    Abstract : The seeds of wildflower V icia uni juga A. . were studied on the basis of the germination

    in this paper . The nature of the germination of the seeds of V icia uni juga A. were researched

    systemically in order to provide theoretical basis for it s being int roduced and cultivated. The result

    showed that the seeds are green - gray or brown - black , about 5 mm long ,oblate. The weight per

    thousand - granule was 211310 g. And they are minimal - medium seeds. The dormant character of

    the seeds of V icia ani juga A. was forcing dormancy caused by hard seed vessels. The dormancy

    could be broken down by sulphuric acid. The most appropriate time was 30 min. The highest

    germination rate and index of the and the highest germination power were 93 % , 19185 , 72 %

    respectively. The optimum germination temperature of the seeds of V icia ani juga A. was 20～

    30 ℃. It indicated that illumination somehow rest rained the germination of the seeds of V icia

    ani juga A.
