Peer-reviewed publications build on more than three decades of research and highlight student contributions

FRANKFORT, Ky. — A short shelf life, vulnerability to disease, and the difficulty of establishing young trees have long constrained pawpaw’s commercial potential. Five new studies by ÍøÆØ³Ô¹Ï researchers address those barriers and deepen the scientific understanding of North America’s largest native fruit.

FloweringFour of the newly published studies examine critical aspects of pawpaw production, including flowering, disease management, postharvest storage, and seedling establishment. A fifth evaluates the potential of luffa, bitter melon, and yard-long beans as specialty crops for Kentucky growers.

The research builds on ÍøÆØ³Ô¹Ï’s nationally recognized role in pawpaw conservation, cultivation, and commercialization. The University began formal pawpaw research in 1990 and has maintained a U.S. Department of Agriculture satellite repository for pawpaw since 1994. More than 2,000 trees representing plant material collected from 17 states grow across 12 acres at the Harold R. Benson Research and Demonstration Farm in Frankfort.

The five peer-reviewed articles appear in Acta Horticulturae, the scientific and technical proceedings of the International Society for Horticultural Science. Six current or former students in ÍøÆØ³Ô¹Ï’s Master of Science in Environmental Studies program contributed as primary or co-authors: Anju Chaudhary, Manisha Hamal, Sijan Pandit, Kshitij Shahi, Subas Thapa Magar, and Jacob Vincent.

Flyer“These studies show how ÍøÆØ³Ô¹Ï transforms decades of specialized knowledge into practical information that growers can use,â€� Dr. Kirk W. Pomper, professor of horticulture, said. “Just as importantly, our students are contributing directly to peer-reviewed research, gaining hands-on experience as scientists, and helping address real production challenges that affect agriculture in Kentucky and beyond.â€�

Together, the pawpaw studies provide information that could help growers improve production and support the continued development of the fruit as a commercial crop. The specialty vegetable study offers Kentucky growers research-based guidance for assessing additional production and marketing opportunities.

The International Society for Horticultural Science promotes horticultural research and education and facilitates cooperation among researchers, educators, and industry professionals around the world.

Work by ÍøÆØ³Ô¹Ï’s Pawpaw and Horticulture Research Group advances the University’s mission as an 1890 land-grant institution by developing science-based information and new agricultural opportunities for farmers, students, and communities across the Commonwealth and beyond.
