PetIole ANATOMY OF SOME LAMIACEAE TAXA
Abstract:
In this
study, anatomical structures of the petiole of 7 taxa viz.,
Glechoma hederacea L., Origanum vulgare L., Scutellaria
salviifolia Bentham, Ajuga reptans L., Prunella vulgaris L., Lamium
purpureum L. var. purpureum, Salvia verbenaca L., Salvia viridis L.,
Salvia virgata Jacq.,
belonging to the Lamicaceae family were examined and compared. In all
the studied taxa, some differences were found in the petiole shape,
arrangement and number of vascular bundles, hair types and the presence
of collenchyma. G. hederaceae, S. virgata and O. vulgare consist of a
total of 3 vascular bundles, with a big bundle in the middle of the
petiole and a single small vascular bundle in each corner. P. vulgaris
has 5 vascular bundles. S. verbenaca has a total of 11 vascular bundles,
with a big bundle positioned in the middle. L. purpureum L. var,
purpureum consists of 4 vascular bundles. S. salviifolia has 3 vascular
bundles. A. reptans has a total of 9 vascular bundles, with 1 big bundle
in the middle.
S. viridis
consists of 7 vascular bundles. Petiole has glandular and eglandular
hairs. Eglandular hairs consist of capitate hairs, whereas peltate hairs
are only found in S. salviifolia 1Department of Biology, Faculty of Art and Science, Ordu University, Ordu, Turkey 2Department of Biology, Faculty of Art and Science, ²Dumlupınar University, Kütahya, Turkey 3Department of Biology, Faculty of Art and Science, ³Ondokuz Mayıs University, Samsun, Turkey |
