Fruit quality and biochemical characteristics of new early ripening apricots of Turkey

Abstract

In this study, the important fruit quality characteristics of 11 early ripening and promising apricot hybrids and reference cultivars recently developed in Turkey were analyzed. A large variation was observed between the genotypes in terms of fruit size (fruit weight ranged from 34.28 to 72.53 g). The total soluble solids which is one of the significant fruit quality parameters for the table apricots, was found between 10.07 and 18.27% and fruit flesh/kernel rate was between 9.6 and 18.42. Epicatechin, rutin, catechin, chlorogenic acid, epigallocatechin gallate and β-carotene were found to be the highest bioactive compounds. A large variation was also determined among the genotypes in this regard. ABP-4-23 and ABP-7-12 apricot genotypes were rich with respect to catechin, chlorogenic acid, epicatechin, rutin and β-carotene. The highest catachin and epicatechin contents were obtained in respectively). In terms of β-carotene ABP-2-24 and ABP-1-18 presented the highest values (127.45 and 119.54 mg/kg, respectively). Fruit weight was found highly and positively correlated with kernel weight and total soluble solids (r = 0.65 and r = 0.61, respectively). Fruit weight was also found to be moderately correlated with rutin, quercetin, and β-carotene, while corrrelations was negative for rutin and β-carotene. Total acidity was moderately correlated with catechin, epigallocatechin gallate and β-carotene in positive way.

Characterization of new late-spring-frost-tolerant apricot hybrids: physical and biochemical fruit quality attributes, volatile aroma compounds

“…Clarification of interactions among fruit characteristics via correlation analyzes brings useful practical knowledge for consumer food preferences and also for breeding studies aiming those preferences. Most of the correlations on physical and biochemical fruit quality traits presented in this current study were in accordance together with some opposite results and additional correlations reported by the previous studies (CALİSKAN et al, 2012;KARAAT & SERÇE, 2019;ÇUHACI et al, 2021). The variation among the reported results would probably be caused from the genotypic and environmental conditions.…”
