摘　　要： 为探讨不同甘蔗品种的耐盐特性,筛选适合盐碱地区种植的甘蔗品种,本试验利用盆栽粤糖93-159、粤糖86-368和新台糖22号3个品种,并施加0.034、0.068和0.102 mol/L 3个浓度的NaC l溶液对甘蔗进行胁迫处理。结果表明,随着NaC l胁迫浓度的增加,各品种都有不同程度的Na+含量增加,质膜透性增加,叶绿素含量降低,SOD酶活性降低的现象。而新台糖22号表现出比另2个品种Na+含量更高,质膜透性增加缓慢,叶绿素含量和SOD酶活性降低更缓慢的现象,表明新台糖22号比另2个品种具有更强的耐盐特性。 In order to explore the characteristics of different sugarcane varieties resistance to salt and choose some resistant varieties for planting in saline areas,Yuetang 93-159,Yuetang 86-368 and ROC 22 were potted and treated by three concentrations（0.034,0.068 and 0.102mol/L） of NaCl solution salty stress.The results indicated that,with the increase of stress,Na＋content of 3 varieties increased with different degrees,plasma membrane permeability increased,and the chlorophyll content and SOD activity decreased.But ROC 22 had higher Na＋ content,plasma membrane permeability more slowly increased,chlorophyll content and SOD activity depressed more slowly than that of others varieties.The conclusions was drawn that ROC22 had stronger salty resistance properties than the other two varieties.
