Research and Development in Seed Science and Technologies at the Oregon State University Seed Laboratory

blower-calibrationResearch in seed science and technologies has been one of the strengths of OSU Seed Laboratory. The constant contact of the lab with thousands of customers facing seed testing and management issues, gives the lab a unique capacity to generate highly applicable research to solve pressing problems. Some research is conducted with own funds, while other larger projects are funded with grants or contract or fees. Currently, the research and development at the OSU Seed Lab focuses on five areas:

Through publication, the results of research are shared with the greater scientific, testing and production community.

Mechanization of Seed Separations

Mechanization and automation of seed testing and seed separations

blower-calibrationThe purpose of this area of research is to incorporate or introduce new technologies to solve problems and develop methods that can better respond to the current and the future industry needs. The ultimate goal in this area is to simplify procedures, increase efficiency and assure quality. 

Completed Projects

Interests and opportunities for new projects

Seed Viability and Performance

Validations and enhancement of seed viability, vigor, grow-outs and other seed performances

The objective of the research in this area is to speed up germination, assure germination uniformity and to verify plant types through grow-out testing and performance by several means: breaking dormancy efficiently, improving scarification methods, chemical-physical treatments and additives and by accelerating plant development for effective species identification.

Completed Projects

Interests and opportunities for new projects

Genetic and Trait Testing

Development of tests to determine genetic and other quality traits

Research projects in this area focuses on traits that define the value of seeds in the market particularly for seeds produced or used in Oregon.

Imaging and Information Systems

Development of digital and electronic information systems in seeds

We have one of the most advanced databases and programs that contain information for test results of approximately 30,000 tests every year. This information is a treasure to generate knowledge on purity, germination, specific contaminants, and other quality attibutes by crops, years, companies, warehouse, etc. This information can be used to generate research to understand and solve problems, to assist customers on seed management programs and to plan innovations for the lab or customers.

Customer-Driven Projects

Research projects for seed companies, research and extension educators

This area focuses on any seed related research in response to specific needs of others including research, extension, industry customers that are working on seed related projects. The clients bring treated samples (products of chemical treatments, production practices, time of harvest, etc) and the lab completes the seed evaluations. The following are some examples that were completed in the last few years:

Completed Projects

Future Projects

Future projects in this area is open to the needs of customers in seed related areas such as: moisture content, purity, germination, vigor, seed identification, ploidy, TZ, seed search in soil or compost or feed pellets, etc. If you have a need or idea, bring it up to the lab and we may be able to assist in designing the study, performing experiments, and analyzing data.
