Effects of plant growth regulators on proliferation and rootage of Anoectochilus formosanus test-tube plantlets

Cen Xiu-fen et al(Agriculture College of Guangxi University,Nanning 530005,China)  
To study the effects of plant growth regulators on proliferation and rootage of Anoectochilus formosanus test-tube plantlets.Aseptic A.formosanu test-tube plantlets were used as tested material,the effects of 6-BA,6-BA+NAA and 6-BA+IBA on bud proliferation were studed,then the effects of NAA,IBA,NAA+MET and IBA+MET on rooting induction were compared.[Result]6-BA combined with NAA had the best effect on bud proliferation while NAA combined with MET had the best effect on rootage of test-tube plantlets of A.formosanus.As far as test-tube plantlets of A.formosanus are concerned,the suitable combination and concentration for bud proliferation are 6-BA4.0mg / L+NAA0.2mg / L and the suitable combination and concentration for rootage are NAA4.0mg/L+MET0.5mg/L.
