Investigating phloem transport dynamics in Arabidopsis through compartmental modelling of positron emission tomography data [PDF]
Plant MethodsBackground Phloem is the long-distance transport tissue of vascular plants in which photoassimilates are distributed from sources (e.g., leaves) to sinks (e.g., roots, fruits).

Effects of Population Regulation on the Source–Sink System of Hybrid Wheat Jingmai 6
Agronomy, 2022 Hybrid wheat is considered to be one of the main ways to greatly improve the wheat yield in the future, and population construction is an important factor affecting their yield heterosis formation.

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 ...

Cycas micronesica Stem Carbohydrates Decline Following Leaf and Male Cone Growth Events
Plants, 2020 The growth of synchronized leaf flushes or male cones on Cycas trees is an ephemeral event, and non-structural carbohydrates (NSCs) are likely deployed from stem and root storage tissues to support their construction. The relationships among various stem

N-partitioning, nitrate reductase and glutamine synthetase activities in two contrasting varieties of maize [PDF]
Pesquisa Agropecuária Brasileira, 2001 In order to identify useful parameters for maize genetic breeding programs aiming at a more efficient use of N, two maize varieties of contrasting N efficiency, Sol da Manhã NF (efficient) and Catetão (inefficient) were compared. Experiments were carried

Agronomic performance of late-season rice in South China
Plant Production Science, 2018 Improving rice yields is critical for global food security. China is a major rice-producing country having two rice cropping systems, i.e. single-season rice cropping system and a double-season system with both early- and late-season rice.

International Journal of Agronomy, 2019 The source-sink ratio experimental manipulation has helped to define whether a crop is limited by source or sink or co-limited by both. There is no evidence in triticale of source-sink manipulations effects on yield and yield components.
