Effects of elevated atmospheric CO2 on spore capsules of the moss Leptobryum pyriforme

Abstract

Growing Leptobryum pyriforme (Hedw.) Wilson under ten times ambient atmospheric CO2 concentrations showed that, while stomatal density and index decreased under elevated atmospheric CO2, the overall number of stomata per spore capsule remained unaltered. Capsule length increased, while the size of stomata and epidermal cells decreased. This study suggests that stomatal frequency measures used to investigate the influence of varying levels of atmospheric CO2 on angiosperms and gymnosperms may result in misleading conclusions when applied to bryophytes if considered in isolation from growth responses.
