摘要:
以“通蓖5号”和“通蓖6号”2个蓖麻品种的幼苗为试材，采用盆栽控制浇水模拟干旱法，对不同程度干旱胁迫下幼苗叶片抗氧化酶活性的变化进行了研究。结果表明:“通蓖5号”和“通蓖6号”均具有较强的耐旱性。随着干旱胁迫程度的加深，蓖麻幼苗叶片抗氧化酶(SOD、CAT、POD)活性持续上升。同一土壤水分条件下，“通蓖5号”叶片抗氧化酶活性高于“通蓖6号”，说明“通蓖5号”苗期抗旱能力更强。
Abstract:
Taking ‘Tongbi No.5’ and ‘Tongbi No.6’ as materials，young seedlings of castor bean were studied in drought stress under pot culture experiments simulating different soil water regimes.And then，the change of activity of antioxidant enzymes in the leaves under drought stress were measured.The results showed that the two varieties of castor bean had strong ability of drought resistance.Under drought stress，activity of antioxidant enzyme (SOD，CAT，POD) continuously increased.Activity of antioxidant enzyme of ‘Tongbi No.5’ was higher than that of ‘Tongbi No.6’ at the same soil moisture.These results indicated that ‘Tongbi No.5’ had stronger adaptability to drought stress than that of ‘Tongbi No.6’ during the young seedlings of castor bean.
