Abstract:
The knowledge of deformation rezistence of sweet cherries is very
important for a good choice of means and methods of their package, storage
and transportation, for fresh consumption on national market or for export.
In this paper, the authors present the measurement results about fruits
deformation, made on 8 new sweet cherry cultivars homologated at SCDP
Iaşi in 1996 – 2006: Cetăţuia, Cătălina, Maria, Golia, Ştefan, Bucium,
Iaşirom and Tereza. These was harvested in two maturation stages (before
optimum ripening date and full maturation stage), and have registered the
fruit deformation under 500 g and 1000 g using an originally device achieved
at Fruit Growing Development Station Iaşi – Romania. This mechanical
device to measure the resistance of the fruit at deformation can be used for
different variants of weights applied over the fruit for diverse fruit-growing
species or grapes. The fruit deformation is determined by the difference
between the initial position indicated by a needle on a marked scale in
millimeters and the position resulted after the fruit deformation under
different weight. We noticed the greatest resistance to deformation was
registered by the cultivars Bucium, which was harvested before optimum
ripening date and Golia, which was harvested in full maturation stage. The
smallest resistance to deformation was registered by the cultivar Tereza
(which was harvested before optimum ripening date) and cultivar Maria
(which was harvested in the full maturity phase). The determinations
effectuated represent just a preliminary study and helped us calculate the
averages and the difference towards averages for ulterior statistical analysis
