| 中文摘要: |
| 对 6 个油橄榄品种进行低温胁迫（5、0、-5、-10℃）处理，应用电导率法及 Logistic 方程测定不同油橄榄
品种的抗寒性。 结果表明，油橄榄叶片相对电导率随着处理温度的不断降低而呈野S冶型曲线变化，叶片伤害率变化趋
势与叶片相对电导率基本一致；在相同处理温度下叶片伤害率和相对电导率有较大差异，间接反映了不同品种的抗
寒性强弱，结合 Logistic 方程可计算油橄榄的半致死温度（LT50）；油橄榄叶片 SOD、POD、CAT 酶活性随胁迫温度的降
低总体上均呈先升高后下降的趋势，其中皮削利的 3 种酶活性均显著高于其他品种；6 个品种的油橄榄抗寒性差异

| 英文摘要: |
| Under low temperature stress(5, 0, -5, -10) on 6 olive varieties, the results indicated that the leaf relative
conductivity increased as temperature decreasing, presenting Stype curve change. The trend of leaf damage rate was
consistent with the relative electric conductivity. The leaf damage rate and electric relative conductivity were different
significantly in 6 varieties of olive leaves at the same treatment temperature, indirectly reflected the cold tolerance of
different varieties of olive. The semilethal temperature (LT50) was conducted by using conductance method with Logistic
Equation. The activity of SOD, POD and CAT generally increased first and then decreased with the temperature decreasing,
the enzyme activity of Picholine was significantly higher than that of other varieties. The cold tolerance was different
significantly in 6 cultivars, the hardiness of the tested cultivars was listed as Picholine﹥Pendolino﹥Leccino﹥Ascolana
Tenera﹥Ezhi 8﹥Frantonio. |
