- 摘要:
- 以‘美22’‘哈瑞太兹’‘秋福’和‘秋萍’4个树莓栽培品种组培苗为试材，采用盆栽方法，研究不同浓度混合盐胁迫对其部分生理指标的影响，并采用隶属函数法对4个树莓栽培品种的耐盐性进行综合评价。结果表明：随着混合盐浓度的升高，4个树莓品种叶片相对电导率均呈逐渐增加趋势；‘哈瑞太兹’叶片丙二醛（MDA）含量呈下降-升高的趋势，而其它3个品种叶片MDA含量均显著高于各自对照。4个树莓品种叶片超氧化物歧化酶（SOD）和过氧化物酶（POD）活性呈交替变化，并通过二者的互补作用来降低氧化伤害。各品种树莓叶片可溶性糖含量总体呈增加趋势；‘哈瑞太兹’‘秋萍’叶片可溶性蛋白质含量呈升高-下降的趋势，而‘美22’‘秋福’叶片可溶性蛋白质含量均低于各自对照；‘秋福’‘秋萍’叶片游离脯氨酸含量呈显著增加趋势，而‘美22’‘哈瑞太兹’叶片游离脯氨酸含量均较各自对照呈不同幅度下降。4个树莓栽培品种叶片叶绿素含量均呈升高-下降的趋势。隶属函数法分析得出，4个树莓栽培品种的耐盐性由强到弱依次为‘秋萍’‘秋福’‘哈瑞太兹’‘美22’。
- Abstract:
- The effects of mixed salt stress with different concentrations on some physiological indexes in pot-cultured ‘America 22’‘Heritage’‘Autumn Bliss’‘Qiuping’ seedlings were studied,and the salt tolerance of the four raspberry varieties was comprehensively evaluated by using subordinate functions.The results demonstrated that with the increase of mixed salt concentration,the relative conductivity in the leaves of the four raspberry varieties all showed a gradually increasing trend.MDA content in the leaves of ‘Heritage’ presented a decreasing-increasing trend,while MDA contents in the leaves of the other three varieties were all significantly higher than their controls,respectively.SOD and POD activities in the leaves of the four raspberry varieties showed an alternating change,and the complementation between them reduced oxidative damage.Soluble sugar content in the leaves of all the raspberry varieties presented an overall increasing trend.Soluble protein contents in the leaves of ‘Heritage’ and ‘Qiuping’ showed an increasing-decreasing trend,while soluble protein contents in the leaves of ‘America 22’ and ‘Autumn Bliss’ were lower than their controls,respectively.Free proline content in the leaves of ‘Autumn Bliss’ and ‘Qiuping’ presented a significantly increasing trend,while free proline content in the leaves of ‘America 22’ and ‘Heritage’ showed a decrease at different degrees as compared with their controls,respectively.Chlorophyll content in the leaves of the four raspberry varieties all presented an increasing-decreasing trend.Subordinate function analysis revealed that the salt tolerance of the four raspberry varieties from strong to weak was ‘Qiuping’‘Autumn Bliss’‘Heritage’ and ‘America 22’.
