【 摘 要 】

The effects of recovery growth were compared by measuring the biomass and quality indices when dormancy-released Sedum aizoon L. were treated at 25°C, 20°C and 15°C respectively. The results showed that with the increasing temperature, the plant height and aboveground fresh weight all showed an upward first and then downward trend. The contents of chlorophyll, carotenoids, calcium and zinc all showed an upward trend, while magnesium and iron all showed a downward first and then upward trend in fresh food part. The contents of soluble protein, vitamin C, free amino acid and flavonoid all showed a downward trend, while total soluble sugar, caffeine and oleanolic acid all showed an upward first and then downward trend. The plant height, aboveground fresh weight, the total chlorophyll to carotenoid ratio, the contents of total soluble sugar, caffeine and oleanolic acid were all the highest under 20°. In conclusion, the best recovery growth temperature was 20° for dormancy-released Sedum aizoon L.
