“…Similar results were obtained by Şenel et al (2007) in the V. bithynicum and V. wiedemannianum species. In contrast to the current study and Senel et al (2007), Hilooğlu and Sözen (2017) concluded that there was an increase in germination percentages by significant numbers with GA3 treatments in the species V. alyssifolium in comparison to the control. Ganatsas et al (2019) reported 32.0%, 26.7%, and 40.0% germinations from seeds of different sizes in the species V. dingleri without any treatments.…”

“…While the implementation of constant dark completely inhibited germination, the photoperiodic treatments of 12 / 12 and 8 / 16 light / dark were detected to be effective light regimes for V. yurtkuranianum seed germination. Unlike the current study, Senel et al (2007) found that to establish the seed germination protocols of V. bithynicum and V. wiedemannianum, a dark environment was the best treatment. Isık et al (2017) acquired the best germination results for the V. dudleyanum, V. natolicum, V. serratifolium, V. suworowianum, V. suworowianum, and V. orientale species by applying the 8-h light/16-h dark periodic regime.…”

“…Particularly, its hairless and bright green leaves increase the potential use of this species as an ornamental plant. Among the species of the genus Verbascum (Huber-Morath 1978), it is similar to the V. bugilifolium species in leaf structure and peduncles (Kaynak et al 2006) and to the V. weidemannianum species with amaranth purple corolla in corolla structure (Senel et al 2007), in spite of its difference in corolla color (blue). Unlike the V. wiedemannianum, it has hairless leaves and violet flowers, and it grows fewer pedicels per peduncle.…”

“…In agreement with the current study, they achieved the best germination rate for the V. wiedemannianum species with the 16-h light/8-h dark photoperiodic regime, which falls into the secondary group in the current study. Senel et al (2007) found that the effect of treatments of light, dark, and photoperiod can vary based on the species, and they should be established separately and meticulously for each species. Chanyenga et al (2012), in contrast, reported that seeds of certain species can equally germinate both in light and dark conditions.…”

Verbascum yurtkuranianum is a narrow endemic species occurring in a single location, the northern Bursa province (Turkey). It is an endangered and potentially ornamental plant. No conducted study on its life and biology, production, and aesthetic features is available. This study aimed to reveal its vegetative properties, seed characteristics, methods and requirements for seed germination, germination speed, and potential ornamental value so it can be conserved ex situ and produced. Verbascum yurtkuranianum has potential value as an ornamental plant regarding its aesthetic features as a flower. This study revealed that the total number of individuals in the species is 788. Without any treatment, 70.7% germination rate is achieved if the seeds are stored at 4 °C. The optimum germination temperature was from 15 to 20 °C (77.3% and 78.7%, respectively), and the photoperiod regulation for seed germination was 12/12 or 8/16 (light/dark) hours (74.7% and 76.0%, respectively). The most effective treatment to promote germination rate was found by implementation of 60 min ultrasonic waves (94.3%) or application of 120 min vacuum (95.3%). Germination occurred between 8 and 10 days. A parcel of ex situ conservation was constituted with the seedlings obtained from the germination studies.

Threshold temperatures for seed germination in nine species ofVerbascum(Scrophulariaceae)

et al. 2015

View full text Add to dashboard Cite

Light and fluctuating temperatures are two important factors triggering seed germination. The aim of this work was to: (1) elucidate the effect of temperature, light regime and storage time on seed germination in nine taxa ofVerbascumspp., collected from different habitats in the Mediterranean area; and (2) estimate threshold temperatures for seed germination. For all taxa, germination assays were performed at constant and fluctuating temperatures, both in continuous darkness (D) and in alternating light/dark (L/D; 12 h photoperiod). Final germinated proportions (FGPs), base (Tb), optimal (To) and cut-off (Tc) temperatures were derived. At constant temperatures, seed germination was strongly suppressed under the D regime. In L/D, the effect of storage time was very small and the highest FGPs were observed from 15 to 30°C (40–100%), depending on the species.Tbranged from below 7 to above 10°C and it appeared to be constant within each seed lot.ToandTcshowed some within-lot variability and were higher for fast-germinating seeds in each lot. Considering fluctuating temperatures, germination appeared to be quicker and more complete than at constant temperatures. The germination ofVerbascumspp. is favoured in L/D and fluctuating temperatures, which explains their pioneer character when positioned near the soil surface and under a low vegetation canopy.V. arcturusandV. pinnatifidumwere shown to be less favoured by L and fluctuating temperatures, which might explain their ability to germinate in rocky areas or sandy dunes, even when they are not directly exposed to the light.

Regeneration Ecology of the Rare Plant Species Verbascum dingleri: Implications for Species Conservation

et al. 2019

Verbascum dingleri Mattf and Stef. is a Greek endemic plant species belonging to the family of Scrophulariaceae that only occurs in northeastern Greece, east of the city of Kavala. Knowledge of species distribution, habitat requirements, reproduction, ecology, and population characteristics is limited in the literature. In this study, habitat characteristics, population counts, fruit and seed diversity, and germination were studied for the first time. The results indicate that the species geographical distribution is very restricted, lying in the Mediterranean floristic zone at a low altitude (100–200 m asl) and on very shallow soils. The habitat of this species is characterized by the Csa climate type, with a mean annual precipitation of 602 mm and a mean annual temperature of 14.6 °C. The species occurs in the area lying between the geographical coordinates 40°58′16.59″ N, 24°27′54.93 E, and 41°05′7.2″ N, 24° 47′17.2″ E. The species thrives in degraded shrub communities, dominated by the shrub species Paliurus spina-cristi Mill., Olea europea L. ssp. europaea, and Quercus coccifera L. Only a very small number of individuals were found (less than 200) at a density considered too small for long-term persistence of the species. The fruits of the species contained a high number (mean value 58.2) of minute seeds. The seeds exhibited high germination (up to 80.0% in laboratory and up to 30% in ambient conditions). We conclude that in situ and ex situ species conservation and habitat restoration are feasible through the introduction of seedlings produced from seeds collected from local populations.
