Cavitation Events in Thuja occidentalis L.? : Utrasonic Acoustic Emissions from the Sapwood Can Be Measured.
Ultrasonic acoustic emissions (AE) in the frequency range of 0.1 to 1 megahertz appear to originate in the sapwood of Thuja occidentalis L. The AE are vibrations of an impulsive nature. The vibrations can be transduced to a voltage waveform and amplified. The vibrations of each AE event begin at a large amplitude which decays over 20 to 100 microseconds. Strong circumstantial evidence indicates...
متن کاملThe Effects of Climate on Radial Growth of Disjunct Northern White Cedar (Thuja occidentalis L.) in Virginia
Understanding the geographic range and growth of species is essential for effective land management in a landscape affected by anthropogenic activity and climate change. Climate change is expected to alter the distribution and growth of many tree species in eastern North America, including northern white cedar (Thuja occidentalis L.). This research examined the effects of climate on radial grow...
متن کاملAntimicrobial Activity of the Essential Oil of Thuja Orientalis L
The essential oil from seed coats of Thuja orientalis L. (Family cupressaceae) obtained in an yield of 1% has been studied for its antimicrobial activity against 6 bacteria and 5 fungi using filter paper disc agar diffusion technique. The oil has shown good to moderate activity of the oil against all six test bacteria. The activity of the oil against S. typhi has been found remarkable at 1:1000...
متن کاملMechanisms of drought response in Thuja occidentalis L. II. Post-conditioning water stress and stress relief.
We examined the extent of osmotic adjustment and the changes in relative water content (RWC) and transpiration rate (i.e., relative stomatal function) that occur in water-deficit-conditioned 6-year-old Thuja occidentalis L. (eastern white cedar) trees in response to a severe drought. Trees conditioned by successive cycles of mild or moderate nonlethal water stress (conditioning) and nonconditio...
متن کاملMechanisms of drought response in Thuja occidentalis L. I. Water stress conditioning and osmotic adjustment.
We investigated the extent of osmotic adjustment and changes in transpiration rate that occur in response to repeated cycles of water deficit stress in 6-year-old Thuja occidentalis L. (eastern white cedar) trees. Groups of trees were water-stress conditioned by repeated exposure to predetermined thresholds of nonlethal water stress by withholding water until the predawn water potential fell to...
