Correlations between sugar and acid content and peach growth

Water scarcity conditions affect peach fruit size and polyphenol contents more severely than other fruit quality traits

“…This means that the decrease in dilution by water is a major consequence of drought treatment. Our data showed that drought induced an increase in glucose and fructose concentrations along with a decrease in fruit growth, which is in accordance with results of Génard et al Indeed, those authors reported a negative correlation between concentration of reducing sugars and fruit growth rate during the third stage of peach fruit development.…”

A novel gene, screened by cDNA-AFLP approach, contributes to lowering the acidity of fruit in apple

“…grape [23], blackcurrant [24], and peach [25], has also revealed that malate is the major organic acid utilized during ripening. These findings support the hypothesis that malate is also used to sustain fruit expansion [26]. Therefore, it could be inferred that fruit acidity is negatively regulated by Mal-DDNA, i.e.…”

Phenotypic diversity and relationships of fruit quality traits in peach and nectarine [Prunus persica (L.) Batsch] breeding progenies

“…The quality parameters may not be independent of each other, and therefore, relationships among them should be studied to improve the choice of production objectives. Previous studies carried out in peach (Byrne et al 1991;Génard et al 1994;Esti et al 1997;Génard et al 1999) have found correlations among some pomological traits related to the fruit quality.…”
