Recent research has made significant strides in understanding the propagation and management of both invasive and native plant species. A new study has focused on the reproductive potential of glossy buckthorn (Rhamnus frangula), an invasive shrub that poses ecological challenges in various regions. This research offers crucial insights into seed yield, seed size, and germination rates, providing data that can inform management and regulatory decisions aimed at mitigating the environmental impact of this species.
The findings clarify how different cultivars of glossy buckthorn contribute to its seed production and spread. This understanding is vital for developing strategies to manage its growth and reduce its negative effects on local ecosystems. These insights are particularly important as many regions seek to implement bans on invasive species while allowing exceptions for low-fecundity cultivars.
The second study examined propagation strategies for northern bayberry (Morella pensylvanica), a native shrub appreciated for its landscape and ecological benefits. Researchers discovered that a technique known as “retipping” for micropropagated plants significantly increased liner yield. This method offers a practical approach to enhancing nursery production efficiency, enabling growers to reliably supply this desirable species for restoration and ornamental purposes.
According to Dr. Brand, a Professor of Horticulture and Plant Breeding at the University of Connecticut, the research on glossy buckthorn aimed to support the nursery industry in confirming the low fecundity levels of specific cultivars. He noted that publishing fecundity data in peer-reviewed journals is essential for obtaining sterile cultivar exemptions in state bans on invasive plant species. The research was conducted by graduate student Jackie Edgett, who has since joined the staff at the Arnold Arboretum in Boston, MA.
The full articles detailing these studies can be accessed through the American Society for Horticultural Science (ASHS) electronic journal, HortTechnology, at the following links: https://doi.org/10.21273/HORTTECH05632-25 and https://doi.org/10.21273/HORTTECH05625-25. Established in 1903, ASHS is a globally recognized professional society that promotes scientific research and education in horticulture. With thousands of members worldwide, ASHS represents a diverse community of horticultural scientists, educators, students, and industry professionals focused on improving practices in breeding, propagation, production, and management of horticultural plants.
Together, these studies underscore the importance of scientific research in supporting both the management of invasive plant species and the sustainable production of beneficial native plants. As environmental pressures continue to challenge ecosystems, such research becomes increasingly valuable for strategic resource management and conservation efforts.
