Seedling emergence and survival of Iris lactea . var .chinensis in different vegetations

摘要

I.lactea population became dominant during the process of grassland succession when grassland was overgrazed.In general, good vegetation can restrain seed germination and seedling survival (Fenner M, 1985, 2000).In this experience, we would find how seed germinate of I.lactea and seedling survive in different vegetation condition.
