摘      要：Although it is well known that plants emit acoustic pulses under drought stress,the exact origin of the waveform of these ultrasound pulses has remained ***,we present evidence for a correlation between the characteristics of the waveform of these pulses and the dimensions of xylem conduits in *** a model that relates the resonant vibrations of a vessel to its dimension and viscoelasticity,we extract the xylem radi from the waveforms of ultrasound pulses and show that these are correlated and in good agreement with optical *** demonstrate the versatility of the method by applying it to shoots of ten different vascular plant *** particular,for Hydrangea quercifolia,we further extract vessel element lengths with our model and compare them with scanning electron *** ultrasonic,noninvasive characterization of internal conduit dimensions enables a breakthrough in speed and accuracy in plant phenotyping and stress detection.
