Project

The medullosan pteridosperms and cordaites from the Permo-Carboniferous of the Bohemian Massif (A study of the cuticles and fertile organs) (GA205/05/2034)

This project is a continuation of previously funded studies on cuticles of Permo-Carboniferous pteridosperm and cordaite cuticles. Although over 100 species Massif, only 35 species are known to have preserved cuticles. Four...

Heterogeneity of leaf cuticular membrane (ME 368)

Permeability of intact and isolated leaf cuticle for photosynthetic herbicides in a two-dimensional scale and heterogeneity in chemical composition of cuticular wax will be investigated. We plan to apply chlorophyll flourescence imaging tech...

Cordaitalean and pteridosperm cuticular analysis and their "in situ" prepollen (GAP210/10/0232)

cordaitalean cuticles have not yet been studied, and these will also be dealt using cuticles. A study of ?in situ? prepollen from cordaitalean and pteridosperm plant? reconstructions. Finally, dispersed cordaitalean cuticles

Stomata coordination of development, evolution of CO2 sensing and carbon acquisition (GA18-14704S)

and the atmosphere. Both cuticle and stomata represent evolutionary innovations in plant that cuticle, and wax on its surface, represent a gate for CO2 and other environmental and permeability of cuticle (wax) is linked to...

Epicuticular wax on stomatal guard cells ESEM, analytical and physiological (IAA6051002)

We found in our previous investigation that the composition and/or structura of wax in guard cell cuticle is different from thet on the other epidermal cells. This conclusion was drawn from observations of uncoated leaf and cuticle ...

Epidermal structures of medullosan pteridosperms from the Upper Carboniferous of the Bohemian Massif (GA205/00/1535)

Over 60 species of Carboniferous medullosan pteridosperms are reported from the intermontane basins of the Bohemian Massif Cuticles, which are an important diagnosticfeature because they preserve the leaf epidermal patterns, are not known fr...

An investigation of ferns of the Czech Cenomanian based on microscopical study of their anatomy (GA205/03/1267)

A review of the ferns from the Czech Cenomanian is the main object of this project based on microscopical study of their anatomy (spores, sores and cuticles). Fine preservation of fossil plants allowes to use the method "spores in situ". The...
