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.
