Which side of the leaf has more stomata adaxial or abaxial?

In general, stomatal densities are higher in the abaxial than in the adaxial epidermis of most species, except in the Graminae where there are more or less equal densities on both surfaces.

How do you calculate stomatal density?

You can calculate this using the formula area = πr2, when you have measured the true radius of the field of view (r). g Count the stomata visible in each of three areas of the impression.

Do taller trees have higher stomatal density?

Our data found did not prove or disprove our hypothesis. Although we did not find what we were expecting, we found that there was no overall difference in data. The number of stomata on each leaf, throughout different heights on the plant had no significant difference from one another, meaning no change.

Do Xerophytes have a high stomatal density?

The stomata on such xerophytes may be in deep pits or in the folds of leaves. We would guess that xerophytes have a lower stomatal density than mesophytes.

Is there a stomata on the adaxial leaf?

Stomatal density and distribution on the leaf surfaces varied greatly among species. Most of the creeping herbaceous species had stomata on both the adaxial and abaxial leaf surfaces (amphistomatous); however, lianas had no stomata on the adaxial leaf surface.

How are stomatal density and epidermal cell density related?

A positive correlation between stomatal density and epidermal cell density was found on the abaxial/adaxial leaf surfaces of the examined species. This suggests that there is a developmental similarity among vine species in which stomata are developed with differentiation of epidermal cells on the leaf surface.

How are stomata arranged on an abaxial surface?

The differences in stomatal density between surfaces are considerable, with much higher frequencies on abaxial surfaces. Abaxial stomatal density for the family is (78 mm -2 ), this is greater than the adaxial average (25 mm -2 ). Stomata are arranged without regularity on a whole leaf.

Which is the highest density of Allium stomata?

Allium has the highest stomatal frequencies of all species in this study, with an abaxial average density of 143 mm -2. The lowest densities are found in Scilla mischtschenkoana with 27 mm -2 on adaxial and 20 mm -2 on abaxial surfaces, respectively. The difference in frequency between both surfaces is often minor.
