Abstract:
... A protocol for large-scale propagation of Phragmites communis Trin. by adventitious bud formation and plant regeneration was established. Adventitious buds were induced through either the indirect pathway or the direct pathway from stem explants of Phragmites communis. In the indirect pathway, it was essential to decrease the level of 2,4-dichlorophenoxyacetic acid from 9.1 to 0.5 μμM to induce ad ...

High-frequency embryogenesis systems were established for hybrid yellow-poplar (Liriodendron tulipifera××L. chinense) and hybrid sweetgum (Liquidambar styraciflua××L. formosana) by modifying a medium originally developed for embryogenic yellow-poplar cultures. Embryogenic cultures of both hybrids, consisting of proembryogenic masses (PEMs), were initiated from immature hybrid seeds on an induction ...
