Inhibition Effect of Extraction from Seed of Phoebe Bournei

Abstract:

In order to approach the dormant property of Phoebe bournei seeds, the inhibition effects of the different concentrations and different solvent extraction from seed coats and embryo of Phoebe bournei was studied through bioassay method.The results showed that there were inhibition effects of extracts on the germination and radical growing of cabbage seeds, and the inhibition effects became stronger as the contents of extracting solutions increased.Germination rate of cabbages in seed embryo extracts was lower than that in the seed coat extracts in the same concentrations, and the radical length in the seed embryo extracts was also shorter than that in the seed coat extracts. The seed embryo and coat extractions phase of ethyl acetate on the germination and radical growing of cabbage seeds had the strongest inhibition effect. The results indicated that inhibiting substances were existed both in the seed coats and embryo of Phoebe bournei seeds, and embryo extracts had stronger inhibition effect on the seed germination and radical growing of cabbage seed than the seed coats extracts had, and the inhibiting substances were mainly soluble in the methanol and ethyl acetate.
