| 摘 要： | ４种经低温锻炼的柑桔愈伤组织在系列冰冻温度下，抗寒性较强的山金柑愈伤组织ＳＯＤ活性上升后回落到对照水平以下，其余３种（抗寒力较弱）则无峰值出现，ＣＡＴ活性亦以山金柑变化最为显著。细胞ＭＤＡ含量的累积与品种抗冻力发展同步。经ＳＯＤ抑制剂（ＤＤＣ，二乙基二硫代氨基甲酸钠）和外源自由基清除剂的初步试验表明：ＳＯＤ与柑桔的抗寒性密切相关。

| Abstract: | The calluses of four species in Citrus are treated with a series of cold temperature.The SOD activity of the callus of Fortunella hindsii swingle stepped up then down to the control level, butfor another species, it has no climax. Also, the CAT activity of the callus of Fortunella hindsii swinglechanged aret dramatically. The contents of MDA in cells increase as the cold - resistance hardeness. Theelemenng experiments with DDC and SBN show that SOD activity is connected with the cold - resistanceof species in Citrus. |
