摘要
以玉米自交系为材料,研究不同低温处理及不同处理时间对离体叶片过氧化物酶(peroxidase,POD)活性的影响。结果表明不同低温、不同处理时间以及处理温度与时间对POD活性都有极显著影响;处理温度对POD活性的影响程度大于处理时间;3种温度下,-20℃的不同时间测定的POD活性变化较小。
Isolated leaves of maize (Zea mays L.) were stored at different low temperatures for different duration of time before POD (peroxidase) activity determination. All the treatments (low temperature, treatment duration and their combinations) significantly affected POD activity. Difference in treatment temperature had greater effect than difference in stress duration. Of the 3 temperatures adopted in the treatments, POD activity under –20℃ appeared more stable than under the other two.
