Gypsophila davisii üzerinde anatomik, palinolojik, morfolojik, karyolojik ve ekolojik araştırmalar

Öz

Muğla'ya endemik bir tür olan Gypsophila davisii Barkoudah, anatomik, morfolojik, ekolojik ve palinolojik açıdan bir bütün olarak ilk kez incelenmiştir. Bilinenin aksine incelenen örneklerin kök ve gövdelerinde hiçbir druz kristaline rastlanmamıştır. Tohumlar armut şeklinde olup yüzeyinde parlak düz tüberküller vardır. Polen taneleri, çok porlu, küremsi, granül-mikroekinat-mikroperforattır. G. davisii'nin 30 somatik kromozomu vardır (2n = 30). Örnekler morfolojik açıdan Türkiye Florası’ndaki betim ile karşılaştırılmıştır.

Anatomical, palynological, morphological, karyological, and ecological investigations on Gypsophila davisii

Öz

Gypsophila davisii Barkoudah, an endemic species from Muğla (Turkey), was investigated for the first time as a whole in terms anatomy, morphology, ecology, karyology, and palynology. No druse crystals were observed in stems and roots of examined specimens in contrast to the known. Seeds are pyriform with shiny, smooth grooves on the surface. The pollen grains are polyporate, spheroidal, granulate-microechinate-microperforate. G. davisii has 30 somatic chromosomes (2n=30). The samples are compared morphologically with the description given in Flora of Turkey.
