近日,由华南植物园段学武、蒋跃明等完成的“盐酸聚六亚甲基胍在防治柑桔酸腐病上的应用及其保鲜剂”获得国家发明专利授权(专利号:ZL 2010105422783)。柑桔是世界第一大水果,属非呼吸跃变型果实,但采后呼吸代谢旺盛导致营养与风味品质迅速下降。例如沙糖桔皮薄汁多,采后病害发生严重,更不耐贮藏。沙糖桔贮藏期间发生的主要病害有酸腐病、青绿霉病、黑腐病和蒂腐病。目前,控制沙糖桔果实病害的最有效的途径是低温贮藏结合化学杀菌剂处理,所用的杀菌剂有多菌灵、甲基托布津、抑霉唑、双胍盐(百可得)
Recently, the South China Botanical Garden Duan Xuewu, Jiang Yueming and other “ polyhexamethylene guanidine hydrochloride citric acid in the prevention and control of the application of preservatives” won the national invention patent (Patent No .: ZL 2010105422783). Citrus is the world’s largest fruit, is a non-climacteric fruit, but post-harvest respiratory metabolism led to the rapid decline in nutritional and flavor quality. For example, Shatang orange juice thin juicy, postharvest disease serious, more impatient storage. Shatangjian the main diseases occurred during storage were acid rot, green mold, black rot and rot rot. At present, the most effective way to control Saxifraga crispum is low temperature storage combined with chemical disinfectant. The bactericides used are carbendazim, thiophanate methyl, imazalil, biguanide (100)
