Abstract:
Four varieties of roses were used as experimental materials.On the basis of nutrient solution balance for 2 days,the whole roots were naturally dehydrated for drought stress,and the leaves of each rose variety was measured every 3 hours.Drought resistant oil roses suitable for cultivation in Ningxia was screened out,in order to provide theoretical and scientific basis for the introduction of excellent drought resistant oil roses in Ningxia.The results showed that with the aggravation of drought stress, the relative water content of leaves of all rose varieties decreased gradually; the relative conductivity, proline, malondialdehyde content and superoxide dismutase activity increased gradually; the activity of peroxidase first increased and then decreased. According to the membership function analysis method, the order of drought resistance of the four roses species was ‘Russian White’>‘Lengxiang’>‘Fenghua 1’>‘Fenghua 2’.
