Micromorphological tepal epideramal patterns study of Delphinium L. species in IRAN

In this research the outer tepal of 28 species of Delphinium were micromorphologically studied using Scaning Electron Microscope (SEM). Tepals were examined through electronic microscope observations regarding hair existing, hair form, hair density and tepal epidermal patterns and a separate table was prepared. In this study results showed the species were classified in two groups of hairy and hairless, and regarding the hair diversity in four groups of strigose, villous, crispate and hooked, also tepal epidermal patterns categorized into six groups including the papillae, cup shape, rugose, striate, granular and striate rugose. These results indicate that species complex of D. crispulum, D. elbursense, D. speciosum and D. dasycarpum show differences regarding the type of tepal hair and tepal epidermal patterns. Also, the micromophological study of tepal epidermal pattern, confirmed the separation of D. saniculifolium from D. aquilegifolium and D. tuberosum from D. cyphoplectrum.
