| 摘 要： | 以芨芨草为试材,用浓度分别为3、6、9、12、15、18 g/kg的NaCl、Na_2SO_4和NaHCO_3处理芨芨草12 d,将3种不同钠盐对芨芨草的胁迫效应进行比较,以探讨不同盐分对芨芨草胁迫的影响。结果表明:随着盐浓度的增加,芨芨草叶绿素(Chl)含量呈下降的趋势;丙二醛(MDA)含量和脯氨酸含量呈上升的趋势;超氧化物歧化酶(SOD)、过氧化氢酶(CAT)和过氧化物岐化酶(POD)的活性不同程度地呈现先上升后下降的趋势。NaHCO_3对芨芨草的伤害最大,Na_2SO_4次之,NaCl最小。

| Abstract: | A hydroponical culture experiment of Achnatherum Splendens(Trin) Nevski.was conducted to explore responses of the plants to NaCl,Na_2S0_4 and NaHCO_3 stress for 12 days in chlorophyll content,MDA content,Pro content,SOD activity,CAT activity and POD activity.The salt concentration were respectively 3,6,9,12,15 and 18 g/kg.Results indicated that with more salt concentration chlorophyll content decreased.MDA and Pro content had raised with increasing salts stress,and its content increased rapidly under NaHCO_... |
