XVI International Botanical Congess

Many endemic plant species are endangered due to the invasion of alien plants. One successful invasion is Lonicera japonica, Thunb. Plastic life history traits in invasive species can contribuite to their ability for successful naturalization. One plastic response is that of reproductive plasticity. The questions addressed are: (1) What is the germination rate of field collected seed? (2) What is the recruitment rate of seedlings in a naturalized field population? (3) What is the seed set of L. japonica contrasted to its native congener, L. sempervirens? (4) What is germination and recruitment rate of experimental field seed sowings of L. japonica? This life history research on L. japonica can be applied to conservation management practices in preserving native vegetation.
