The effect of mannitol, glucose and sucrose on the stomatal behaviour of two desert species,Merremia aegyptia andM. dissecta has been studied. Stomatal opening did not uniformly depend on the decrease in turgor of the epidermal and subsidiary cells caused by the different osmotic potential of the sugars. Sucrose caused plasmolysis of the subsidiary cells only but this was not accompanied by the opening of the stomatal pore. InM. aegyptia, no plasmolysis was seen either in epidermal or… Expand

Stomatal responses towards neutral red uptake and particulate movement in some arid zone plants
TLDR
The neutral red uptake by the cells of the epidermal strip, coalescence of particles and their movement appear to be connected with the open/closed condition of the stomata. Expand

Role of epidermal cell turgor on stomatal regulation Lin isolated epidermal peelings of Citrullus colocynthis inn. (Schrad.)
Summary The role of epidermal cell turgor appeared to play a definite role in the regulation of stomatal pore in isolated epidermal peelings of C. colocynthis . Guard cells and their surroundingExpand
A CRITICAL EXAMINATION OF THE USE OF DETACHED EPIDERMIS IN STUDIES OF STOMATAL PHYSIOLOGY
TLDR
Epidermal strips from both species of Commelina are suitable for studies of stomatal responses to Hght and CO2 so long as they are incubated in a suitable medium and attempts are made to explain the difference in behaviour. Expand
The Role of the Epidermal Cells in the Stomatal Movements
TLDR
The passive stomatal movement eliciteed in this way has been denoted as “osmopassive”, in contrast to the long known passive movement caused by a change in turgor of the epidermal cells, and which has therefore been denoting as ”turgorpasslve”. Expand
The Effect of Epidermal Cell Water Potential on Stomatal Response to Illumination of Leaf Discs of Vicia faba
TLDR
It was found that the maximal aperture was obtained when epidermal cells were at about incipient plasmolysis and that any increase in their turgor pressure brought about a decrease in stomatal aperture. Expand
FURTHER OBSERVATIONS OF CATION‐STIMULATED STOMATAL OPENING IN ISOLATED EPIDERMIS
TLDR
It is tentatively concluded that active transport of monovalent cations into guard cells might explain the CO2-independent light responses of stomata, but not their light-independent CO2 responses. Expand
Guard-Cell Starch Retention and Accumulation in the Dark
TLDR
In some species exogenously supplied glucose-1-phosphate or sucrose can serve as a precursor to guard-cell starch without the aid of mesophyll or bundle cells. Expand

TLDR
The prominent hypotheses conderning stomatal operation are discussed in relation to present knowledge and a simplified scheme shows the probable biochemical changes involved in opening and closing Vicia faba stomata. Expand
