Abstract

Abstract: The study was to reveal effects of exogenous ABA on chilling resistance of Phalaenopsis seedlings under low temperature stress. Leaves were sprayed with 50 mg·L-1 ABA under room temperature for 1 day， and then plants were treated under 6℃ for 4 days. Plants treated with water were used as the control. Relative electric conductivity(REC)， malondialdehyde （MDA） and proline content， and activities of catalase （CAT） and superoxide dismutase （SOD） were determined on four days after cold treatment. The results showed that ABA treatment delayed the increase of REC and MDA content， reduced the accumulation of proline， and increased the activities of SOD and CAT. These above results indicated ABA treatment could increase the activities of antioxidant enzymes， reduce the reaction of membrane lipid peroxidation and the infiltration of membrane， and thus decrease the damage under low temperature in Phalaenopsis plants.

Key words: ABA, Phalaenopsis, low temperature, relative electric conductivity, malondialdehyde, proline, antioxidant enzyme
