| 摘 要： | 在聚乙二醇(PEG)-6000（20%）诱导的干旱胁迫下，小麦(Triticum aestivum L. cv. 4185)胚芽鞘及根系的生长受到抑制。胁迫初期，胚芽鞘及根系CaM水平迅速下降，之后随胁迫程度加重而逐渐积累。一定浓度（≥50 µmol/L）的CaM拮抗剂三氟拉嗪（TFP）和氯丙嗪（CPZ）均抑制小麦胚芽鞘及根系的生长，提高过氧化物酶（POD）活

| Abstract: | The growth of coleoptile and root in wheat(Triticum aestivum L. cv. 4185) was suppressed under drought stress induced by PEG-6000(20%). The CaM level of coleoptile and root decreased rapidly at first stage of stress, and then accumulated with further stress. TFP and CPZ, two CaM antagonists, could i |
