摘要：

To investigate effects of manganese (Mn) deficiency (0 mu M L-1) on concentrations of chlorophyll, superoxide dismutase (SOD) activity, biomass, and accumulations of active constituents in Glycyrrhiza uralensis Fisch., seedlings of 1-year-old G. uralensis were grown in a nutrient solution for 60 days. In this experiment, three concentrations of Mn were set up: 0 (-Mn), 7 mu M L-1, and 14 mu M L-1 Mn. The results showed that -Mn decreased the concentration of chlorophyll a with no significant differences in concentrations of chlorophyll b, total chlorophyll a + b, carotenoids, and chlorophyll a/b ratio. On days 45 and 60, SOD activity significantly decreased. However, dry weight of roots under -Mn showed no significant difference during the whole experiment. The accumulations of glycyrrhizic acid and liquiritin were significantly inhibited by Mn deficiency at different times. Thus results indicated that Mn deficiency could affect growth and contents of its secondary metabolites of G. uralensis.

Manganese deficiency in Chlamydomonas results in loss of photosystem II and MnSOD function, sensitivity to peroxides, and secondary phosphorus and iron deficiency [J].
