Studies on the Effects of Different Treatments on Flavonoids Contents in Ginkgo biloba Leaves and Their Regulating Mechanism
Abstract：From 1998 to 1999 several treatments were used for increasing flavonoids contents of Ginkgo biloba leaves in the seed-utilized ginkgo plantation.The results indicated that Ethephon(ETP),Cycocel(CCC),External ABA(EABA)could in-creased the flavonoids contents in ginkgo leaves.Among the treatments,CCC had the best significant effect;it increased the flavonoids contents by 20.06% when compared with the control(CK),and then the EABA.The CCC could reduce Gibberellin(GA)content,and 3-Indole acetic acid/Abscisic acid(IAA/ABA),IAA/Ethylene(ETH),GA/ABA,GA/ETH ratios in G.biloba leaves.
