本文对Tommy Atkins或Keitt种芒果的各种采后防腐处理进行了评价。在68.95千帕的压力下,用0—8％的氯化钙溶液压力渗透2分钟,难以防治在13℃下贮藏17天,随后在24℃下软熟期间的芒果炭疽病和蒂腐病。在生物防治试验中,枯草杆菌的B_3菌株可抑制离体的盘长孢状刺盘孢和蒂腐色二孢生长,但在贮藏期间芒果用枯草杆菌的悬浮液处理不能防止炭疽病和蒂腐病的发展。经53℃的热水处理3分钟的芒果,用剂量为250或750戈瑞的钴60辐射2小时,可减少炭疽病和蒂腐病的发生。辐射增进果实的内分解,尤其是经750戈瑞剂量辐射的芒果。
This article evaluates various post-harvest preservative treatments for Tommy Atkins or Keitt mango. Pressure impregnation with a 0-8% calcium chloride solution for 2 minutes at a pressure of 68.95 kPa makes it difficult to control mango anthracnose and pediculosis during storage at 13 ° C for 17 days followed by soft cooking at 24 ° C. Bacillus subtilis strain B_3 inhibited in vitro growth of Spodoptera pleuromorph and Sporotrichum tricuspidata in biological control trials, but treatment of B. subtilis suspension with mango during storage did not prevent anthrax and decay The development of the disease. Mango treated with hot water at 53 ° C for 3 minutes and irradiated with cobalt 60 at a dose of 250 or 750 Gy for 2 hours reduced the incidence of anthracnose and pediculosis. Radiation enhances the internal breakdown of the fruit, especially the mango irradiated at 750 Gy.
