Sexual Reproduction: Cones
Coniferous trees reproduce sexually by forming cones which contain seeds. Examples are Pine (Pinus spp.), Spruce (Picea spp.), and Fir (Abies spp.)
Sexual Reproduction: Flowers
Flowering trees reproduce sexually through pollination. Examples include Apple (Malus domestica), Cherry (Prunus spp.), and Magnolia (Magnolia spp.)
Asexual Reproduction: Apomixis
Apomixis is a form of asexual reproduction where seeds are produced without fertilization. An example is the Common dandelion (Taraxacum officinale). Not common in trees but present in some plant species.
Asexual Reproduction: Stolons or Runners
Certain tree species reproduce by extending stolons or runners. Strawberry tree (Arbutus unedo) and some bamboo species (e.g., Phyllostachys spp.) use this method.
Asexual Reproduction: Coppicing
Trees that are cut down can regrow from the stump. This method is known as coppicing. Species like Willow (Salix spp.), Oak (Quercus spp.), and Hazel (Corylus spp.) are traditionally coppiced.
Asexual Reproduction: Root Suckers
Some trees reproduce asexually through root suckers, leading to clonal colonies. Examples include Aspen (Populus tremuloides), Hazel (Corylus spp.), and Elm (Ulmus spp.)
Asexual Reproduction: Layering
Layering involves the formation of roots on a stem while still attached to the parent plant. Examples include Rhododendron spp. and some species of Magnolia.
Asexual Reproduction: Grafting
Grafting involves the joining of two tree parts so that they grow as one. Fruit trees like Apples (Malus domestica), Pears (Pyrus spp.), and Citrus spp. are often grafted to improve fruit quality.
Asexual Reproduction: Cuttings
Tree cuttings involve taking a part of a tree, such as a stem or leaf, and encouraging it to grow into a new tree. Willow (Salix spp.) and Poplar (Populus spp.) are commonly propagated via cuttings.
Sexual Reproduction: Wind Pollination
Several trees rely on wind for pollination, capable of dispersing their pollen over long distances. Examples include Oak (Quercus spp.), Birch (Betula spp.), and Maple (Acer spp.)
