Description
Sap flow analysis was developed in France in the 1980s and can be used very effectively to measure the rate of transpiration through tree trunks in woody species such as apple. This method is also used in forestry in Québec, including by researchers at Université Laval.
The hypothesis was that it should be possible to measure sap flow in apple trees and correlate it with soil water conditions and the weather. This is the first time this method has been used for apples in Québec.
Objective(s)
- Assess the potential of analyzing sap flow in apples as an additional tool for determining irrigation recommendations for apples based on the physical properties of the soil and local weather conditions
From 2017 to 2018
Project duration
Fruit production
Activity areas
Optimal water management
Service
This study of how apple tree sap flow relates to soil moisture and weather conditions is a first in Québec.
