Abstract: Objective and MethodThe three kinds of storage air condition:O_2+CO_2:3;+0;;O_2+CO_2:4;+1;;O_2+CO_2:5;+2; were designed to study the effect of the different air condition on the respiration rate,ethylene production,soluble solids content,total sugar content,total acid content,hardness,pulp cell membrane permeability, etc of the 86-1 melon during storage for choosing a better storage condition. ResultThe results showed that under 3 ℃,different air condition can not control the 86-1 melon's respiration rate and reduce the ethylene production .Different air condition can keep the 86-1 melon's better flavour and total sugar,acid content. conclusionMore CO_2 content will be better for the 86-1 melon's storage, such as CO_2/O_2=2/5 was better than CO_2/O_2=0/3,whose reason should be further discussed in the future.
