Turkish Journal of Botany
Asphodelus aestivus Brot. (Asphodelaceae) anthers were analysed to provide a detailed understanding of the events that lead to pollen grain development, accompanied by cytochemical observations at different ontogenic stages. An anther locule of A. aestivus was bordered by 4 different layers: the tapetum, the middle layer, the endothecium, and the epidermis. At the tetrad stage, secretory tapetal cells enlarged maximally, while they showed degeneration at the young microspore stage. During the course of the degeneration, vacuolisation and reduction in the volume were conspicuous. Cytochemical analysis revealed that tapetal cells presented an intense reaction with regard to protein, insoluble polysaccharides, and …
In Vitro Germination, Protocorm Formation, And Plantlet Development Of Orchis Coriophora (Orchidaceae), A Naturally Growing Orchid Species In Turkey, Ersan Bektaş, Mustafa Cüce, Atalay Sökmen
Turkish Journal of Botany
Some species belonging to the genus Orchis Tourn. ex L. (Orchidaceae) are of great economic importance as their tubers or corms are used to produce a hot beverage called salep. Nevertheless, these plants are not cultivated but are rather collected from nature, and due to careless collection many have already been listed as endangered plants. In order to assess the possibility of in vitro propagation, an orchid, Orchis coriophora L., was selected as a model plant, and the effects of basal media and plant growth regulators on in vitro seed germination, protocorm development, and plantlet formation were studied.

Turkish Journal of Botany
Rose breeders need reliable and efficient germination protocols to exploit all viable embryos in their breeding programs. In this study, different treatment combinations were assessed to overcome the mechanical resistance of the pericarp and enhance germination of rose seeds obtained from hybridisation among hybrids roses. In the 3 treatments, 30 days of a warm temperature followed by 60 days of cold stratification and 30% sulphuric acid treatment for 10 min proved more effective in getting higher seed germination (18.54%) and seed vigour index (261.18) of the progenies. This led to lower germination (18.20 days) and imbibition (23.64) periods with respect …

Turkish Journal of Botany
This is the first report on the phenomenon of syncyte manifestation through cytomictic transmigration in Papaver somniferum L. The occurrence characteristics and cytological depictions of cytomixis in the meiotic course of gamma-irradiated population reveal the mechanism leading to the origin of the cell fusions/syncytes. The event was more frequent in meiosis I and rare in meiosis II, indicating that the process atrophies at the end of the first meiotic division. The degree of occurrence of the phenomenon virtually concurred with the increase in the treatment dose of gamma irradiation. The phenomenon also affected the qualitative composition of postmeiotic products, i.e. …

Turkish Journal of Botany
Sporobolus arabicus Boiss. is a perennial stoloniferous grass that prefers a saline or desert habitat. A natural population of Sporobolus arabicus growing in a salty area was compared with a normal nonsaline population. The salt-tolerant population showed better growth than its counterpart. Physioanatomical adaptations to saline environments in the salt-tolerant population were very specific. They included restricted toxic ion uptake, production of organic osmolytes, sclerification in roots, succulence in stem, and development of vesicular hairs on the leaves. These adaptations were not only for the excretion of toxic ions but also for the accumulation of inorganic ions in the parenchymatous …
