Architecture of the Internodal Xylem of Tomato (Solanum Lycopersicum) With Reference to Longitudinal and Lateral Transfer

Abstract: The anatomical organization of the internodal tomato xylem was studied with the goal to relate xylem architecture, longitudinal flow, and lateral solute displacement in the stem. On account of a vessel member inventory, obtained by maceration, two vessel types were reconstructed distinct in diameter, morphology, and location. Type I: wide vessels (diam 50–160 μm), with a relatively constant diameter and low horizontal perforation rims, the widest (in the main areas) often extending over more than one internode… Show more

“…This opens the route to new studies about any existing physical relationship between L and R in a single plant. Note that although observed values of L and R were reported in literature 25,44,45 , those were obtained only across different species by either destructive microscopy or X-ray microtomography.…”

“…The elasticity of macroscopic segments of plant stems can be measured via various mechanical loading techniques 23,24 , which are invasive. Existing techniques to measure xylem dimensions, such as paint-injection, X-ray micro-CT, and optical and electron microscopy [25][26][27][28] , are also destructive and time-consuming.Here we present a physical model that links the dimensions and (visco-)elasticity of xylem vessels, to measured ultrasound pulses. We compare information about the radius, length, and viscoelasticity of xylem vessels obtained by analysing ultrasound pulses, to that gained by independent destructive techniques on Hydrangea quercifolia.…”

“…The bubble formation excites axial standing waves in the sap (water), whose resonance frequencies depend on the longitudinal speed of sound in the pipe veff, and the xylem vessel element length L (Methods). We model the xylem vessel as a resonant cylindrical pipe containing a series network of vessel elements of length L, which are bounded by scalariform perforation plates (3,28) (see Fig. 2A).…”
