Effects of different fertilizer combinations on total polyphenols contents and antioxidant activities of the cakes of Camellia vietnamensis T.C.Huang ex Hu
An attempt was made to explore the effects of different fertilizer combinations on the total polyphenol content and antioxidant activity of the cakes of Camellia vietnamensis T.C.Huang ex Hu,improve the fertilizer application methods for C.vietnamensis in Hainan,and promote the healthy development of the C.vietnamensis industry.C.vietnamensis trees with similar growth and vigor were selected and treated with different fertilizer combinations(compound fertilizer(Ml),compound fertilizer with earthworm soil(M2),compound fertilizer with vermicompost and biological fertilizer(M3),compound fertilizer with slow-release medium-trace element fertilizer(M4),compound fertilizer with the special plant regulator compound fertilizer(M5)with no fertilizer as the control(CK)in an experiment,and a randomized complete block design was arranged with 3 plots,6 trees per plot.The contents of total polyphenols in the extracts of the cakes of C.vietnamensis were determined under different fertilizer treatments.The antioxidant activities of the extracts were determined by using FRAP test,DPPH radical scavenging,hydroxyl radical(—OH)scavenging and ABTS radical scavenging.The results showed that the total polyphenol content and antioxidant activity of the cakes were higher in the treatments M1,M3 and M4 than in the CK,and the total polyphenol content and antioxidant activity of the cakes in the treatment M4 were the highest.Moreover,the addition of slow-release medium-trace element fertilizer on the basis of compound fertilizer could further enhance the total polyphenol content and antioxidant activity of the cakes.Therefore,the quality of the cakes of C.vietnamensis can be improved by applying compound fertilizer with slow-release medium-trace element fertilizer in actual production.
