目的 探究微孔气调包装结合保鲜剂对月季切花在低温下的保鲜效果。方法 以‘卡罗拉’月季切花为对象，分别进行孔密度20孔气调包装处理(M20)、20孔气调包装结合1-甲基环丙烯(1-MCP)处理(M20+1-MCP)、20孔气调包装结合1-MCP和SO2保鲜纸处理(M20+1-MCP+SO2)，在(4±0.3) ℃条件下贮藏并定期测定鲜切切花感官、呼吸强度、乙烯生成速率、可溶性蛋白含量、总酚含量以及抗氧化酶活性等指标。结果 与M20相比，M20+1-MCP和M20+1-MCP+SO2处理组在月季切花贮藏期间能够更好地保持感官品质，花青素、可溶性蛋白、总酚、总黄酮生化成分抑制呼吸作用和乙烯生成，减缓氧化损伤标志物丙二醛(MDA)的积累，并维持活性氧(ROS)的氧化还原平衡;在贮藏30 d时，M20+1-MCP+SO2处理的苯丙氨酸解氨酶(PAL)、几丁质酶和β-1,3-葡聚糖酶活性分别为68.87、18.64和14.87 U/g，显著高于其他处理组，并维持较高的过氧化物酶(POD)和超氧化物歧化酶(SOD)活性;瓶插寿命与MDA含量、乙烯生成速率、PPO活性呈极显著负相关(P<0.01)，POD活性与抗病性和抗逆性相关指标呈正相关。结论 微孔气调包装结合1-MCP和SO2保鲜纸复合处理主要通过维持生化成分、抑制呼吸作用、保持氧化还原平衡、提高抗病能力等途径发挥协同保鲜作用。

The work aims to explore the effect of microporous controlled atmosphere packaging combined with preservative on the preservation of cut rose flowers at low temperature. The cut rose 'Corolla' was treated with 20-hole controlled atmosphere packaging (M20), 20-hole controlled atmosphere packaging combined with 1-methylcyclopropylene (1-MCP) (M20+1-MCP) and 20-hole controlled atmosphere packaging combined with 1-MCP and SO2 plastic preservation paper (M20+1-MCP+SO2). Fresh cut flowers were stored at (4±0.3) ℃ and their sensory, respiratory intensity, ethylene production rate, soluble protein content, total phenol content and antioxidant enzyme activity were measured regularly. Compared with M20, M20+1-MCP and M20+1-MCP+SO2 treatment group could better maintain the sensory quality of cut flowers during storage. The biochemical components of anthocyanin, soluble protein, total phenol and total flavone inhibited respiration and ethylene production, and slowed down the accumulation of malondialdehyde (MDA), a marker of oxidative damage and maintained the REDOX balance of reactive oxygen species (ROS). After 30 days of storage, the activities of PAL, chitinase and β-1, 3-glucanase in M20+1-MCP+SO2 treatment group were 68.87 U/g, 18.64 U/g and 14.87 U/g, respectively, which were significantly higher than those in other treatment groups and peroxidase (POD) and superoxide dismutase (SOD) activities were maintained. Bottle life was negatively correlated with MDA content, ethylene production rate and PPO activity (P<0.01), while POD activity was positively correlated with disease resistance and stress resistance. The combination of 1-MCP and SO2 preservative paper with microporous controlled atmosphere packaging plays a synergistic role in preservation through maintaining biochemical components, inhibiting respiration, maintaining REDOX balance and improving disease resistance.
