Trichome micromorphology
-
Macro- and micromorphological features of fruit and seeds belonging to 12 taxa genera of Matthiola W.T.Aiton were studied via stereomicroscope and scanning electron microscope. In macromorphological studies, the following variables were investigated: the shape, size, and color of fruit and seeds; the length of fruiting pedicel; the structure of the median vein; stigma (horns); and trichome properties and density in fruit. In micromorphological studies, the presence or absence of seed wings, seed coat pattern in disc and wing, and epidermal cell shape in disc and wing were determined.

Trichomes of 35 species of the genus Convolovulus and one species of the genus Calystegia (C. sepium) were investigated using light and scanning electron microscopy. The trichomes show a great variation, which provides valuable data for sections and species delimitation in Convolvulus. Trichomes of Convolvulus are nonglandular, simple, and basifixed or rarely asymmetrically medifixed. Characters of taxonomic interest were the degree of curviness (straight to spiral), orientation relative to the epidermal surface (appressed to erect), and presence of papillae on trichome surface.

In this study, a member of sect. Teucrium, hitherto undescribed as a new species, was analyzed based on morphological and micromorphological features and molecular findings. The closest species of the new species were defined according to leaf morphology via morphological characters. Leaf, stem, and nutlet trichome types were obtained and compared with resembling species. Moreover, two different DNA region sequences were used to evaluate its proper phylogenetic position in the section.

The micromorphology of leaf indumentum and nutlet surface of 12 species belonging to the 6 sections of the genus Teucrium L. was studied by scanning electron microscope (SEM). Eight types of trichomes are identified including unbranched unicellular trichomes, unbranched multicellular trichomes, sessile glands, subsessile glands, stalkedmulticellular glands long clavate glandular trichomes (with 3-5 cells), trichomes with large thin-wall.

In this study, comparative morphological, anatomical and palynological studies of Stachys L. sect. Ambleia Bentham species (Lamiaceae) in Turkey are carried out on the plants collected from their type localities. These species are Stachys cydni Kotschy ex Gemici & Leblebici and S. yildirimlii M. Dinç, which are highly local endemics.

We investigated the relationship between leaf age and trichome/stomata densities in the snake tomato (Trichosanthes cucumerina L.). In a second experiment, the effects of diff erent salinity levels on trichome and stomatal densities and their micromorphology were investigated.

Trichomes, epidermal cell features, and seed coat sculpturing of 12 Lotus taxa from Egypt were studied using scanning electron microscopy. In addition, statistical analysis for the taxa under investigation was carried out. The results revealed that trichomes have high taxonomic significances between studied taxa.

Leaf indumentum and nutlet surface micromorphology of 13 taxa belonging to the Teucrium sect. Teucrium was studied with a scanning electron microscope. We observed 5 trichome types on the nutlets and 8 trichome types on the leaves. Branched trichomes were not found on the nutlets.

We studied leaflets of 18 taxa of the genus Mimosa, specifically the Dolentes-Brevipedes taxonomic complex, focusing on micromorphology, type, shape, and density of trichomes. Within the nonglandular trichomes we described 3 types of nonbranched and 2 types of branched trichomes. We also described 2 types of stalked glandular trichomes, extending the recent classifications of trichomes in Mimosa.
