Bark Anatomy And Cell Size Variation In Quercus Faginea, Teresa Quilhó, Vicelina Sousa, Fatima Tavares, Helena Pereira
Bark Anatomy And Cell Size Variation In Quercus Faginea, Teresa Quilhó, Vicelina Sousa, Fatima Tavares, Helena Pereira
Turkish Journal of Botany
The bark structure of Quercus faginea Lam. in trees 30-60 years old grown in Portugal is described. The rhytidome consists of 3-5 sequential periderms alternating with secondary phloem. The phellem is composed of 2-5 layers of cells with thin suberised walls and narrow (1-3 seriate) tangential band of lignified thick-walled cells. The phelloderm is thin (2-3 seriate). Secondary phloem is formed by a few tangential bands of fibres alternating with bands of sieve elements and axial parenchyma. Formation of conspicuous sclereids and the dilatation growth (proliferation and enlargement of parenchyma cells) affect the bark structure. Fused phloem rays give rise …
A Contribution To Taxonomy Of Centaurea Including Psephellus (Asteraceae) Based On Anatomical And Molecular Data, Özhan Aydi̇n, Kami̇l Çoşkunçelebi̇, Mutlu Gültepe, Murat Erdem Güzel
A Contribution To Taxonomy Of Centaurea Including Psephellus (Asteraceae) Based On Anatomical And Molecular Data, Özhan Aydi̇n, Kami̇l Çoşkunçelebi̇, Mutlu Gültepe, Murat Erdem Güzel
Turkish Journal of Botany
Seven Centaurea L. s.l (Asteraceae) taxa endemic to Turkey were examined in terms of anatomical and molecular aspects to contribute to their taxonomic positions. Numerical analysis of the 13 anatomical traits showed that average row number of collenchyma and the arrangements of the vascular bundles in the stem, leaf type, and abaxial surface of leaf epidermal tissue were important to determine the investigated taxa. It was also found that the 7 investigated taxa were grouped into 2 distinct clusters based on anatomical traits and combined nrDNAITS/cpDNA data.
Fruit Anatomy Of Some Ferulago (Apiaceae) Species In Turkey, Emi̇ne Akalin Uruşak, Çağla Kizilarslan
Fruit Anatomy Of Some Ferulago (Apiaceae) Species In Turkey, Emi̇ne Akalin Uruşak, Çağla Kizilarslan
Turkish Journal of Botany
The genus Ferulago W.Koch is represented with 49 species in the world and 34 species in Turkey. In this study, comparative fruit anatomical properties based on mericarp shape in transverse section of 27 Ferulago species grown in Turkey are given. A description of Ferulago cypria H.Wolff, which was mentioned as a new record in an unpublished postdoctoral thesis, is also given. As a result of this study, we are able to identify and classify the species of this genus by using anatomical features of the fruit. In addition, an identification key has been prepared to represent the similarities and differences …
Anatomical Structures Of Vegetative And Reproductive Organs Of Senna Occidentalis (Caesalpiniaceae), Mohamed Abdel Azi̇z Ahmed Nassar, Hassan Ramadan Hassan Ramadan, Hend Mohammad Saad Ibrahim
Anatomical Structures Of Vegetative And Reproductive Organs Of Senna Occidentalis (Caesalpiniaceae), Mohamed Abdel Azi̇z Ahmed Nassar, Hassan Ramadan Hassan Ramadan, Hend Mohammad Saad Ibrahim
Turkish Journal of Botany
The current investigation is concerned with the histological features of Senna occidentalis (L.) Link (coffee senna plant). The anatomical structure of different vegetative and reproductive organs was investigated weekly or fortnightly, according to the investigated organ, throughout the growing season. Organs studied included the main root, main stem (represented by shoot apex, apical, and median internodes), different foliage leaves developed on the main stem and on lateral shoots (including lamina and petiole), epidermal peel and trichomes, flower buds, fruits, and seeds. Histological features of various organs of the coffee senna plant were analysed microscopically and photomicrographed. Moreover, ultrastructural features of …
Phytotoxic Effects Of Herbicide Attribut And Surfactant Biopower On The Root, Stem, And Leaf Anatomy Of Triticum Aestivum Pehlivan, Gülden Yilmaz, Feruzan Dane
Phytotoxic Effects Of Herbicide Attribut And Surfactant Biopower On The Root, Stem, And Leaf Anatomy Of Triticum Aestivum Pehlivan, Gülden Yilmaz, Feruzan Dane
Turkish Journal of Botany
This study was performed in order to determine toxic effects of different doses of Attribut (propoxycarbazone-sodium) used in wheat fields and BioPower (sodium alkyl ether sulphate) surfactant added to Attribut on Triticum aestivum L. Pehlivan. The doses used in the study were 0.42 mM Attribut, 0.82 mM Attribut, and 1.68 mM Attribut with or without 0.25% BioPower. Laboratory studies showed that the effective concentration value corresponded to the farmer dose, 0.42 mM Attribut. Applications were done by seed treatment. The effects of each of the doses applied to wheat plants were monitored in terms of anatomical parameters. Attribut doses of …
