Studies on the pollen morphology of Fritillaria (Liliaceae) taxa from Greece

Taxonomical relations of tribe Lilieae (Liliaceae) based on palynological issues

“…Exine ornamentation (macroreticulate, scabrate, irregular-rugulate, reticulate) and sulcus membrane ornamentation (macrogranulate and plicate-granulate) were varied in the monosulcate pollens of Fritillaria (Kosenko 1999). This variation accepted by later and present studies (Tekşen et al 2010; Hosseini 2018; Samaropoulou et al 2022). The pollen grains of Fritillaria were examined by Tekşen et al (2010) and six types of exine ornamentation had determined (reticulate, reticulate-perforate, suprareticulate, rugulate-reticulate, psilate-perforate, and perforate).…”

“…In contrast, Hu et al (2021) reported only reticulate exine surface ornamentation in the studied members of this genus. In our research, the exine ornamentation in two regions of pollen and sulcus membrane ornamentation were varied and accepted the variation of these qualitative characters in the previous palynological studies (Kosenko 1999; Tekşen et al 2010; Hosseini 2018; Samaropoulou et al 2022). It seems that reticulation and regulation had a major role in exine ornamentation of the equatorial surface and sulcus margin region of most of the taxa of genus Fritillaria based on this research and previous studies (Kosenko 1999; Tekşen et al 2010; Hu et al 2021; Samaropoulou et al 2022).…”

“…Hosseini (2018) determined three main pollen types based on exine ornamentation (reticulate, reticulate-perforate, and suprareticulate) and two sulcus membrane ornamentation (psilate and verrucate). Eight kinds of exine ornamentation (rugulate–reticulate, rugulate–perforate, psilate–perforate, perforate–reticulate, reticulate, reticulate–heterobrochate, and psilate-reticulate) and four kinds of sulcus membrane ornamentation (rugulate–granulate, psilate-granulate, gemmate, verrucate) observed in the members of Fritillaria (Samaropoulou et al 2022). In contrast, Hu et al (2021) reported only reticulate exine surface ornamentation in the studied members of this genus.…”

“…Different palynological research provided taxonomical evidence among the taxa of the tribe Lilieae (Kosenko 1999; Ozler and Pehlivan 2007; Tekşen et al 2010; Güven et al 2014; Hosseini 2018; Hu et al 2021; Samaropoulou et al 2022). In this research, we examined combined pollen micromorphological characters and ultrastructure data to complement previous palynological research and were clearer than the taxonomical relationships with palynological data.…”

Analysis of Research Status and Development Trend of Nanotoxicology of Liliaceae Medicinal Plants

“…And the formula (L-1) is as follows: 0.01 g CaCl 2 , 0.05 g MgSO 4 ·7H 2 O, 0.2 g kh 2 PO 4 , 0.221 g ammonium tartrate, 1.641 g anhydrous sodium acetate, 11.098 g glucose, 0.5 mL vitamin solution, and l mL inorganic solution [ 17 ]. Specifically, spore suspension with a concentration of 2 × 106/mL was added to 200 mL of the above medium and then placed in a constant temperature oscillation incubator to cultivate at 37 °C and 150 rpm to form mycelium pellets [ 18 ].…”
