I.P.P.S. Eastern Region, North America
Supports Research Through Horticultural Research Institute

The Eastern Region, North America also supports research through its gifts to the Horticultural Research Institute (HRI). This nonprofit organization is devoted to the support and conduct of research necessary for the advancement of the nursery/landscape industry. At present, the Eastern Region, North America has fulfilled eight funds with HRI named for individuals held in high esteem by the I.P.P.S. Eastern Region, North America for their service and dedication to this Society.

For every $15,000 donated by the Eastern Region, North America to HRI, a fund is named in honor or memory of an esteemed member. The honorees (whose bios can be seen by clicking on their names) are:

Each year, grants are awarded by HRI to fund research projects in plant propagation to further the ideals of the I.P.P.S. Eastern Region, North America.

Eastern Region Supports Research to
Develop Stress Tolerant Landscape Plants

The IPPS Eastern Region Fund with the Horticultural Research Institute (HRI) provided a 2010 research grant in the amount of $4,250.00 to the Landscape Plant Development Center in Mound, Minnesota. Dr. Harold Pellett is the principal investigator of the project to be funded: "Development of Stress Tolerant Landscape Plants for all Regions of North America." The Landscape Plant Development Center is a national, non-profit research institute that develops durable plants that are tolerant of environmental and biological stresses.

Dr. Pellett explains the project....

Significance:
Although there are some other research efforts devoted to developing new landscape plants, our breeding effort stresses developing plants that are more resistant to environmental and biological stresses. Our research effort is the only coordinated approach that involves cooperation of different institutions to utilize the combined resources of those institutions and that takes advantage of different climatic conditions found in different regions to select plants that are better adapted to environmental stresses. Landscape plants provide physical, economic, and social benefits to people, yet there are many challenges to creating healthy and sustainable urban landscapes. While some plants can tolerate these conditions, there is a limited palate of plant materials from which to choose. Also at present there is tremendous interest by the general public in using native plant materials in their landscapes. Native species are well adapted to our general climatic conditions and are perceived by the public as having greater stress tolerances. However, many of our native shrub species are quite rangy in growth and often do not have as desirable a growth form as do many of the exotic species that are commonly used.
There is good potential for breeding and selecting superior plants of native species. We are expanding our effort to develop superior cultivars of native species of woody plants. We are emphasizing development of cultivars of species that are tolerant of shade, poorly drained soils, or soils with poor fertility. Although native plant species are well adapted to the climatic conditions of their native region, growing conditions in urban areas are far from natural, and factors like soil compaction, drought, low fertility, and high soil pH can lead to poor planting success and premature plant death of some native species. Many native species are quite specific in their site requirements and therefore are not very tolerant of the soil and environmental conditions found in man modified environments in developed areas. Thus to develop a broad palette of landscape plants that are more tolerant of biological and environmental stresses, the landscape plant development center is working with both native and non-native plant species. Concern about invasive non-native plant species continues to increase and governmental units are becoming increasingly active in considering banning production and sales of species that are invasive. Availability of sterile cultivars of those non-native species that are well adapted to environmental conditions found in developed sites will enable the industry to continue to grow and distribute those species for landscape use.

Objectives: The objective of this research is to use traditional breeding techniques and biotechnology approaches to develop aesthetically superior landscape plants that are tolerant of biological and environmental stresses for all regions of the country. Another objective of our research is development of sterile cultivars of non-native plant species that are well adapted to climatic and soil conditions of man modified environments found in developed areas but that have a tendency to become invasive in native ecosystems.

Outcomes and Economic return: Our research project results in superior new plants, which directly benefits the bottom line of the members of the nursery industry. New plants are the lifeblood of the industry. They create excitement for gardeners leading to increased sales of nursery products. Our breeding emphasizes the development of stress tolerant plants coupled with superior aesthetic qualities and sterile plants of species that have invasive tendencies. Those traits are especially valuable to the industry in the current market. An increased palate of well adapted plants makes it possible for green industry professionals to provide a better product for the end consumer. Results of our research efforts are very beneficial to all phases of the nursery industry.


2010 RESEARCH GRANT

Due to the transition phase between the funding of a Research Grant by the IPPS Eastern Region, North America directly and the funding of grants by the newly founded IPPS Eastern Region Foundation, Research Grant Proposals will not be accepted in 2010. Watch this site for future research grant opportunities.
