Responses of stomatal density and distribution in leaves of Artemisia sphaerocephala krasch to drought stress under electric field treatment;

Under elevated CO2,the stomatal density increased slightly(P&.

Many studies have reported that increases in atmospheric CO 2 concentration ([CO 2]) lead to decreases in plant stomatal density (SD) and stomatal index (SI).

The lipid contents,specific surface areas and stomata density of two kinds of pine(Cedrus deodar and Pinus thunbergii) needles were determined simultaneously with the levels of polycyclic aromatic hydrocarbons(PAHs).

Taking thirty-six varieties of jujube as test material,stomata opens degree,stomata size and stomata density were observed.

Through comparison and observation on different kinds of Clivia miniata Regei water-cultivated Seedlings and soil-cultivated seedlings the change of stomata density,stomata size,stomata divergence of the leaves’ lower epidermis in the daytime,the result shows that Water-Cultivated Seedlings’stomata is obviously larger than that of soil-cultivated seedlings.

The changes of water-use efficiency and stoma density of Leymus chinensis along Northeast China Transect;

The leaf characters of stoma density, chlorophyll content, leaf shape and leaf pasture of garlic germplasm introduced from different part of China were studied.

It was found that each species had a special stoma density,and the stoma types were different between Angiopteris fokiensis Hieron and Archangiopteris henryi Christ et Gies,which could be considered as key characters to the genera and species of Angiopteridaceae.
