  • Title: [Influence of exogenous substance on germination of Platycodon grandiflorum seeds].
    Author: Zhao RM, Liu L, Guo QS.
    Journal: Zhongguo Zhong Yao Za Zhi; 2006 Jun; 31(12):966-8. PubMed ID: 17048638.
    Abstract:
    OBJECTIVE: To study of exogenous substances on the germination rate of Platycodon grandiflorum and offer the basis for the standardized culture of P. grandiflorum. METHOD: At 25 degrees C, under darkness and lightness, do pretreatmeats on seeds by using GA3, H2O2, KMnO4, PEG at different concentrations. RESULT: The 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. CONCLUSION: Pretreatment with 50-250 mg x L(-1)GA3 and H2O2 at a low cencontration could increase the seed germination of P. grandiflorum.
