盐胁迫对龙柏的影响

采用盆栽试验,在日光温室大棚内通过设置不同盐分(Na Cl)浓度对龙柏进行胁迫试验,并对在不同盐分浓度胁迫下成活率、胞膜透性、丙二醛含量及脯氨酸含量的变化进行分析。结果表明,龙柏为强耐盐植物,在盐分浓度为5 g/kg时,成活率仍达100%;随着胁迫时间的延长,龙柏细胞膜透性、丙二醛含量及脯氨酸含量均呈现先增后降的趋势,且在一定的处理时间内均与盐溶液浓度呈正相关。

Effect of Salt Stress on Sabina chinensis cv. Kaizuka

The pot experiment in greenhouse is used to study the change of membrane system, enzyme system and praline of Sabina chinensis cv. Kaizuka under different salt stress. The result shows that Sabina chinensis as the strong salt-tolerant plants, under 5 g/kg salt concentration, the survival rate is 100%; as the extension of stress time, Sabina chinensis cell membrane permeability, MDA content and PRO content increased after the first drop trends. The correlation analysis showed that there is a significantly linear positive correlation between them in a certain processing time.
