Abstract:

To screen out a Cultivation Condition that can increase the Activity of POD，SOD and CAT in the Leaf of Pinellia ternate breit .Measurements of POD, SOD and CAT activity in the leaf of Pinellia ternate breit cultivated under different treatment were done with gaiacol, NBT and Ultraviolet spectrophotometry. The results show that the difference in leaf POD activity of Pinellia ternate breit cultivated in the two media was insignificant; but different amount of fertilizers had very significant difference on POD activity, with 1/2MS+K+P (KH2PO4 100 mg/L) being the highest; the difference in leaf SOD and CAT activity of Pinellia ternate breit cultivated in the two media was significant, activity of the two enzymes in perlite is very significantly higher than that in soil; different amount of fertilizers had some influence on SOD and CAT activity too, with 1/2MS+K+P (KH2PO4 100 mg/L) being the highest in SOD activity. The best cultivation that can enhance the POD, SOD, CAT activity in the leaf of Pinellia ternate breit is fertilizing with 1/2MS+K+P (KH2PO4 100 mg/L) in perlite.
