| 红阳猕猴桃是广受欢迎的猕猴桃品种，其产业发展却被贮藏技术所限，为红阳猕猴桃果实制定
适宜的收贮运方案是提升其市场竞争力的重要手段。选用四川省蒲江县的红阳猕猴桃为试验材料，研究了
6 个不同采收期（盛花期后131、136、141、146、151、156 d）红阳猕猴桃在25（±1）℃条件下的后熟周期
（RSP，即采摘之日起至硬度低于0.5 kg/cm2），以及采收果实与后熟果实可溶性固形物（SSC）、可滴定酸
（TA）、还原性糖（RS）、维生素C、硬度、干物质等的变化规律。结果表明，红阳猕猴桃SSC 含量与RSP
呈负相关，RS 含量与RSP 呈负相关，Vc 含量与RSP 呈正相关，其中RS 与RSP 的变化趋势更为一致，推断
RS 是影响红阳猕猴桃后熟周期的主要物质。在各采收期，后熟后的果实SS 含量相较于采收果实均提高约
10 个百分点，可滴定酸降低约0.1 个百分点。而RS、Vc、干物质含量则主要受采收期影响，受鲜采果实影
响较小。因此，可依据红阳猕猴桃RS 含量预先判断果实耐贮性，从而采取不同的收贮运方案，以获得更长
的贮藏时间，并确保果实上市品质最优，从而延长销售时间、扩大销售半径。 |

| The Red Sun kiwifruit is the most popular variety of kiwifruits，while this variety is also commonly
found in markets，the fresh preservation technology limits its application in kiwifruit industrial development.
Appropriate harvest time，proper storage，and transport can contribute to good quality of kiwifruit. The Red Sun
kiwifruit varieties from Pujiang county，Sichuan province was used as experimental materials to study the effects
of harvest times（ 131，136，141，146，151，and 156 days after full bloom） on the physiological traits during the
ripening and softening periods（ RSP，that is，the date between the day of harvest and that of the flesh firmness lower
than 0.5 kg/cm2） of kiwifruits at the storage temperature of 25（±1）℃. Soluble solids content（ SSC） ，titratable
acids（ TA） ，reducing sugars（ RS） ，vitamin C（ Vc） ，flesh firmness and dry matter content in fresh fruits and
postharvest softening fruits were analyzed，respectively. The results showed that there was a negative correlation
between TA and RSP，RS was negatively correlated with RSP，Vc was positively correlated with RSP，and the
change of RS and RSP was more consistent. These results suggested that RS might be a key factor influencing RSP of
Red Sun kiwifruit.Comparison with the fresh fruit at the harvest time，the SS content of ripening and softening fruit during the storage increased by about 10%，and TA decreased by about 0.1%. RS，Vc，and dry matter content were
mainly affected by the harvest times and were less affected by fresh fruits. Therefore，the storability of kiwifruit could
be predicted based on RS at harvest time of Red Sun kiwifruit. Quality of kiwifruit cannot be improved during the
storage；thus，it is important to harvest fruits at the proper stage and size with different harvesting schemes. kiwifruit
industry is in urgent need of different harvesting schemes for preservation，shelf life extension and better maintain the
quality of fruit. |
