摘  要:
通过测定平榛(Corylus heterphylla)在水分胁迫下脯氨酸含量(Pro)、丙二醛含量(MDA)、相对电导率、叶绿素总含量及SOD活性5项生理指标,综合评价平榛的抗旱性。结果表明,随着水分胁迫天数的增加,平榛的脯氨酸含量显著升高;丙二醛含量、相对电导率呈缓慢上升趋势,细胞膜透性增大;叶绿素总含量略上升后下降;SOD活性变化比较复杂,但总体趋势为先上升后下降。综合分析表明,平榛对干旱环境具有较强的适应性。

摘  要:
The drought-resistance of Corylus heterphylla was evaluated comprehensively by measuring five physiological indices under water stress including proline content(Pro),malondialdehyde content(MDA),relative conductivity,total chloro-phyll content and SOD activity.The results showed that with the increase of water stress period,the proline content in Corylus heterphylla was increased significantly;MDA content and relative conductivity increased slowly;cell membrane permeability increased;the total chlorophyll content increased first and then decreased slightly;the change of SOD activity was much complicated,but the overall trend declined after rising in the beginning.Comprehensive analysis indicated that Corylus heterphylla has strong adaptability in drought conditions.
