“…Thus, it is logical to suggest that the type of stresses supported by the cell wall might play an important role in vesicles formation, perhaps by affecting calcium displacement. 'GRANNY SMITH" APPLES 163 Compressed cells show a deformation in the direction of the applied load, verifying the model postulated by Chen et al (1986);Dal Fabro et al (1980); Holt and Schoorl (1977 b); Nilsson et al (1958);Pitt (1982); Segerlind and Dal Fabro (1978); where cells under slow loads (compression) undergo a change in shape, becoming smaller in the direction of the applied load as they begin to fill the intercellular spaces. The cell walls would behave elastically giving back part of the energy applied, b=?…”

“…It is highly efficient for a small, growing plant, because it provides rigidity and strength with a remarkably small investment of material [31,43]. In root crops or unripe fruit, the mass of cell-wall polymers may be less than 2 % of the total mass of the turgid tissue.…”

-Plant cell walls provide form and mechanical strength to the living plant, but the relationship between their complex architecture and their remarkable ability to withstand external stress is not well understood. Primary cell walls are adapted to withstand tensile stresses while secondary cell walls also need to withstand compressive stresses. Therefore, while primary cell walls can with advantage be flexible and elastic, secondary cell walls must be rigid to avoid buckling under compressive loads. In addition, primary cell walls must be capable of growth and are subjected to cell separation forces at the cell corners. To understand how these stresses are resisted by cell walls, it will be necessary to find out how the walls deform internally under load, and how rigid are specific constituents of each type of cell wall. The most promising spectroscopic techniques for this purpose are solid-state nuclear magnetic resonance (NMR), and Fourier-transform infrared (FTIR) and Raman microscopy. By NMR relaxation experiments, it is possible to probe thermal motion in each cell-wall component. Novel adaptations of FTIR and Raman spectroscopy promise to allow mechanical stress and strain upon specific polymers to be examined in situ within the cell wall. © 2000 Éditions scientifiques et médicales Elsevier SAS Cellulose / growth / mobility / pectin CP, cross-polarisation / FT, Fourier-transform / IR, infrared / MAS, magic-angle spinning / NMR, nuclear magnetic resonance / T 2 , spin-spin relaxation time constant

“…The method relies on the fact that the rigidity or elasticity (Young's modulus) of a plant tissue is a function of the turgor pressure of the tissue. The turgordependence of the elastic modules (E) is roughly given by the equation (18):…”

The mechanism of the rapid inhibition of hypocotyl elongation by blue lght was investigated in cucumber (Cucumis sativus L.) and sunflower (Helnthus annus L.) where dV/dt is the relative rate of volume increase, L is the cell hydraulic conductance, 0 is the cell wall extensibility, a is the solute reflection coefficient, Air is the difference in osmotic potential between the inside and the outside of the cell, and Y is the yield threshold for wall expansion. In principle, light may act on any of these parameters to decrease the growth rate.As described at length in the preceding report (4), measurements of turgor pressure and half-time for changes in growth rate provide
