Be aimed at afore-mentioned problems, we began a series of relevant research in recent years, obtained corresponding research result, for Chinese begonia the species that belong to establish pledges long-term and effective protection provided resource relevant and theoretical foundation and technical system. Obtains research belongs to plant species to pledge the long-term and effective protection of resource diversity has important sense to Chinese begonia not only as a result, still will be how to undertake some kind the effective protection of group of plant resource provides the experience that is worth to draw lessons from and relevant technology and means, in the meantime, be in those who begin plant species to pledge had arrived since respect of resource protection job to set an example to domestic and international arboretum action.
