  • The carbon dioxide leakage from chambers measured

    2000-4-1In plant chamber studies, if CO 2 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 CO 2 leakage be determined. Sulfur hexafluoride (SF 6) was introduced into the chambers as a tracer gas to estimate leakage rates.Chamber leakageCited by: 16
