【摘要】 以山东密刺黄瓜(Cucumis sativus L.)为试材,分别采用大棚土壤和露地土壤进行盆栽模拟试验,研究了苯丙烯酸对黄瓜幼苗谷胱甘肽过氧化物酶、抗坏血酸过氧化物酶和脯氨酸含量的影响。结果表明,苯丙烯酸降低了谷胱甘肽过氧化物酶活性,使抗坏血酸过氧化物酶活性和脯氨酸含量增加,说明苯丙烯酸造成了黄瓜幼苗的逆境胁迫,并随着处理浓度的增加胁迫强度增强,大棚土培幼苗的逆境胁迫大于露地土培。更多还原

【Abstract】 The tested material was Shangdong mici cucumber (Cucumis sativus L. ). We adopted respectively potted plant simulation experimentation in the soil of greenhouse and open field and studied influence of cinnamic acids on GHS-Px, AsA-POD and Proline of cucumber seedlings, the results indicated that cinnamic acids reduced GHS-Px activity, increased AsA-POD activity and content of PRO, all these illuminated that cinnamic acids worked adversity stress of cucumber seedlings, adversity stress intensity increased with treatment concentration increasing, the influence of adversity stress on the cucumber seedlings of greenhouse soil is stronger than open field.更多还原
