On the "well-mixed" assumption and numerical 2-D tracing of atmospheric moisture [PDF]

Atmospheric Chemistry and Physics, 2013
Atmospheric water vapour tracers (WVTs) are an elegant tool to determine source–sink relations of moisture "online" in atmospheric general circulation models (AGCMs).

Illuminating Long-lived Cycas Cotyledons Reduces Sink Demands on Megagametophytes during Initial Seedling Growth

HortScience
Cycas megagametophyte resources are translocated to developing seedlings through the persistent green cotyledons. The source activities of cotyledons and megagametophytes following germination are not adequately understood. The decline in megagametophyte

Possibilities for carbon sequestration in Irish forests. COST E21 Workshop. Contribution of forests and forestry to mitigate greenhouse effects. Joensuu (Finland). 28-30 Sep 2000 [PDF]

Biotechnologie, Agronomie, Société et Environnement, 2000
Ireland has a rapidly expanding forest estate which covers some 9/ of the land area. It is government policy to increase this to 17/ by the year 2030. Preliminary studies suggest that forestry activities have the potential to contribute significantly to ...

Monitoring and reporting carbon stocks and fluxes in Dutch forests. COST E21 Workshop. Contribution of forests and forestry to mitigate greenhouse effects. Joensuu (Finland). 28-30 Sep 2000 [PDF]

Biotechnologie, Agronomie, Société et Environnement, 2000
Global forests play an important role in the global carbon cycle. At this moment they absorb about 25/ of the emission of carbon dioxide. This aspect has initiated research into the possibilities of enhancing and maintaining this role of global forests ...

Forests and the national greenhouse gas inventory of Germany. COST E21 Workshop. Contribution of forests and forestry to mitigate greenhouse effects. Joensuu (Finland). 28-30 Sep 2000 [PDF]

Biotechnologie, Agronomie, Société et Environnement, 2000
Since 1995, experiences have been gathered with the calculation of National Greenhouse Gas Inventories in Germany. Because only marginal changes of the total forested area occur in Germany, relevant changes of the balance of greenhouse gases in the ...

The impact of growth stimulators and retardants on the utilization of reserve lipids by sunflower seedlings

Regulatory Mechanisms in Biosystems, 2017
Using growth stimulators and anti-gibberillin preparations of different chemical compounds, we created different pressures in the coordinate covalent bond systems during germination of sunflower seeds.
