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

Dissolved Hydrocarbons and Related Microflora in a Fjordal Seaport: Sources, Sinks, Concentrations, and Kinetics [PDF]
Applied and Environmental Microbiology, 1981 The continuous addition of toluene as a solute of treated ballast water from oil tankers into a well-defined estuary facilitated the study of the dynamics of dissolved hydrocarbon metabolism in seawater. Most rates of toluene oxidation were in the range of 1 to 30 pg/liter per h at 0.5 μg of toluene per liter.

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

Alterations in Source-Sink Patterns by Modifications of Source Strength [PDF]
, 1980 Bean plants, trimmed to a simplified “double source, double sink” translocation system (the paired primary leaves serving as the double source and the paired lateral leaflets of the immature first trifoliate leaf as the double sink) were used to study ...

Growth and physiological responses of maize inbreds and their related hybrids under sufficient and deficient soil nitrogen [PDF]
Catrina: The International Journal of Environmental Sciences, 2020 In this study, the effects of sufficient and deficient soil N on the growth and physiology performance of maize inbreds (B73, Mo17, Sids7 and Sids63) and hybrids (B73 × Mo17 and Sids7 × Sids63) were simultaneously monitored. This was done at rapid growth

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.

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 ...

Alteration of Wheat Source-Sink Relation by Nitrogen and Spikelet Removal
Tekirdağ Ziraat Fakültesi Dergisi, 2023 The source and sink relationships determine the amount and distribution of biomass in plants. Field and laboratory experiments were conducted to study the effect of nitrogen rate and spikelet removal on seed yield and germination traits of wheat. The field experiment was conducted employing sink manipulation (no spikelet removal and ½ spikelet removal)
