Descripción
Pinus canariensis is adapted to volcanism, as it inhabits the Canary island archipelago since 13.5 Million years. It is able to survive volcanism disturbances due to its resprouting ability. We simulated volcanic damages along two consecutive years in 8 year old P. canariensis trees growing outdoors in the University fields. Trees were divided in three groups and assigned to the following treatments: i) C: Control trees ii) D: Defoliated trees (complete defoliation + bud removal) iii) DD: Defoliated+Wounded trees (same as defoliated+ a wound in the stem). Growth was continuously measured every 15 minutes with linear variable displacement transducers placed at the stem base of all trees with a precision of 1 micrometer. Maximum daily stem schrinkage (MDS) values as well as cumulative radial growth were determined. Results showed an immediate decrease in MDS after complete defoliation, but oscillations in stem diameter remained appreciable, showing patterns of stem swelling and shrinking similar to those measured in control trees, and independent from variations in air temperature. First year D and DW trees ceased their radial growth after treatment imposition in July and recovered it by November. However, growth was not recovered by the end of the year after the second defoliation.
