Název v původním jazyce

Stomatal and pavement cell density linked to leaf internal CO2 concentration

Popis výsledku v původním jazyce

Background and Aims Stomatal density (SD) generally decreases with rising atmospheric CO2 concentration, C-a. However, SD is also affected by light, air humidity and drought, all under systemic signalling from older leaves. This makes our understanding of how C-a controls SD incomplete. This study tested the hypotheses that SD is affected by the internal CO2 concentration of the leaf, C-i, rather than C-a, and that cotyledons, as the first plant assimilation organs, lack the systemic signal. Methods Sunflower (Helianthus annuus), beech (Fagus sylvatica), arabidopsis (Arabidopsis thaliana) and garden cress (Lepidium sativum) were grown under contrasting environmental conditions that affected C-i while C-a was kept constant. The SD, pavement cell density(PCD) and stomatal index (SI) responses to Ci in cotyledons and the first leaves of garden cress were compared. C-13 abundance (delta C-13) in leaf dry matter was used to estimate the effective Ci during leaf development.
