Water flow in the plant continuum is thought to be controlled by the leaf, xylem and the root radial conductances. Leaf conductance is widely recognized as the master control in the system as it can act as a switch in the water flow, even under high transpiration demand. The control of the stomatal aperture by the plant has been the object of numerous research projects since decades and different models have been developed to study stomatal regulation. The plant hormone abscisic acid (ABA) produced in the leaves acts as an endogenous signal triggering stomatal closure, but is also thought to act as a long distance signal that is produced by roots experiencing water deficit. However, the relative contributions of leaf-supplied ABA, root-supplied ABA and xylem water potential in the regulation of water flow remains a matter of controversy. Using a novel functional structural plant model (PlaNet-Maize-ABA), we report here a first attempt to explicitly simulate ABA production, degradation, translocation in all plant organs and their effect on the transpiration flow.

The objective of this study was to assess the effect of temperature (5-25°C) on the ‘in vitro’ and ‘in vivo’ growth rates of Penicillium italicum and to determine the combined effect of temperature and relative humidity (45 to 100%) on lesion size of this pathogenic fungus on Valencia late oranges, either alone or in combination with the antagonistic yeast strain Z1 of Pichia guilliermondii Wickerham. Statistical analysis showed a significant effect of temperature on the ‘in vitro’ and ‘in vivo’ radial growth of P. italicum with the maximum growth observed at temperature of 25°C. In both cases, no growth was observed at a temperature of 35°C. These factors had a significant effect on P. italicum lesion size when it was applied alone on Valencia late oranges and insignificant when yeast strain Z1 was applied 24 h before P. italicum inoculation. Our results confirm previous ‘in vitro’ findings that aw has a greater influence than temperature on P. italicum growth and highlight that the strain Z1 showed high antagonistic potential against this pathogen over a range of temperature-relative humidity regimes favouring P. italicum development.

The paper analyses the ability of thin-film tactile sensors in providing information during static compression tests of ‘Jonagold’ apples (Malus pumila) of different ripeness stages. Such sensors are able to measure the contact surface and the interfacial pressure distribution during compression of fruits, this latter being characterised by suitable mathematical parameters. Results of compression tests between two flat steel plates are presented. The differentiated evolution of the pressure distribution according to the fruit maturity is pointed out. Ability of the sensor in evaluating the firmness is also discussed. [less ▲]

We study the impact of the stomatal opening variations on the transpiration of the entire canopy in protected crops cultivation. Three effects contribute to a reduction of this impact: a damping effect due to the boundary layer adhering to the leaf, a thermal negative feedback effect linked to the energy balance and a hydric negative feedback effect linked to the water balance. Summing up these effects gives a coupling factor between the relative stomatal conductance changes and the relative transpiration rate modifications. Detailed expression of the coupling factor is established in the frame of a dynamic greenhouse climatic model (GGDM) and its value is calculated for typical days of a temperate climate. The results show that large stomatal conductances are poorly effective in the control of the canopy transpiration (coupling factor =.1 ). Significant values of the coupling factor are only obtained for very small stomatal conductances (gST < 10-3 ) . These values are independant of the climatic conditions but are strongly affected by the development stage of the vegetation. [less ▲]
