  • The carbon dioxide leakage from chambers measured

    In plant chamber studies, if CO2 leaking from a chamber is not quantified, it can lead to an overestimate of assimilation rates and an underestimate of respiration rates. Consequently, it is critical that CO2 leakage be determined. Sulfur hexafluoride (SF6) was introduced into the chambers as a tracer gas to estimate leakage rates. Chamber leakageCited by: 16
