摘要
[目的]研究12个芒果品种的4个抗氧化酶活性,分析其相关性并做出综合评价.[方法]测定12个不同成熟期芒果品种的抗氧化酶活性,采用相关、通径及隶属函数分析方法,研究不同成熟期芒果品种抗氧化酶活性差异.[结果]超氧化物歧化酶(SOD)、过氧化物酶(POD)和过氧化氢酶(CAT)与果实成熟天数间存在极显著差异,CAT对果实成熟期起到直接作用,直接通径系数为0.619,而SOD、POD可能通过CAT对果实成熟期起到间接作用,间接通径系数分别为-0.599 8、-0.588 7.12个芒果品种的隶属函数评价结果为桂热芒780-17、印度芒901号、桂热芒10号、桂热芒282号、桂热芒78-1号、桂热芒264号、斯里兰卡芒811号、桂热芒30号、桂热芒10-2号、泰国芒14号、桂热芒23号、红花本地芒.[结论]该研究可为探讨酶活与果实发育的相关性奠定基础.
Abstract
[Objective] To study four antioxidase activites of 12 mango varieties,analyze the relationship and make a comprehensive evaluation.[Method] The antioxidant enzymes activities of 12 maturity mango cultivates were investigated.Then the rule was studied by using correlation, path and subordinate function analysis.[Result] There were extremely significant correlations between SOD,CPOD,CAT,and fruit maturing, CAT had greater direct impact on fruit maturing, and the direct path coefficient was 0.619.SOD and POD had indirect impact on fruit maturing by CAT, indirect coefficients were-0.599 8,-0.588 7.The subordinate function analysis of 12 mango cultivars was as follows: Guire mango 780-17> India mango 901> Guire mango 10> Guire mango 282> Guire mango 78-1> Guire mango 264>Sri Lanka mango 811>Guire mango 30> Guire mango 10-2>Thailand mango 14> Guire mango 23>Honghua mango.[Conclusion] The study provided basis for studying the correlation between enzyme activity and fruit development.
