- 摘要:
- 为了挖掘早熟禾抗旱机理,以黑龙江硬质早熟禾作为供试材料,与国外引进品种统治者、印第安酋长进行比较,采用连续干旱胁迫及复水处理,研究其细胞保护酶活性与抗旱性相适应的关系。结果表明:干旱胁迫下,3个品种的超氧化物歧化酶(SOD)、过氧化物酶(POD)及过氧化氢酶(CAT)的活性大小依次为:硬质早熟禾>印第安酋长>统治者,表明硬质早熟禾在复水后其细胞内过氧化氢酶的活力恢复速度最快。
- Abstract:
- In order to excavate the drought resisitance mechanism of Kentucky bluegrass,taking native bluegrass Poa sphondylodes T. as material,the native bluegrass and varieties Reubens and Ruler introduced from abroad were compared.Through continuous drought stress and re-watering treatment,the resistance of cell protective enzyme activity and drought phase adjustment was studied.〖JP2〗The results showed that three varieties including super oxide dismutase(SOD),peroxides(POD)and catalyses(CAT)had different activities under drought stress,the order of activities of protective enzymes was Poa sphondylodes T.>Reubens>Ruler.
