- 摘要:
- 以草莓“香菲”和“大将军”为试材，研究了一定浓度的细胞分裂素（6-BA）和生长素（IAA）协同处理对盐胁迫下草莓试管苗叶片酶活性的影响。结果表明：15 d后，0.5 mg/L的IAA和6-BA处理0.3%盐胁迫下的试管苗生长趋于正常，体内丙二醛含量降低，保护酶超氧化物歧化酶（SOD）、过氧化物酶（POD）以及过氧化氢酶（CAT）活性增强，盐胁迫危害程度减轻。
- Abstract:
- Taking the strawberry cultivar ‘Xiangfei’ and ‘Dajiangjun’ as test materials，the mitigative effect of a certain concentration of exogenous 6-BA and IAA on the activity of membrane protective enzymes of strawberry plantlets under certain salt stress in vitro were studied.The results showed that after 15 days in vitro culture，compared with those which grew under salt stress，the treatments with 0.5 mg/L 6-BA and 0.5 mg/L IAA which strawberry plantlets were inoculated in medium with 0.3 percent NaCl could comparatively delay the accumulation of malondialdehy (MDA)，relatively promote the activity of membrane protective enzymes such as superoxide dismutase (SOD)，peroxidase (POD) and catalase (CAT).And the harmful levels of salt stress were reduced，the plantlets become normal.
