Abstract: The effects of desiccation on relative electrical conductivity, germination percentage and germination indexes of Cyclobalanopsis glauca, Elaeocarpus sylvestris, Sapindus mukorossi, Tsoongiodendron odorum, Lindera communis and Michelia foveolata seeds were studied. The results showed that except for S. mukorossi, the relative electrical conductivity of other five species has a gradual increasing trend and their germination indexes have a significant decrease with the prolonging period of desiccation. The seed germination percentage of all six species has a trend of decrease with the bitter of desiccation, but the extent and process of reduction is quite different. Among the species studied, S. mukorossi can be classified as sub-orthodox seeds. The other five species are between orthodox and recalcitrant seeds. Among them, C. glauca is the most tolerant species to desiccation, Elaeocarpus sylvestris is the second. The desiccation tolerance of T. odorum, M. foveolata and L. communis is not so good.
