The Study of Source-Sink Relations by Comparison of Weight and Grain in the Modern and Old Wheat Cultivars [PDF]
Ikufīziyuluzhī-i Giyāhān-i Zirā̒ī, 2017 Seed filling in wheat is controlled by the availability of substrate (source strength), the capacity of the organs to utilize it for seed growth (sink strength).

Corn Grain Weight: Dependence upon Nitrogen Supply and Source-Sink Relations [PDF]
Kansas Agricultural Experiment Station Research Reports, 2021 From a yield component perspective, final grain yield in corn (Zea mays L.) is the result of the number of grains per unit area and their final grain weight. The understanding of grain weight parameters, the rate and duration of grain growth, is critical to improve our rational design of management practices and breeding strategies.

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.

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 ...

Effect of changed source/sink relations on proteolytic activities and on nitrogen mobilization in field-grown wheat (Triticum aestivum L.) [PDF]
, 1979 Nitrogen mobilization and the pattern of proteolytic enzymes were investigated in leaves and glumes of field-grown winter wheat (Triticum aestivum L.) during maturation. Source/sink relations were changed by removal of the ear, the flag leaf or the lower

Triose phosphate utilization in leaves is modulated by whole-plant sink–source ratios and nitrogen budgets in rice [PDF]
, 2023 International audienceTriose phosphate utilization (TPU) is a biochemical process indicating carbon sink-source (im)balance within leaves. When TPU limits leaf photosynthesis, photorespiration-associated amino acid exports probably provide an additional ...

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

Source-sink relationship in Hausa potato [PDF]
, 2022 Fresh tuber yield of Hausa potato [Solenostemon rotundifolius (Poir) J.K. Morton] is generally low in Nigeria, perhaps, due to a lack of balance between the source and the sink.

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
