Understanding seed characteristics, germination, and seedling establishment patterns is essential for formulating effective management strategies to control invasive species. Glossy buckthorn ...(Frangula alnus) is a shrub or small tree from Eurasia that has become invasive in North America, and which has negative impacts on plant communities and ecosystems. In this study, we analyzed the germination response of glossy buckthorn seeds to different temperatures (12, 14, 16, 18, 20, 24, and 28 °C), various stratification lengths (4 to 20 weeks), and scarification conditions to measure the impact on breaking seed dormancy, and the effect of light in triggering germination. Analysis using distinct time-to-event approaches, including the Kaplan–Meier estimator and Cox proportional hazard model, was employed to interpret germination data. Glossy buckthorn seeds exhibited physiological dormancy and required cold stratification to germinate. At 12 °C, only 14% of the seeds could germinate. At warmer temperatures, germination rates increased, reaching a peak of 70% at 20 °C. At 24 °C and 28 °C, germination declined, and seeds were probably induced into secondary dormancy. Scarified seeds had a higher probability of germination than non-scarified ones, even at the lowest temperatures. Darkness had a negative impact on germination at all tested temperatures. This study significantly advances our understanding of how temperature, light, stratification, and scarification impact glossy buckthorn seeds, elucidating the species’ seasonal germination patterns in North America. The results emphasize that glossy buckthorn utilizes seed banks as a primary strategy for invading and establishing in new habitats. The ungerminated seeds form persistent seed banks, ensuring F. alnus’ survival and bolstering its chances of successful establishment and invasion. As climate change drives temperature increases, it may affect seeds in the soil, altering stratification periods and consequently shifting the timing of germination.
The purpose of the study was to determine the suitability of wastes from herbal industry for biogas production. Wastes of lemon balm (Melissa officinalis L.) and alder buckthorn (Frangula alnus ...Mill.) were used for biomethane potential test (BMP). The following properties were determined in the tested material: total solids content (TS), volatile solids content (VS), total Kjeldahl nitrogen content (TKN), total organic carbon content (TOC), total phosphorus content (P) and total potassium content (K). Biogas yield was monitored on the basis of the liquid displacement method. The examined wastes differed in terms of basic properties affecting the biogas production. Alder buckthorn contained more VS, TKN and TOC, while lemon balm had a narrower C/N ratio and higher P and K content. Tested wastes were also different in terms of biogas production kinetics. In case of lemon balm, the highest production was observed at the beginning of the experiment, while the anaerobic digestion of alder buckthorn waste was only noticeable in the third week of the experiment. This delay caused higher cumulative methane yield of lemon balm waste by about 60% than that of alder buckthorn. Despite those differences, wastes from both plants were suitable for biogas production, mainly as co-substrates. Co-digestion resolves problem of utilization of such wastes and decreases the demand for energy crops such as maize which should be used as fodder and food in the first place. In addition, clear differences in the kinetics of anaerobic digestion may cause that simultaneous use of both tested wastes will ensure continuous biogas production at a relatively high level.
BACKGROUND: “VITALPLANT” medicinal plant
mixture, aimed at body weight regulation and metabolism
enhancement was formulated in order to be incorporated
as an ingredient in functional food ...formulations on the
basis of known biological activity of the alder buckthorn
bark, peppermint, caraway and parsley. METHODOLOGY:
The body weight-lowering potential, hypolipidemic effects
and antioxidant activity of “Vitalplant” mixture were
examined on five groups of male Wistar rats on different
food regimes for 14 weeks. RESULTS: “Vitalplant” mixture
supplementation caused an increase in food intake, but
induced a decrease in body weight gain. The lipid status
and atherogenic index (AI) were significantly improved in
“Vitalplant” mixture supplemented hyperlipidemic (HF)
groups in comparison to HF group. “Vitalplant” mixture
was able to influence the activity of antioxidant enzymes
and to protect erythrocytes of the rats fed the HF diet from
oxidative damage, which was indicated by significantly
lower malondialdehyde (MDA) levels in “Vitalplant”- HF
groups in comparison to the HF group. CONCLUSION: “Vitalplant” mixture seemed to be beneficial for the
reduction of body weight and improvement of antioxidant
status of the erythrocytes, and its antihyperlipidemic
property was highly active for enhancing the profile of
plasma lipids in rats.
A quantitative analysis method for total anthracene derivatives in Frangula Syrup preparation that used direct spectrophotometry at analytical wavelength 524 nm was developed. The technology for ...producing Frangula Syrup from a decoction of alder buckthorn (
Frangula alnus
Mill.) bark at a raw material:extractant ratio of 1:3 was elaborated. The error of a single analysis of total anthracene derivatives in Frangula Syrup was ± 4.17% at the 95% confidence level. The content of total anthracene derivatives in Frangula Syrup varied from 0.30 ± 0.02 to 0.37 ± 0.02%.
The widely used name Frangula alnus (syn. Rhamnus frangula) has in recent years been threatened by F. dodonei, an allegedly older name said to be published in a rare work by Pietro Arduino. However, ...from the context of Arduino's paper it is clear that "F. dodonei" is not a binomial; it just happens to look like one, and has no nomenclatural status.
