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.
