Photosynthetica, 2012 Leaf canopy plays a determining role influencing source-sink relations as any change in source activity (photosynthesis) affects sink metabolism. Defoliation (removal of leaves) influences growth and photosynthetic capacity of plants, remobilizes carbon and nitrogen reserves and accelerates sink metabolism, leading to improved source-sink relations.

Metabolite Signals Regulate Gene Expression and Source/Sink Relations in Cereal Seedlings [PDF]
Plant Physiology, 1994 Our knowledge of the genetic structures and regulatory mechanisms active during cereal seedling development has increased dramatically in recent years. For this reason, a more integrated view of the molecular aspects of seedling development and physiology is needed. This review presents the Carbon Metabolite Signal Hypothesis, which attempts to explain

How periodic growth pattern and source/sink relations affect root growth in oak tree seedlings [PDF]
Journal of Experimental Botany, 2006 Seedlings of Quercus pubescens were grown in root boxes to study the growth pattern of the root system in relation to shoot development. Shoot growth was typically rhythmic. Root elongation was also periodic, in contrast to several previous reports on other Quercus species. Both taproot and lateral root elongation were depressed during expansion of the

Control of Kernel Weight and Kernel Water Relations by Post-flowering Source-sink Ratio in Maize [PDF]
Annals of Botany, 2003 The maize (Zea mays L.) kernel undergoes large changes in water content during its development. Whether such changes regulate the pattern of kernel development or are simply a consequence of it has not yet been established because other factors, such as assimilate supply, can also affect the rate and duration of kernel growth.

Integrated Land Use Change Related Carbon Source/Sink Examination in Jiangsu Province [PDF]
Land, 2021 Carbon emission (CE) threatens global climate change severely, leading to the continuous strengthening of the greenhouse effect. Land use changes can greatly affect the ecosystem carbon budget and anthropogenic CE. Based on the land use grids, net ecosystem productivity (NEP), energy consumption-related CE, this study employed various methods to ...

Source-Sink Relations in Maize Mutants with Starch-Deficient Endosperms [PDF]
Plant Physiology, 1982 Partitioning and translocation of photosynthates were compared between a nonmutant genotype (Oh 43) of corn (Zea mays L.) and two starch-deficient endosperm mutants, shruken-2 (sh2) and brittle-1 (bt1), with similar genetic backgrounds. Steady-state levels of (14)CO(2) were supplied to source leaf blades for 2-hour periods, followed by separation and ...

Bunch Weight Determination in Relation to the Source-Sink Balance in 12 Cavendish Banana Cultivars [PDF]
Agronomy, 2022 This study was carried out to compare bunch weight determination in relation to the source-sink balance in a selection of 12 Cavendish banana cultivars. Fruit number and individual fruit weight are the main bunch weight components. The fruit number depended on the growth potential during floral induction, which we estimated according to the active leaf

The effects of rising atmospheric carbon dioxide on shoot-root nitrogen and water signaling. [PDF]
, 2013 Terrestrial higher plants are composed of roots and shoots, distinct organs that conduct complementary functions in dissimilar environments. For example, roots are responsible for acquiring water and nutrients such as inorganic nitrogen from the soil ...
