| Abstract:
During 1998-1999, one hundred sour cherry genotypes were evaluated regarding their fruit cracking susceptibility. The observations were carried out in the field (1998 were the most favourable meteorological conditions to promote the natural fruit cracking in the last ten years) and in the laboratory, where this phenomenon was artificially induced by imersion of cherries in distilled water. In the controlled conditions, 65 varieties were investigated two years and 35 one year, counting the damaged fruits after 6 and 24 hours. Twenty varieties were checked, one year, at two moments of ripening phenophase, a week before the fruit’s full maturity and at optimum harvesting time. The percentage of cracking fruits, varying in the large scale, from 0 to 100%, demonstrated high varietal susceptibility differences. The fruits of ‘Louis Philippe’, ‘Gorsemkric’, ‘Milwavre’, ‘Ludwig Fruhe’, ‘Richmorency’, ‘Olivet’, ‘Montearly’, proved to be the most resistant to cracking, while ‘Royal Duke’, ‘Dobraya’, ‘Bizighesti’, ‘Kelleris 16’, ‘Turcesti’, ‘Transparente d’Espagne’, ‘NY 6935’, ‘Granatnaya’ cvs. were highly susceptible to this undesirable phenomenon. | |
