摘　　要：本实验以锌作为重金属胁迫因子,用一定测试手段探讨单一锌胁迫对油橄榄的活性叶片丙二醛(MDA)、游离脯氨酸(Pro)含量、可溶性蛋白、超氧化物歧化酶(SOD)、POD、APX、CAT等生理因子的影响。结果表明:在低浓度锌胁迫下,丙二醛含量基本没有发生变化,高浓度锌胁迫下,丙二醛含量急剧增加;Pro含量与Zn浓度呈正相关;可溶性蛋白在Zn胁迫浓度达到260mg/kg后,可溶性蛋白含量达到最高且基本稳定,在Zn浓度为325mg/kg时含量下降但不明显;Zn胁迫下,随着Zn处理浓度增大,SOD活性降低,而POD活性增强,APX、CAT活性则先上升后下降。Pick to the experiment to zinc as heavy metal stress factor of olive leaf malondialdehyde （MDA） and free amino acid（Pro） content, soluble protein, super oxide claw （SOD）, POD, CAT physiological factor. The results show that under the stress of lowzinc concentration, malondialdehyde（MDA） content is basic no change, under high concentration of zinc stress, MDA content increaseddramatically; Pro content and zinc concentrations were positively correlated; Soluble protein in recent stress concentration of 260 mg/kg, reached the highest content of soluble protein and basically stable, when zinc concentration of 325 mg/kg levels drop, but not obvi-ous; Under recent stress, along with the increasing concentration of zinc processing SOD activity, POD activity increased, APX andCAT activity increased and first.
