"Greenhouse conditions" refers to an environment that is controlled and artificially created to promote plant growth, just like a greenhouse.
Full definition
The authors acknowledged previously published research on downy mildew in basil, but noted that this study demonstrated for the first time that younger basil plants appear to be more susceptible than older plants to downy mildew
under greenhouse conditions.
[10] Earlier still, a 200 - million year period of intermittent, widespread glaciation extending close to the equator (Snowball Earth) appears to have been ended suddenly, about 550 million years ago, by a colossal volcanic outgassing which raised the CO2 concentration of the atmosphere abruptly to 12 percent, about 350 times modern levels, causing
extreme greenhouse conditions and carbonate deposition as limestone at the rate of about 1 mm per day.
109 - Kenneth, the grunt work is setting up specific
greenhouse conditions where climate and ecological variables can be isolated, along with the individual tree species.
Clearly, (then again perhaps not clearly) other factors beside atmosphere carbon influence Earth temperatures, other factors that are instrumental in bringing about Icehouse conditions at one time followed
by Greenhouse conditions at other times.
The question is whether the Comanche outcrops are an anomaly or are representative of the vast stores of carbon and oxygen that would be predicted by warm,
wet greenhouse conditions on Mars.
The team compared plant features such as the amount of tillers and grains per spike to those grown under
regular greenhouse conditions, finding that often the speed bred plants came out on top.
[65] Earlier still, a 200 - million year period of intermittent, widespread glaciation extending close to the equator (Snowball Earth) appears to have been ended suddenly, about 550 Ma, by a colossal volcanic outgassing that raised the CO2 concentration of the atmosphere abruptly to 12 %, about 350 times modern levels, causing
extreme greenhouse conditions and carbonate deposition as limestone at the rate of about 1 mm per day.
Finally, we use an efficient climate model to expand our estimated climate sensitivities beyond the Cenozoic climate range to snowball Earth and
runaway greenhouse conditions.
First, they grew the different rice lines
in greenhouse conditions and showed that the modified Brazilian and African rice did indeed show higher levels of galactinol than the unmodified control rice.
The second study examined the impact of increased nutrient supply in combination with «
greenhouse conditions,» a combined increase of temperature and carbon dioxide concentrations.
Importantly, on - going ecological monitoring initiated by Thoreau and Leopold will help to clarify the complexities of this system under future change, and to illuminate plant phenological responses in experimental warming plots and under
greenhouse conditions.
«Ultimately, we find that during intervals of high zircon production we have
greenhouse conditions, and as zircon production diminishes, we see a shift into our icehouse conditions.»
Fakhri Bazzaz, a plant physiologist at Harvard, has found that carbon dioxide - enriched air accelerates short - term plant growth, but his studies were carried out under controlled
greenhouse conditions and are difficult to translate to a larger scale.
