Abstract
The‘Nanguo’pears were packed with plastic bags(0.02mm)after being fumigated for 20h with 0.75μL/L 1-MCP(1-Methylcyclopropene)or with plastic bags(0.04mm)after filled with 2% CO2 and cold storage(0±1℃)for 5months,then stored at ambient temperature(18 ℃±3 ℃)for investigation.The browning index,mitochondria protein content,MDA content and ATP content were determined in order to study the effect of 1-MCP and CO2 on pear fruits energy metabolism characteristics during the shelf life after cold storage.The results show that:(1)Both 1-MCP and CO2treatments can delayed the core browning index and browning degree differently,and the 1-MCP was better than CO2;(2)Both 1-MCP and CO2 treatments helps to retarded the increase of MDA and membrane permeability,holds the integrity of membrane;(3)1-MCP treatment helps to increase the content of mitochondria protein during the prophase of shelf life.1-MCP treatment can also remain high ATP content and energy charge level in postphase of shelf life.And filled with CO2 treatment can keep a high level of ATP content and energy charge in prophase of shelf life.It is suggested that both 1-MCP and filled with CO2 can adjusted the postharvest senescence process through effect the energy metabolism characteristics.In this study,the effectiveness of 1-MCP treatment is better than filled with CO2 on inhibited the core browning and kept the integrity of membrane.
