Abstract
In this study,'Hayward'kiwifruits at appropriate harvest time and late harvest time were treated as the material to investigate the effects of 0.5 μL·L-1 of 1-methylcyclopropene (1-MCP) on post-harvest physiological biochemistry during room temperature (20℃).1-MCP treatment kiwifruits with different maturity had similar results:1-MCP inhibited the lose of kiwifruit firmness,titratable acids,vitamin c (Vc) content,fiercely inhibited ethylene production speed and respiration intensity and delayed the respiratory and ethylene activity peak.1-MCP also increased the activity of the peroxidase (POD),catalase(CAT) and superoxide dismutase (SOD).Compare to maturity Ⅰ,kiwifruit maturity Ⅱ is higher than that of maturity Ⅰ.The firmness falling of maturity Ⅱ is faster than that of maturity Ⅰ.However,the malondialdehyde (MDA) content and respiratory of kiwifruit of maturity Ⅱ are significantly higher than that of maturity Ⅰ.The degree of respiratory and ethylene production of maturity Ⅱ are ahead of the peak time.So in the same storage conditions:The degree of fruits ripening of maturity Ⅱ and senescence process was faster than that of maturity Ⅰ,significantly.Thus storage effects are not as good as the maturity Ⅰ,in brief,1-MCP treatment delayed kiwifruit maturing and softening.
