摘  要：
为探讨6-苄基腺嘌呤(6-BA)对鲜莲子活性氧代谢及能量水平的影响,以清水浸泡为对照,在25±1℃条件下,用20 mg·L-16-BA对莲蓬太空莲36号进行处理,研究其贮藏期间感官品质变化及呼吸作用强度,并分析莲子活性氧水平,抗氧化酶活性,丙二醛(MDA)、三磷酸腺苷(ATP)、二磷酸腺苷(ADP)、磷酸腺苷(AMP)含量以及能荷水平的变化。结果表明,与对照相比,6-BA处理可有效抑制莲蓬呼吸作用、莲子活性氧水平上升及MDA的积累,且保持抗氧化酶活性的同时,维持了莲子较高的能荷水平,从而延缓了鲜莲蓬和莲子品质的下降,使其贮藏期延长了3~4 d。综上,6-BA处理对减缓莲蓬和莲子采后衰老具有显著效果,本研究为鲜莲蓬和莲子采后保鲜提供了理论及技术支持。

摘  要：
To investigate the effect of 6-benzylaminopurine( 6-BA) on reactive oxygen metabolism and energy status of fresh lotus seeds,the lotus pods"space lotus numbered 36"were treated with 20 mg·L-1 of 6-BA at 25 ± 1℃,and the lotus pods treated with distilled water were used as control. The effect of 6-BA treatment on quality and respiration intensity of lotus pods and seeds,the level of reactive oxygen species,antioxidant enzymes activities,contents of malondialdehyde( MDA),adenosine triphosphate( ATP),adenosine diphosphateadenosine( ADP) and adenosine monophosphate( AMP),as well as the energy status of lotus seeds during storage were studied. The results indicated that when compared with control,treatment of 6-BA significantly inhibited the respiration intensity of lotus pods. In addition,it also treatment delayed the accumulation of reactive oxygen species and MDA content,while improved the activities of antioxidant enzymes,and maintained high energy status of lotus seeds,thereby delayed the worsen of lotus pods and the seeds quality decreasing,which extended the storage time for 3-4 days. Therefore,6-BA treatment possess high capacity of retarding the senescence of lotus pods and seeds,which provided theoretical and technical support for postharvest of lotus pods and seeds.
