Abstract: The effects of low-temperature and temperature change on physiology characteristics of`“Hei Hu Po”plums were studied.The effects of two temperature change patterns,that is,intermittent warming form 0～-0.5℃to 18～20℃every 15 days and decreasing temperature from 10 to -0.5～0℃in 10 days on chilling injury were presented with the -0.5～0℃constant low-temperature storage as control .The results showed that serious chilling injury took place in constant low-temperature storage and enhanced the increase of cell membrane permeability and MDA content,broke up PG and PE enzyme balance and disordered pectin metabolism. Intermittent warming was manifested to be a suitable pattern.

Key words: low-temperature coerce, change-temperature, plums, physiology characteristic
