水分胁迫下脱落酸及磷脂酶在玉米幼苗根系渗透调节物质积累中的信号作用

Signal effects of ABA and phospholipase on the osmotica accumulated in roots of maize seedling under water stress

    摘要
  • 摘要: 试验研究了水分胁迫下、脱落酸(ABA)、PLD／PLC抑制剂新霉素硫酸盐及脱落酸合成抑制剂Ancymidol在玉米幼苗根系渗透调节物质积累中的信号作用，结果表明水分胁迫下脱落酸可促进脯氨酸、可溶性糖和Ca2+ 的积累，但不能促进游离氨基酸和K+ 的积累，且PLD／PLC可能对脯氨酸、可溶性糖和游离氨基酸的积累有一定促进作用，但对K+ 和Caz2+ 的积累不起作用。

     

    Abstract: The study on the signal effects of ABA，neomycin sulfate(PLD／PLC inhibitor)，ancymidol(ABA inhibitor)on the osmotica accumulated in roots of maize seedling under water stress shows that ABA can promote the accumulation of proline，soluble sugars and Ca2+ ，but can not promote the accumulation of free amino acid and K+ ，and the PLD／PLC maybe promote the accumulation of proline，soluble sugars and free amino acid，but can not promote the accumulation of K+ and Ca2+ ．
