Analysis of the Influencing Factors of Flesh Firmness in Loquat Germplasm Resources

In order to investigate the influencing factors on flesh firmness of loquat germplasm resources,the flesh dregs degree,flesh texture,flesh juice,fruit weight,flesh thickness,total soluble solids of juice,peel thickness,density of floss on fruit surface,length of floss on fruit surface,origin region,flesh color,peel color and flesh firmness of loquat germplasm resources in Loquat Resource Nurseries of Fuzhou National Fruit Gene-pool were studied and analyzed.The results indicated that the flesh dregs degree,flesh texture,flesh juice,flesh color and density of floss on fruit surface and fruit maturity stage had great influence on flesh firmness,and the flesh firmness of loquat germplasm resources with dreggy flesh dregs degree,tight flesh texture,few flesh juice,yellow and orange yellow flesh color,sparse density of floss on fruit surface and early fruit maturity stage were relatively higher.The fruit weight,flesh thickness,pericarp thickness,origin region,total soluble solids of juice,length of floss on fruit surface and peel color had no significant internal relations with the flesh firmness.
