Vývoj průduchů dvouděložných rostlin: vliv faktorů prostředí
KALISTOVÁ, Tereza
Stoma are microscopic structure in plant epidermis consisted of two guard cells and a pore between them. Their development is influenced by internal processes and different environmental factors as light, water availability or concentration of CO2. Carbon in CO2 has two stabile isotopes,12C and 13C, which have different weight and concentration in atmosphere. The 13C abundance (13C) in leaf tissue reflects the environmental condition experienced during the leaf live span. Here I studied: i) development of epidermal cells (primarily of stomata) during first true leaf ontogeny in Lepidium sativum and Arabidopsis thaliana and ii) effect of milling the dry leaf tissue in microtubes on 13C.
