摘要
以适合屋顶绿化的野生藓状景天、野生垂盆草和4种园艺景天为试材,研究了干旱胁迫对植物形态、相对电导率、叶绿素含量、丙二醛(MDA)含量、脯氨酸(Pro)含量和超氧化物歧化酶(SOD)活性等生理指标与植物形态指标的影响。结果表明:6种景天抗旱性由强至弱依次为六棱景天>反曲景天>野生垂盆草>园艺垂盆草>藓状景天>金叶佛甲草。
Taking 2 wild Sedum species and 4 Sedum cultivars as materials,the effect of drought on the plant morphology, relative electric conductivity, total chlorophyll content, MDA content, proline content and superoxide dismutase （SOD） activity of the physiological indexes and morphological indexes were studied. The results showed that the drought resistance of 6 kinds of Sedum from strong to weak was Sedum sexangulare〉S, reflexum〉S, sarmentosum（wild）〉S. sarmentosum（ cultivar） 〉 S. pol ytrichoide 〉 S. lineare vat. golden.
