Abstract:
OBJECTIVETo study of exogenous substances on the germination rate of Platycodon grandiflorum and offer the basis for the standardized culture of P. grandiflorum.
METHODAt 25 degrees C, under darkness and lightness, do pretreatmeats on seeds by using GA3, H2O2, KMnO4, PEG at different concentrations.
RESULTThe results indicated that the pretreatments with GA3 at a concentrating of 50-250 mg x L(-1) and 1%-2% of H2O2 could increase germination of P. grandiflorum seed at a certain degree. Contrariwise 0.1%-0.5% of KMnO4 and 15%-35% of PEG inhibited the germination.
CONCLUSIONPretreatment with 50-250 mg x L(-1)GA3 and H2O2 at a low cencontration could increase the seed germination of P. grandiflorum.
