Tree Fruit Physiology


Highlighting the research taking place in Lee Kalcsits’ tree fruit physiology lab at WSU TFREC in Wenatchee, WA. Since joining the Department of Horticulture and the Tree Fruit Research and Extension Center at Washington State University in 2014, the focus of the lab has been understanding the complex physiological interactions between environment, genetics and horticultural management. Here, we take a whole system approach working at the agroecological, whole-plant, tissue, cellular and molecular level to address physiological questions that work to improve tree fruit productivity and tolerance to abiotic stress.

Congrats to Erica for winning a 2019 Hambelton Scholarship!

Nadia, Michelle, and I are off to Italy in June 2019 to present work on water relations in Honeycrisp apple and how rootstocks contribute to scion responses to water limitations at the International Society for Horticultural Science Symposium on irrigation of horticultural crops in Matera, Italy. Great work Nadia and Michelle!

We have published five papers in 2019 with hopefully more to come! See our publications list for more information

Welcome to Brenda Castaneda and Antoinette Avorgbedor who are starting summer positions in the lab. Brenda is a Washington Apple Education Foundation scholarship recipient returning for her second year of working on sunburn research and Antoinette is a Research and Extension Experiences for Undergraduates Intern coming from Cornell University. Welcome to both of you!

Welcome to Orlando Howe who is working in the lab while attending Wenatchee Valley College.

It has been a while since this was updated: Giverson has moved on to take a faculty position at the University of Massachusetts in December 2019, Hector started a Ph.D. at the University of Birmingham in England, Michelle has defended her MS on April 10th, and Erica successfully passed her preliminary exams. Congratulations to all!

Tia Fathia, a visiting M.S. student from Wageningen University in the Netherlands spent two months working in the lab running quantitative analysis on synchrotron-based three dimensional reconstructions of apple fruit. Thank you for all your hard work!

As a lab, we have had a busy winter season of sharing our research with the scientific community and industry. We have given more than 15 talks since the start of 2019 and will have more to come shortly!

We are off to the American Society for Horticultural Sciences annual meeting in Washington, D.C. from July 30-August 3, 2018 where Giverson, Nadia, Michelle, and Lee will be presenting research.

Lee presented two invited talks at HortConnections in Brisbane, Australia in June 2018

Welcome to summer undergraduate students: Ryan, Jack, Chloe, and Brenda from WSU, Western Washington University, Montana State University, and Wesleyan College!

Giverson presented an invited talk at the end of May to the South African fruit industry on his work with protective netting in apple.

Congratulations to Sumyya Waliullah for co-leading a publication on efficient primer design for gene expression studies in apple!

Congratulations to Michelle Reid and Raquel Gomez for receiving Hambleton Scholarships for 2018. Great Job!

Congratulations to Corina Serban who completed her M.S. in my lab in April and has accepted a position in the research and development arm of Stemilt, one of the largest tree fruit producers in the United States.

Lee presented the Robert F. Carlson Lecture at the International Fruit Tree Association Annual Meeting in Napier, New Zealand on Frbruary 26, 2018. The talk was featured in the Good Fruit Grower Article “High-Res Honeycrisp

Lee presented keynote talks at the Ontario Fruit and Vegetable Convention in Niagara Falls, Ontario on February 22, 2018 and to the Nova Scotia tree fruit industry on March 14, 2018.

Giverson led the effort on a review article published in Scientia Horticulturae titled “Effect of Protective Netting on Tree Physiology and Fruit Quality of Apple: A Review.” Great job!

The lab group was out in full force for the Washington State Tree Fruit Association Annual Show December 4-6, 2017. Corina, Giverson, Nadia, and Michelle presented in the 5-minute research flash session. This year, there were line-up to get into the room and strong industry attendance!

Corina, Giverson, Nadia, and Lee presented research at the American Society for Horticultural Sciences Annual Meeting in Waikoloa, Hawaii September 19-22, 2017.

Welcome Erica and Raquel Erica Casagrande Biasuz (PhD student) and Raquel Gomez (MS student) joined the lab in August 2017.  We are happy to have them here!
