Test on Near Freezing Temperature Storage of Yuluxiang Pear

The objective of the study is to elucidate the effects of near freezing temperatures on storage quality. The Yuluxiang pears are used to investigate the effects of-1.5 ℃ and 0 ℃ treatments on fruit quality after storage. Comparison of the effects of-1.5 ℃ and 0 ℃ treatments indicated that-1.5 ℃ treatment decreased decay rate,reduced core browning, postponed respiratory climacteric,delayed the decline of firmness and titratable acidity,slowed increasing of the relative electrical conductivity and malondiadehyde(MDA). But there is no significant difference between the two treatments in soluble solids(SSC). The studies show that near freezing temperature can improve quality,and delay senescence.
