Abstract
Effects of Lasiodiplodia theobromae on reactive oxygen species (ROS) production-scavenging system during L. theobromae-induced pericarp browning and disease development of harvested “Fuyan” longans were investigated. Compared with control longans, L. theobromae-inoculated longans exhibited higher pericarp browning index and fruit disease index, higher pericarp O2â generation rate and MDA content. Moreover, L. theobromae infection also resulted in lower contents of pericarp AsA and GSH, lower levels of pericarp DPPH radical scavenging ability and reducing power. Additionally, L. theobromae infection decreased the activities of pericarp SOD, CAT and APX from day 2 to day 5. These findings suggested that L. theobromae-induced pericarp browning and disease development of harvested longans might be due to reduction of ROS scavenging ability and increase in ROS production, which might stimulate membrane lipid peroxidation, disrupt cellular membrane structure, and cause the loss of cellular compartmentalization and disease resistance, in turn, resulting in pericarp browning and disease development.
