采用浓度为１００ｍｇ／ｋｇ的ＧＡ３和ＰＰ３３３浸种，研究了小麦形态和生理指标对药剂处理的反应。结果表明，ＰＰ３３３处理抑制了植株地上部生长，增强生根力，增加根／冠和植株体内脯氨酸含量，提高超氧化物歧化酶（ＳＯＤ）和ＩＡＡ氧化酶活性。但却降低了过氧化物酶（ＰＯＤ）、淀粉酶活性及细胞膜透性。ＧＡ３则促进地上部生长，降低根／冠及ＩＡＡ氧化酶活性，提高淀粉酶和ＰＯＤ活性，ＳＯＤ活性略增强。表明２种调节剂对小麦幼苗的生长具有相反效应
GA3 and PP333 seed soaking at a concentration of 100 mg / kg was used to study the response of wheat morphology and physiological parameters to the treatment. The results showed that PP333 inhibited shoot growth, increased rooting ability, increased proline content in roots / crowns and plants, and increased SOD and IAA oxidase activities. But reduced peroxidase (POD), amylase activity and cell membrane permeability. GA3 promoted shoot growth, decreased root / shoot and IAA oxidase activity, increased amylase and POD activity, and slightly increased SOD activity. The results showed that the two regulators had the opposite effect on the growth of wheat seedlings
