Fruit And Seed Macro- And Micromorphologies Of The Genus Matthiola (Brassicaceae) In Turkey And Their Taxonomic Value, Ayla Kaya, Murat Ünal, Abdurrahman Sefali, Esra Marti̇n
Turkish Journal of Botany
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. According to our findings, all characters of fruit and seeds are extremely …

Seed Structure And Its Taxonomic Implications For Genus Thlaspi Sensu Lato Sectionsnomisma, Thlaspi, And Pterotropis (Brassicaceae), Mehmet Cengi̇z Karai̇smai̇loğlu, Osman Erol
Turkish Journal of Botany
We studied morphological and anatomical characteristics of seeds of 22 taxa in the sections Nomisma, Thlaspi, and Pterotropis of Thlaspi sensu lato from Turkey and the significance of these characters in a taxonomical context. The results show that the taxa differ from each other in terms of seed shape and color. The seed size ranges from 1.25 mm to 2.99 mm in length and from 0.66 mm to 2.16 mm in width, Thlaspi rosulare and T. tatianae having the largest and T. annuum having the smallest seeds. The seed surface ornamentation is classified into nine types: reticulate-areolate, scalariform, reticulate, reticulate-foveate, …

Micromorphological Studies On The Genus Lotus L. (Fabaceae: Loteae) From Egypt, Momen Zareh, Ahmed Faried, Nashwa Farghaly
Micromorphological Studies On The Genus Lotus L. (Fabaceae: Loteae) From Egypt, Momen Zareh, Ahmed Faried, Nashwa Farghaly
Turkish Journal of Botany
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. Anticlinal and periclinal cell walls and epidermal cell shape for the stem, leaf, and calyx for each taxon were examined. Seed coat sculpturing exhibited 4 main different surface patterns categories: rugose, reticulate, sulcate, and verrucate. These features can serve as good diagnostic characters at the species level of the genus Lotus.

A Taxonomic Study Of The Silene Sections Behenantha And Dichotomae (Caryophyllaceae) In Turkey Based On The Micromorphology Of Their Seed And Pollen, Mehmet Kuh, Kemal Yildiz, Ersi̇n Mi̇nareci̇
Turkish Journal of Botany
The seed and pollen grain micromorphologies of 10 taxa of the Silene sections Behenantha and Dichotomae (Caryophyllaceae) were analyzed in this study. Although the seeds of the analyzed taxa were generally reniform, S. tenuiflora and S. koycegizensis from the section Behenantha were clearly distinct from other taxa, while subspecies of S. dichotoma and S. euxina in the section Dichotomae showed differences. Pollen grains are periporate and spheroidal and ornamentation is generally spinulate-microperforate in all taxa. However, ornamentation is spinulate in S. euxina and semireticulate in S. koycegizensis. While the exine structure is generally tectate, it is semitectate in S. koycegizensis. …

Morphology Of The Seed Coat Of Oxalis Spp. From Buenos Aires Province (Argentina), Sonia Rosenfeldt, Beatriz Gloria Galati
Morphology Of The Seed Coat Of Oxalis Spp. From Buenos Aires Province (Argentina), Sonia Rosenfeldt, Beatriz Gloria Galati
Turkish Journal of Botany
The aim of the present study is to provide detailed morphological descriptions of the seed coat in 10 species of Oxalis from Buenos Aires Province, Argentina, using light microscopy and scanning electron microscopy. The seed is ovate and brown, and its surface is smooth. Oxalis has a mechanism of spermobolia by which a part of the seed coat is detached by the rupture of cells, leaving exposed a layer of opened cells, generally with oxalate crystals. This new coat surface has different characteristics in the species studied in this work. Three types are recognized, mostly on the basis of anatomical …

Fruit And Seed Morphology Of The Fumaria L. Species (Papaveraceae) Of Iran, Fatemeh Ebrahimzadeh Araii, Maryam Keshavarzi, Masoud Sheidaii, Parinaz Ghadam
Turkish Journal of Botany
The macro and micro fruit and seed morphology and surface ornamentations of 21 populations of 6 Fumaria L. species were investigated using stereomicroscope and scanning electron microscopy. These data are shown to support data from the general morphology. The results indicate that the fruit and seed characters of the genus Fumaria are valuable for taxonomic applications and are useful for classification. F. officinalis show a different shape in their fruit. The close relationships are observed for F. parviflora and F. vaillantii. F. indica, as a hybrid between F. asepala and F. parviflora, shows intermediate micro-morphological features.

Turkish Journal of Botany
The fruit and seed morphologies of 6 species previously placed in the genus Malcolmia W.T.Aiton were examined with stereomicroscopy and scanning electron microscopy (SEM) in order to determine the significance of fruit and seed features as taxonomic characters. This study presents macro- and micromorphological characters, including fruit and seed shape, size, colour, fruiting pedicel size, fruit hair and density, seed coat pattern, epidermal cell shape, and anticlinal and periclinal cell walls. The results showed that the morphological characteristics of the fruit and seed could be used as criteria to distinguish genera and tribes. The investigated features of specimens indicated that …

Pollen And Seed Morphology Of Velezia L. (Caryophyllaceae) Genus In Turkey, İlham Eröz Poyraz, Ebru Ataşlar
Turkish Journal of Botany
In this study, pollen and seed morphology of Velezia L. (Caryophyllaceae) species in Turkey were investigated by light and scanning electron microscopy. The genus is represented by 5 species in Turkey: V. tunicoides P.H.Davis, V. hispida Boiss., V. quadridentata Sibth. & Sm., V. pseudorigida Hub.-Mor. and V. rigida L. Endemism ratio of the genus is 60%, which shows that Turkey is the gene center for this genus. The pollen grains of Velezia species are radially symmetrical and isopolar, oblate-spheroidal, operculate, and polypantoporate, pores with conical spinules on operculum. Pollen ornamentation, pore numbers, exine thickness, pore diameter, operculum ornamentation, and spinule …

Pollen And Seed Morphology Of The Genus Hesperis L. (Brassicaceae) In Turkey, Münevver Pinar, Ahmet Duran, Tali̇p Çeter, G. Ni̇lhan Tuğ
Turkish Journal of Botany
Pollen and seed morphology were examined in 35 specimens representing 25 Turkish species of the taxonomically complex genus Hesperis L. by light and scanning electron microscopes. Three main types and 2 subtypes were recognized based on the seed coat surface, pollen shape, and exine sculpturing. The seed coat ornamentation of Type I was ocellate, and pollen shape was oblate-spheroidal. While Type II was represented by reticulate seed coat and prolate-spheroidal pollen shape, Type III had tuberculate seed coat. This study revealed that both palynological and seed morphological characters are of significant importance in the taxonomy of the genus.
