UDC 575.11:582.683.2 CYTOGENETICAL INVESTIGATION OF CROATIAN STENOENDEMIC SPECIES FIBIGIA TRIQUETRA (Brassicaceae)

چکیده
This paper concerns the cytogenetic investigation of the Croatian endem ic species Fibigia triquetra (DC.) Boiss. (Brassicaceae). The number of chro mosomes in all investigated cells from three populations of Fibigia triquetra was 2n=2x=!6. Chromosomes were small and ranged from submetacentrics to acrocentrics. One chromosome pair had a relatively small satellite. Although meiosis was not completely regular, irregularities were not very frequent. Low pollen germination rate was probably due to these irregularities. As the species is perennial, weakness of seed germination seems not to be important for its survival.

Glucosinolate Profile of Croatian Stenoendemic Plant Fibigia triquetra (DC.) Boiss. ex Prantl
As part of our ongoing investigation of the stenoendemic plants belonging to the Brassicaceae family, we report on the chemistry of Fibigia triquetra (DC.) Boiss. ex Prantl for the first time. Different plant parts (flower, leaf, stem, and seed) of F. triquetra were characterized and quantified for glucosinolates (GLs) according to the ISO 9167-1 EU official method based on the HPLC analysis of...
متن کاملPhysiological and biochemical responses of Fibigia triquetra (DC.) Boiss. to osmotic stress
Water defi cit in the soil leads to osmotic stress in plants. The type of stress affects plant water relations, osmolyte accumulation and oxidative stress balance. The present study aimed to investigate the effects of osmotic stress on the Croatian perennial species Fibigia triquetra (DC.) Boiss, adapted to a hot and dry habitat. Plants grown in culture conditions were subjected to isoosmotic c...

Vesubia jugorum (Simon, 1881) (Araneae: Lycosidae) is a large-sized wolf spider that occurs in alpine rocky areas above 2,000 m altitude. The species is stenoendemic, with a limited number of populations documented in the literature from the Maritime Alps (Italy, France). Due to the climate change, the current observed extent of occurrence (EEO 4,412 km ) and the area of occupancy (AOO 835 km )...

To achieve sustainable development as well as the conservation of natural ecosystems and their biodiversity, it is necessary to study ecological foctors and their impacts on plant species diversity. The Khorramabad-Andimeshk highway was selected in the current study to investigate the diversity of the family Brassicaceae. The length of this highway is 100 km and its height ranged from 420 to 17...
