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 ▲]

Les alcaloïdes mineurs du Strychnos gossweileri

In previous papers, we related the isolation and identification of several indole alkaloids from the root-bark of Strychnos gossweileri: alstonine, a well known anhydronium base, dolichantoside a new indol-glucoalkaloid and diploceline, a new quaternary alkaloid. From a second batch of the same species, we isolated, besides the previously isolated compounds, three new alkaloids. The structure elucidation and the stereochemistry of these alkaloids ( isodolichantoside, strychnofluorine and 16-epi-diploceline) are now discussed. [less ▲]
