Abstract

Abstract:

In order to explore the effects of different drought stresses on the growth of Hydrangea varieties and evaluate their drought resistance, six Hydrangea varieties were used as test materials, and were treated with normal (CK), mild drought stress (T1), moderate drought stress (T2), severe drought stress (T3) and extra severe drought stress (T4) to simulate drought stress. Their biomass, root-shoot ratio, leaf relative water content, cell membrane permeability, chlorophyll (Chl) and carotenoid (Car), malondialdehyde (MDA), proline (Pro), peroxidase (POD), superoxide dismutase (SOD), soluble sugar (SS) and soluble protein (SP) were measured. Under drought stress, the biomass and relative water content of each Hydrangea variety showed a downward trend, while the root-shoot ratio, relative conductivity, MDA, Pro and SS showed an upward trend. However, the increase range of each variety was different. SOD, POD and SP showed an upward trend first and then a decreased trend. The change rule of photosynthetic pigment of Hydrangea was not obvious. The order of drought resistance of 6 Hydrangea varieties from strong to weak was as follows: Mangek you>Love You Kiss>Corsage>White Angel>Stockings>Summer Sacrifice.

Key words: Hydrangea, drought resistance evaluation, principal component analysis, subordination function method, cluster analysis
