybean
It is interesting to know in details about the source-sink relationships in soybean. Here, it was tried to elaborate the source and sink concepts and the dependence to each other. It is important to know the relationships perspective to productivity of soybean. As the soybean yield is not high enough, it is of special interest. Changes in leaf photosynthesis with the variation of source and env...
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 کاملEnvironmental Characteristics of Desert Tortoise (Gopherus agassizii) Burrow Locations in an Altered Industrial Landscape
– In the Colorado Desert of California, the western distributional limit of the desert tortoise (Gopherus agassizii) occurs in the Whitewater Hills of the southeastern San Bernardino Mountains. Much of the area has been developed for wind energy generation and tortoises often live in association with altered industrial landscapes. Natural habitat in the area was characterized by a sharp transit...
متن کاملPlant sink-source relationships and carbon isotopic labeling techniques . Taher Barzegar* and Fatemhe Nekounam
The concept of source and sink strength is presently well-recognized and accepted by the scientific community as a pertinent approach describing the mechanisms of carbohydrate partitioning into the different and competing organs at a whole plant or canopy scales. Sink–source relationships have a clear role in the size of sink organs. Besides the effect on organ size, sink/source ratio might also...
متن کاملChanges in Sink–source Relationships during Shoot Development in Olive
ABSTRACT. Net photosynthesis, dark respiration, chlorophyll and carbohydrate content, and leaf and shoot growth in plants of evergreen olive (Olea europaea L.) grown under controlled conditions were measured to assess changes in carbon balance during leaf development of the 6th, 12th, and 16th node (from the base, first flush) through expansion to maturity. Shoot and leaves expanded in a sigmoi...
