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.

Big congrats to Raquel (M.S.) and Nadia (Ph.D.) for successfully defending their thesis/dissertations this month. Both will be graduating in December!

Science in Our Valley is back for Fall 2019 and includes presentations by Raquel (October 16) and Nadia (October 23).  Wednesdays @ 4 pm at WSU-TFREC thru November 13.

Welcome to Bi Tan from the University of Tasmania who is joining the lab as a visiting scholar for the remainder of summer 2019. We are happy to have him here!

Join the Kalcsits Lab at the WSU Tree Fruit Research Field day on Wednesday, August 7, 2019. We will be highlight our work on sunburn mitigation using netting and deficit irrigation for Honeycrisp. 3:30 to 6:30 pm at the Sunrise orchard.

Nadia’s first article from her PhD research was published today in Agronomy:  “Apple Scion and Rootstock Contribute to Nutrient Uptake and Partitioning under Different Belowground Environments“.  Check it out (it’s open access). Congrats Nadia!

Raquel, Erica, and Lee attended ASHS in Las Vegas in July 2019. Raquel presented her work on exogenous ABA application in apple, Erica took home 2nd place for her poster on rootstock variation as part of the @AppleRoot2Fruit project, and Lee did a presentation about the effects of elevated summer temperatures on apple production.

The Kalcsits lab will be at the 2019 Wenatchee Mini Maker Faire this Saturday (June 1) at the Town Toyota Center.  Fun for all ages: https://wenatchee.makerfaire.com/

Congrats to Erica for winning a 2019 Hambelton Scholarship!

Nadia, Michelle, and Lee 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!

Congrats to Michelle for earning her M.S. in Horticulture in May.  Michelle will commence her new role as the Kalcsits lab manager after graduation.

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