Abstract: The growth change of plant shoot and plant underground part, and the activities of antioxidant enzymes were studied using oriental hybrid lily‘Sorbonne’as experimental material under the different concentrations of spraying CC. The results showed that: (1) under the spraying solution of 250 mg/L, the index of plant shoot (the plant length, fresh weight of stem and leaf, the leaf length, the leaf width, the leaf thickness) and plant ground (fresh weight of bulbs and circumference) was the largest, the activity of SOD and POD was the highest, MDA content in leaves was the lowest; (2) under the spraying solution of 50-250 mg/L, MDA content decreased with the increase of the concentration of CC, the activity of SOD and POD increased with the increase of the concentration of CC; (3) under the spraying solution of 250-1000 mg/L, MDA content increased with the increase of the concentration of CC, the activity of SOD and POD decreased with the increase of the concentration of CC.
