Two experiments were conducted in a greenhouse measuring root-zone respiration (RZR1, RZR2) in addition to four in a CO2 gas-exchange cuvette (C1, C2, C3, C4).
The proportion of ectomycorrhizal root tips showed a significant interaction between soil inoculation treatment and greenhouse measured glucosinolate concentrations, as seen for seedling biomass (Table 4, Fig. 3B).
Based on experimental CO2 concentrations in the greenhouses measured for all experiments, δ13C of the air ranged between −7.81‰ (E4) and −9.17‰ (E1).
Todd Stern, the chief American climate negotiator, noted several months ago that some people "across the pond" did not fully understand how difficult it was to move the U.S. Congress to approve economy-wide greenhouse gas measures.
European justice ministers meeting in Luxembourg approved the greenhouse gas measures, which oblige airlines, regardless of nationality, that land or take off from an airport in the European Union to join the emissions trading system starting on Jan . 1 , 2012
China has recently overtaken the United States as the world's largest emitter of greenhouse gases, measured in an absolute sense.
Carbon offset, any activity that compensates for the emission of carbon dioxide (CO2) or other greenhouse gases (measured in carbon dioxide equivalents [CO2e]) by providing for an emission reduction elsewhere.
Where sphericity assumptions were violated, Greenhouse-Geisser measures are reported.
Vanillin content of mature vanilla beans obtained from the greenhouse was measured using HPLC after acid hydrolysis.
Heights of T2 plants from control and SBE RNAi4.1 lines growing in greenhouse were measured at 20, 40, 60, 80, 100 and 120 days after sowing.
