Fruit School 2015
Thank you to everyone who participated in this year’s fruit school!
Each participant received handouts that included a thumb-drive preloaded with the abstracts and presentation files. However, Dr. Matt Whiting’s presentations were inadvertently left out. You will find a download link next to the listing for his talks below.
WSU Extension presented a 2-day workshop at multiple locations simultaneously that focused on the newest scientific information on tree fruit physiology. Session topic areas included:
Session I: Pome Fruit Physiology 101
Objective: Understand basic physiology of apple and pear including growth and development, floral initiation and the role of hormones
- Plant Growth & Development – Matt Whiting, WSU download abstract & slides
- Endogenous Hormones – Duane Greene, Univ. of Massachusetts
- Floral Initiation – Matt Whiting, WSU download abstract & slides
Session II: The Dynamic Nature of Nutrient & Water Relations and Importance of Roots in Modern Orchard Systems
Objective: Understand roots and their relationship with canopy growth and productivity.
- Roots, A General Primer – Lee Kalcsits, WSU
- Nutrient Uptake and Distribution – Massimo Tagliavini, Bolzano
- Irrigation and Nutrient Management – Denise Nielsen, AAFC Summerland
