Variability of Old Sweet Cherries Found in Slovak Regions and Their Preservation

Abstract

Communicated by Edîte KaufmaneThe work is focused on the evaluation of variability of morphological and pomological characteristics of several old sweet cherries (Prunus avium L.)

Morphological and Pomological Characteristics of Sweet Cherry (Prunus AviumL.) GrownIn-situunder South Mediterranean Climate in Morocco

“…These values are lower than those reported in the literature for wild sweet cherries. Benková et al (2017) reported that fruit weight from Slovakian sweet cherries varied between 3.7 and 8.9 g ( Table 3). The Ukrainian cherries had fruit weight with range of 5.10-8.33 g (Hégedüs et al, 2013).…”

“…In Spanish sweet cherry cultivars, the stalk length was reported to be varied between 30.9 and 69 mm (Pérez-Sánchez et al, 2008 and for Portuguese cultivars this parameter fluctuated between 33.4 and 49 mm (Rodrigues et al, 2008). In Iranian cultivars, Khadivi-Khub (2014) reported that fruit stalk length ranged from 23.35 to 59.44 mm and in the Latvian cherries this trait varied between 34 and 60 mm with an average of 41.55 mm (Benková et al, 2017). For the machine harvesting the longer stalk is better regarding possible damage to the fruit skin as observed in the case of short stalk.…”

“…However, majority of these cultivars are self-incompatible and require the association of at least two cultivars in the commercial orchards to ensure adequate production. In the last decades, a large number of new sweet cherry cultivars with valuable pomological and agronomical characteristics was established, including same that are self-compatible and with medium chilling requirement (Benková et al, 2017;Sansavini and Lugli, 2008). The selected cultivars show distinctive agronomic characters such as low susceptibility to fruit cracking, high levels of soluble solids, early fruit maturity and great rusticity (Pérez-Sánchez et al, 2008).…”
