| Abstract: | Using 4-year-old petals of Magnolia denudata,M.liliflora and M.×soulangeana as materials,super-cooling points,semi-lethal temperature and browning rate were evaluated after the treatment of artificial frost box to determine the critical temperature of cold in 3 petals of Magnolia.The results show that the critical temperature of cold in M.denudata ranged between-5.46——3.85 ℃,M.liliflora between-5.81——4.83 ℃ and M.×soulangeana between-5.73——4.03 ℃,and as the development of the floral organs,the critical temperature of cold increased and the floral organs became more sensitive to low temperature.So protection against cold to Magnolia should be taken during the full blossom period. |
