Source/Sink Relations of Abscising and Nonabscising Soybean Flowers [PDF]
Plant Physiology, 1984 The partitioning of recently fixed (14)C to setting and abscising flowers within the axillary raceme of ;Clark' isoline E1t soybeans (Glycine max L. Merr) was examined as a function of time after anthesis of individual flowers. In such racemes, the first four flowers showed a 17% abscission while the next four flowers showed 47% abscission.Source/sink ...

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

Agronomy, 2020 Potato tuber yields depend on nitrogen (N) supply, which affects source–sink relations. Transcriptome sequencing of the foliar source using a single field trial identified gene expression responsive to 180 kg N ha−1.

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.

The effects of rising atmospheric carbon dioxide on shoot-root nitrogen and water signaling
Frontiers in Plant Science, 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 ...
