Abstract：In order to determine the harvesting standard of'Harlikar'apples with different storage and transportation life,the starch index,firmness,soluble solids,respiration rate,ethylene release rate,volatile aroma components and other indexes of'Harlikar'apples harvested at different harvest dates were measured in this study.At the same time,GC-MS was used to analyze the changes in volatile aroma components.The results showed that the firmness of apples harvested in the stage I(165 days after blooming)was as high as 7.50 kg/cm2,but the content of soluble solids and volatile aroma was low,and it was sensitive to low temperature,freezing injury began to appear after storaged at-0.5℃for 120 days.'Harlikar'apples harvested in the stage Ⅲ(195 days after blooming)had high soluble solids content(15.0%)and flavor,but the firmness decreased to 6.8 kg/cm2.After stored for 120 days,the firmness decreased to 5.6 kg/cm2 and the flesh began to mealiness and browning.'Harlikar'apples harvested in the stage Ⅲwas suitable for fresh sale or short-term storage.'Harlikar'apples harvested in the stage Ⅱ(180 days after blooming)were suitable for long-term storage,the firmness was 7.40 kg/cm2,soluble solids content was 15.40%,titratable acids was 0.18%,starch index was 7.83,and storage life was about 180-240 d.
