Research and Teaching
at the
University of Minnesota

We conduct innovative research basic and applied focusing on the environmental physiology or flowering and photosynthesis.  Special emphasis is placed on researching the basis for high temperature inhibition of flowering and photosynthesis to accelerate development of high temperature tolerant crops worldwide.

Applied research efforts focus on developing production protocols to produce crops at non-traditional times, production protocols for new ornamental crops (especially high temperature and/or drought tolerant crops such as cacti and succulents), developing innovative ways to market food crops, identifying vegetable crops and protocols for northern production with reduced inputs, reducing production inputs of all crops.

Our research program is driven by the needs of the industry with an eye on meeting the needs of a changing world with more limited resources.  Some of that work includes developing orhganic production protocols for ornamental and food crops.

Information on current research can be found under the "Research" subheading above. This includes our past research publications.    Past publications on commcerial crop production can be found under the "Commercial Info" subheading above.

Cacti:
Photoperiod, irradiance, and temperature affect Echinopsis 'Rose Quartz' flowering (Erwin, O'Connell and Altman, 2016)

Succulents:
Benzyladenine foliar sprays increase offsets in Sempervivum and Echeveria (Carey, Whipker, McCall and Buhler, 2008)
