Abstract:
During May-June 2009, 5 early sweet cherry cultivars („Cetaţuia”,
„Cătălina”, „Rivan”, „Bigarreau Moreau” and „Bigarreau Burlat”) were
considered for the study of existing experimental plot of Fruit Growing
Research Station Iaşi- Romania, who sought modification of quality
parameters during maturation: equatorial diameter, fruit weight and soluble
solids content. For analized fruit size, determinations were made on the
equatorial diameter and fruit weight in 5 dates corresponding to different
stages of maturation between 20 and 50 days after full bloom. There have
been changes of these parameters between the first and the 5th date of
harvest, as follows: fruit weight increased in „Cetăţuia” from 0.76 g to 3.13
g and „Bigarreau Moreau” from 1.01 g to 5.63 g; equatorial diameter of
„Bigarreau Moreau” increased from 10.55 mm to 21.62 mm, and „Cetăţuia”
increased from 10.28 mm to 16.28 mm. To determine the sweet taste, was
analyzed soluble solids content in 3 different stages of maturation between 30
and 50 days after full bloom. „Cetăţuia” has increased from 10.2° Brix to
14.6° Brix and „Bigarreau Moreau” from 9.9° Brix to 13° Brix. „Catalina”
noted compared with the varieties studied, the average fruit weight and
soluble solids content with values of 6.45 g and 15.63° Brix respectively in
the last stage of maturation and „Bigarreau Moreau” was noted by
equatorial diameter which averaged 21.62 mm at the last stage of
maturation.
Catalina, Bigarreau Burlat and Bigarreau Moreau have optimum
harvest period in the range 38-42 days after full bloom, but Catalina have
better fruit quality.
