DENDROLOGY

Detailed explanation-1: -The usual mode of seed dispersal in conifers is wind dispersal of a winged seed. This is the prevalent dispersal mode in Pinaceae, Cupressaceae, Araucariaceae, and Sciadopityaceae.

Detailed explanation-2: -Wind dispersal Seeds from plants like dandelions, swan plants and cottonwood trees are light and have feathery bristles and can be carried long distances by the wind. Some plants, like kauri and maple trees, have ‘winged’ seeds. They don’t float away but flutter to the ground.

Detailed explanation-3: -Seed from Cones In conifers, male cones produce pollen and female cones produce ovules. Seed are produced through the fertilization of an ovule by a pollen grain. In most conifers, both types of cones occur on the same tree.
