Abstract:
To investigate the effect of warming on the physiological compensation of lily in the 10 leaf stage,20 leaf stage and bud stage after low temperature stress,a lily cut flower variety,Lilium oriental Hybrids ‘Sorbonne’,was used in the present study.The room temperature(22 ℃/14 ℃ for day/night) was used as the control (CK),and the artificial climate chamber was used to simulate the low temperature environment (8 ℃/2 ℃) for 3,7,10 days,immediately increase to room temperature.Then,determine the activity of superoxide dismutase (SOD),peroxidase (POD) and catalase (CAT),relative conductivity (REC),proline (Pro) and soluble sugar via nitroblue tetrazolium (NBT) photochemical reduction method and other conventional methods,which could provide a theoretical basis for temperature regulation of solar greenhouse in winter and technical reference for planting management of cut flower lily.The results showed that compared with CK,the activities of SOD,POD，CAT,and the relative electrical conductivity (REC),proline (Pro),soluble sugar content of lily leaves increased with the prolongation of treatment time under low temperature stress.After 10 days of stress,they reached 0.97-2.33,2.05-5.26,1.84-2.14,2.40-2.49,0.87-1.87,1.77-5.33 times of CK,respectively.The activities of SOD,POD and CAT,the contents of REC,Pro and soluble sugar all decreased with the increase of treatment time after warming.After 10 days of warming,each index tends to CK at each stage,which was 1.03-1.26,1.12-2.18,1.02-1.12,1.35-1.72,0.87-1.03,0.56-1.32 times of CK,respectively.The activity of antioxidant enzymes (SOD,POD,CAT),relative electric conductivities and soluble sugar content of lily leaves changed most with temperature during the whole treatment,and increasing the temperature after low temperature stress could alleviate the physiological damage of Lilium oriental Hybrids ‘Sorbonne’ in different growth stages.
