Abstract:

Use tissue culture seedlings of Ziziphus jujuba Mill. ‘Zanhuangdazao’ as Use tissue culture seedlings of Ziziphus jujuba ‘Zanhuang Dazao’ as explants, effects of 6-BA, IBA and IAA on proliferation of Ziziphus jujuba were studied and selected its suitable composition in subculture. The results showed that in subculture, activity of IBA was higher, as compare with NAA. 6-BA blended with IBA can remarkably promote multiplication coefficient and quality of grow into seedlings. The best medium of Ziziphus jujuba ‘Zanhuang Dazao’ was MS+6-BA 1.5 mg/L+IBA 0.1 mg/L. The best culture conditions for the temperature (25±2)℃, light intensity 2000~3000 lx, illumination time 14 h/d.
