‘Baili' and‘Jiefangzhong' were used as matierials to study relationship between cell wall metabolism and fruit texture of loquat.The results show the polygalacturonase(PG,EC 3.1.1.15), pectinesterase(PE,EC 3.1.1.11) and Cellulase(Cx,EC 3.2.1.4) act1 ivities of two cultivars were generally a tendency towards increase during fruit development.The activities of the above three enzymes during the later fruit developing stage were significantly higher than those from the earlier fruit growth stage(p<0.01),and pe...
