Stephan Reinert, Kennedy L. Money, Greta B. G. Rockstad, Nolan C. Kane, David L. Van Tassel, Brent S. Hulke Abstract: Organic dormancy, the inability to germinate under favorable conditions, is a common problem in many crop species and their wild relatives, leading to more variable emergence, plant density, and growth rates, thus increasing costs, and […]
Zoe M. Portlas, Jonathan R. Tetlie, Deirdre Prischmann-Voldseth, Brent S. Hulke, Jarrad R. Prasifka Abstract: Wild and managed bees are needed to move sunflower (Helianthus annuus L.) pollen, both to create hybrid seed and to encourage high, consistent yields when those hybrids are subsequently grown. Among floral traits that influence bee preference, floret size may be
Qing-Ming Gao, Nolan C. Kane, Brent S. Hulke, Stephan Reinert, Cloe S. Pogoda, Silas Tittes, Jarrad R. Prasifka Abstract: Capitate glandular trichomes (CGT), one type of glandular trichomes, are most common in Asteraceae species. CGT can produce various secondary metabolites such as sesquiterpene lactones (STLs) and provide durable resistance to insect pests. In sunflower, CGT-based
Our lab is dedicated to helping college students learn about sunflower research and provide them relevant experience for their future careers. Each year we work with incoming interns to create projects for them to lead. The goal of the project is to help give interns relevant experience they can show prospective employers after they graduate.

Xuelin Fu, Lili Qi, Brent Hulke, Gerald Seiler, Chao-Chien Jan Abstract: Somatic embryogenesis in vitro provides an efficient means of plant multiplication, facilitating sunflower improvement and germplasm innovation. In the present study, using interspecific amphiploids (2n=4x=68) between cultivated sunflower and wild perennial Helianthus species as explant donors, somatic embryos were induced directly from the surface of corolla
Brent S. Hulke, Qing-Ming Gao, Michael E. Foley Abstract: One of the primary goals for the oilseed sunflower (Helianthus annuus L.) industry is to provide novel oil products for human consumption. One oil profile of particular interest is high oleic and low saturated fat, because it combines high oxidative stability of the oil with a reduction
This summer we had field locations in Courtland, MN; Glyndon, MN; Galchutt, ND; Mandan, ND; and Oakes, ND. The field locations made up about 25 acres that we completed our research on. Some of the highlights from our summer were: Testing out our new seed indexer for planting Laying out 9 miles of drip tape
