| 摘 要： | 用0、10、20、30、40、50、60 mg/L浓度的氯化胆碱(CC)溶液分别喷施马蹄金幼苗,研究幼苗相关生理指标的动态变化.结果表明:随着处理浓度的增加,幼苗叶片中的还原糖、可溶性蛋白、叶绿素以及游离脯氨酸的含量均表现先升高后降低的趋势,但还原糖、可溶性蛋白的含量以40 mg/L时的最高,叶绿素和游离脯氨酸的含量则在50 mg/L时最高;丙二醛的含量呈现先降低后升高的态势,50 mg/L的CC时含量最低;超氧化物歧化酶(SOD),过氧化物酶(POD),过氧化氢酶(CAT)的活性在40 mg/L时上升到最高,随后逐渐降低.

| Abstract: | Dichondra repens Forst.was sprayed with 0,10,20,30,40,50,60 mg/L of choline chloride during seedling stage.The dynamic changes of several physiological indexes were studied.The results indicated that with the increase of CC concentration,the contents of reducing sugar,soluble protein,chlorophyll and free praline increased at first and decreased subsequently.With a concentration of 40 mg/L,the chlorophyll and free praline had the highest contents,but at 50 mg/L,the contents of reducing sugar,soluble protein ... |
