The parent plant makes the spiky little burrs from the flower. seed dispersal of D. triflora is highly unlikely to be achieved by ant dispersal, and any local population extinction (including loss of soil stored seeds) should be permanent in the absence of LDD. involves methods and types of dispersal. seed. Several different vectors--wind, water, and animals --are involved in fruit and seed dispersal. But not all trees use the same technique – there are lots of ways to disperse a seed. Seeds are produced in several related groups of plants, and their manner of production distinguishes the angiosperms ("enclosed seeds") from the gymnosperms ("naked seeds").
