Experiment on ex situ conservation of wild Lilum spp.germplasm

Several wild Lilium spp.such as L.Leucanthum,L.davidii,L.dauricum,L.distichum,L.tigrinum,L.brownii et al.were introduced in Shanghai and Nanjing to conserve germplasm with simple cultivated facility.The result showed that several Lilium spp.except L.distichum were well adapted to the climate of East China.The phenophase of germplasm from north-east of China such as L.dauricum and L.tigrinum had been advanced compared to that in original locality.The phenophase of germplasm from south-west of China was advanced a little bit.The phenophase of germplasm from east of China was the same as in the habitat.Their growth of stem height,flowering and propagation were normal except for L.distichum.Some of germplasm have also seeded.We suggested that the ex situ conservation for Lilium spp.germplasm in East of China be feasible.
