据《园艺学报》2012年第8期《缺锌胁迫对苹果砧木幼苗抗氧化能力和激素含量的影响》(作者王金花等)报道,在人工气候室条件下,采用溶液培养法研究了缺锌胁迫对平邑甜茶(Malushupehensis Rehd.)和小金海棠(M.xiaojinensis Chenget Jiang)两种苹果砧木幼苗SOD、POD和CAT的活性,膜质过氧化水平及内源激素IAA、GA3、ZR和ABA含量的影响。结果表明,缺锌胁迫下,两品种叶片和根系中SOD活性显著下 According to “Journal of Horticulture” 2012 the eighth period “zinc deficiency stress on apple rootstock seedling antioxidant capacity and hormone content” (the author Wang Jinhua, etc.) reported that in the artificial climate chamber conditions, the use of solution culture method to study the zinc deficiency stress The activities of SOD, POD and CAT, the level of membrane lipid peroxidation and the content of endogenous hormones IAA, GA3, ZR and ABA in Malus hupehensis Rehd. And M. xiaojinensis Chenget Jiang influences. The results showed that under the zinc deficiency stress, the SOD activities in leaves and roots of two varieties were significantly lower
