Effect of mechanical stress on growth and anatomical structure of red pine: stem vibration

Abstract: Two studies were made of the effects of stem vibration on tree growth and anatomical structure. Vibration was used to simulate wind sway.The results of a greenhouse and an outdoor study were not consistent but did suggest that vibration might cause a short-term reduction in growth. There was no evidence that the level of vibration used caused any change in wood structure.Soil moisture affected anchorage of the tree in the soil. This, in turn, affected lateral displacement resulting from vibration and influence… Show more

“…Growth responses of plants to mechanical perturbations, known as thigmomorphogenesis (Jaffe, 1973), have been investigated in both gymnosperms and dicotyledonous angiosperms in both laboratory and field studies (e.g., Jacobs, 1954;Larson, 1965;Neel and Harris, 1971;Quirk and Freese, 1976;Ashby et al, 1979). Whether mechanical perturbations are caused by natural winds, in wind tunnels, or by various methods of shaking plants in the laboratory, most plants display a similar suite of responses: trees exposed to mild agitation tend to develop stouter and more conical stems (e.g., Grace, 1977).…”

“…Kumar et al, 2016;Stefi et al, 2016;2017a;2017b (Sharma et al, 2009), η ίδια καταπόνηση είναι σε θέση να αποικοδομήσει τις φωτοσυνθετικές χρωστικές ή να προκαλέσει καταστροφή σε πολλούς από τους χλωροπλάστες. (Quirk and Freese, 1976;Antonova and Stasova, 1993;Wodzicki, 2001 burn et al, 1972;Holopainen and Nygren, 1989;Ladanova, 1993;Pritchard et al, 1997). Σε άτομα του φυτού Phlomis fruticosa που εκτίθενται σε σχετικά υψηλά επίπεδα αέριας ρύπανσης, τα φύλλα αποκτούν χλωροπλάστες με παραμορφωμένες ή διεσταλμένες μεμβράνες και διογκωμένα grana τα οποία, τελικά, διαρρηγνύονται με αποτέλεσμα την καταστροφή των οργανιδίων (Psaras and Christodoulakis, 1987).…”
