A protocol for in vitro induction of crape myrtle tetraploids using nodes from in vitro-grown shoots (2n = 48) was established. Nodal buds were excised from in vitro-grown shoots, maintained on proliferation medium containing Murashige and Skoog medium supplemented with 4.44 μM 6-benzyladenine , 0.54 μM α-naphthaleneacetic acid, and treated with a range of(More)

The main object of this study is using embryo culture in vitro to get the seedling directly and to improve the succeed rate of cross breeding. The factors that influenced the embryo culture(More)
Two assays were conducted to investigate the changes of faba bean (Vicia faba L.) and azuki bean (Vigna angularis L.) phosphatases (phytase [Phy] and acid phosphatase [AcPh]) and the degradation of its substrates (inositol phosphate esters) during seed germination. The 1st assay was to establish the optimal germination conditions of faba bean and azuki bean(More)
