- 摘要:
- 为了研究草地早熟禾抗旱机理,以黑龙江省本土草地早熟禾Blacktiger为研究材料,以美国引进品种Arcadia和Eclipe为对比材料,采用不同浓度PEG6000进行干旱条件的模拟,研究3个早熟禾品种细胞保护酶活性及质膜透性在干旱逆境下的变化规律。结果表明:PEG6000胁迫下,3个品种细胞保护酶活性大小顺序为:Blacktiger>Eclipe>Arcadia;MDA和电导率大小顺序为:Arcadia>Eclipe>Blacktiger,表明在干旱条件下,Blacktiger质膜受损程度最小,且能够通过维持较高的细胞保护酶活性来减少干旱胁迫对植物细胞造成的伤害,而具有较高的抗旱能力。
- Abstract:
- In order to study the drought resistance mechanism of Poa pratensis L.,taking Heilongjiang native Poa pratensis L.Blacktiger as material compared with the Arcadia and Eclipe which introduced from America.With the different concentrations of PEG6000 drought condition of simulation,cell protective enzyme activity and membrane permeability change of three varieties of Poa pratensisL.under drought stress were studied.The results showed that under PEG6000,cell protective enzyme activity of three varieties was Blacktiger>Eclipe>Arcadia.MDA and conductivity was Arcadia>Eclipe>Blacktiger.It showed that under the drought condition,Blacktiger plasma membrane damage was minimized,and could maintain a higher cell protective enzyme activity to reduce the damage of drought stress on plant cell,had higher drought resistance capability.
