Abstract
The aim of this work was to study gum production in relation to water status and bark total non-structural carbohydrates (TNC). The highest production of gum occurred in December after growth and flowering. This was linked with an increased predawn plant water potential and lower bark TNC. Wound size and number increased gum production.
