    Effects of Relevant Enzymes on Lignification of Arachis hypogaea Gynophore

    • 摘要: 测定了6个花生品种果针生长发育过程中不同部位的多胺氧化酶(PAO)、过氧化物酶(POD)活性,研究了PAO、POD对花生果针人土的影响.结果表明,不同部位的PAO、POD活性不同,总的来说果针尖端活性最高,果针中部次之,果针上部最低.不同品种酶活性不同,果针生长天数对酶活性影响不大.

       

      Abstract: Polyamine oxidase(PAO) and peroxidase(POD) activities of different parts in peanut gynophores and effects of PAO and POD on peanut gynophore entering into soil were studied by using six peanut varieties.The results showed that the different parts of peanut gynophores had different PAO and POD activities which were the highest in the peak parts,the higher in the middle and the lowest in the upper;PAO and POD activities of six peanut varieties were different and days of gynophore growth had few influences to PAO and POD activities.
