The exploitation of micromorphological parameters for identification in the section / Mentha Využitie mikromorfologických parametrov pri identifikácii v sekcii Mentha
Abstract The identification of species in the genus Mentha is especially difficult because of the ease of hybridization, favoured by gynodioecy, which is further complicated by polymorphism, cultivation, polyploidy and vegetative propagation. This all explains the genicpopulation and microevolutionary background for variability of mints. In this work we studied the usage of micromorphological and phytochemical parameters in identification and characterization of selected Mentha species. On abaxial surface of leaves of 20 Mentha populations we determined the size and the number of peltate glandular trichomes. The essential oil was analysed by GC MS. We identified and characterized populations of M. × piperita, M. spicata, M. spicata subsp. condensata, M. spicata var. crispa, M. spicata var. citrata, M. × gentilis, M. aquatic, M. arvensis amd M. longifolia. The size and the number of peltate glandular trichomes contribute to characterisation of some Mentha species (especially in M. longifolia and M. × piperita). Slovak Abstract Identifikacia druhov v rode Mentha L. je obzvlašť naročna. Je to sposobene ľahkym križenim podporenym gynodioeciou, ktora je ďalej skomplikovana polymorfizmom, pestovanim, polyploiditou a vegetativnym rozmnožovanim, čo vysvetľuje genetickopopulačne a mikroevolučne pozadie premenlivosti v rode Mentha. V tejto praci sme študovali využitie mikromorfologickych a fytochemickych parametrov pri identifikacii a charakterizacii vybranych druhov rodu Mentha. Na spodnej pokožke listov 20 populacii Mentha sme stanovili veľkosť a počet „žliazok typu Lamiaceae“. Silicu sme analyzovali pomocou GC MS. Identifikovali a charakterizovali sme populacie druhov M. × piperita, M. spicata, M. spicata subsp. condensata, M. spicata var. crispa, M. spicata var. citrata, M. × gentilis, M. aquatic, M. arvensis a M. longifolia. Sledovanie veľkosti a počtu „žliazok typu Lamiaceae prispievaju k charakterizacii niektorych druhov Mentha (najma M. longifolia a M. × piperita).
Illicium verum Hook. f. and Illicium anisatum L.: Anatomical Characters and their Value for Differentiation
In the last years intoxications after consumption of Illicium verum Hook. f. have been reported due to adulterations with I. anisatum L.. Many efforts have already been made to develop a simple method which would enable the detection of I. anisatum in powdered samples of I. verum. Since many controversial facts concerning the value of anatomic characters for differentiation have been published 13 botanically vouchered samples were re-examined by means of light microscopy, fluorescence microscopy, SEM, and confocal laser scanning microscopy. All anatomical details show a great variability even between the follicles of a certain aggregate. This is also true for the cuticular striation which has been proposed in literature as reliable character. Special attention was paid to the structure of the aleurone grains of the endosperm and the shape of the calcium oxalate crystals in the testa. In contrast to previous assumptions these characters do not allow a certain differentiation either. However, the presence of hexagonal crystals can serve as indicator for samples of I. anisatum. At present a reliable proof of purity of powdered samples of I. verum seems to be possible by chemical analytical methods only.
