Abstract
Tipul morfologic anomocit al aparatelor (complexelor) stomatice caracterizează epiderma abaxială şi adaxială a laminei frunzei la 5 specii de Clematis L. Densitatea stomatelor este specifică şi variază, în anul secetos 2007, de la 119,05 stomate/mm2 la specia Clematis vitalba până la 182,05 stomate/mm2 la specia C.tangutica. Grosimea medie mai mare a laminei frunzei şi prezenţa stomatelor în epiderma adaxială a laminei frunzei evidenţiază speciile mai rezistente la secetă
As a result of quantitative anatomic study of leaf blade of 5 species of genus Clematis L., is established that anomocytic morphological type of stomatal apparatus (complex) is characteristic for the abaxial and adaxial epidermis. Stomatal density of leaf epidermis of clematises is specific, but varies in different years. The density of leaf stomata characterizes every species and varies, in drought 2007 year, from 119,05/mm2 at species Clematis vitalba to 182,05 stomata/mm2, at species C.tangutica. The greater average thickness of leaf blade and present of stomata in adaxial epidermis of leaf blade evidence more drought resistant species of clematises.
