Sugar and Acid Content and Their Genotypic Correlations of Unselected P.Persica x P.Davidiana Progenies as Affected by Hairness and Flesh Color
摘要
Abstract
Fruit sugar and acid content were determined in a group of hybrids from one family,including 22 peach and 85 nectarine genotypes, or 75 white-fleshed and 32 yellow-fleshed genotypes. Sucrose accounted for about 65% of the total sugar, and malate for about 50%of the total acid. Mean sucrose, fructose, sorbitol, total sugar, soluble solid and quinate content were significantly higher in nectarines than in peaches, while no significant difference was found in mean malate, citrate and total acid content between nectarines and peaches. Shikimate content was very low and ranged from 0.011-0.046 meq 100 g-1 FW in all genotypes studied. Flesh color did not affect sugar and acid content.Glucose and fructose had a close positive correlation (r=0.63***). Malate had positive correlations with sucrose, sorbitol, total sugar and soluble solid content. The correlation between citrate and sugars were not significant. Glucose, fructose, sorbitol and malate content seemed to be higher in late-maturing genotypes. Sucrose, total sugar and total acid content had a parabolic relationship with developmental period (from full blooming date to maturity date).关键词
