Sometimes a similar situation occurs in the fall as the leaves begin to change. Each of the pockets or clumps originated from differing parent stock. As they mature these individually identical groups of new growth are referred to as clone clumps.Īs you travel around the region this spring you may see pockets or clumps of aspen leafing out, while adjoining trees are still bare this is an example of the genetic variation in these clone clumps. Should a tree become severely damaged or killed, thousands of shoots can develop from the expanse of the parent trees root distribution. Although they do produce seed that will germinate into new plants with differing genetics their primary reproduction is by way of sprouts from their roots. tremuloides) also use vegetative reproduction to help sustain them. The Lombardi popular trees we see are all male and produce no seed all reproduction is from cuttings or sprouts with no genetic variation. Parent stock is found in the Lombardi Providence of Italy. Less popular now than they once were in this country, these fast growing unique shaped trees are all genetically matched clones.
nigra Italica), those very erect tightly branched trees commonly in use as windbreaks and ornamentals, are another example of clones. Both are examples of vegetative reproduction where the new plants are genetic matches to the parent plants. Segments of grape vine will develop roots if in contact with moist soil willow cuttings can be encouraged to root if left in water or damp soil. Many tree species utilize vegetative reproduction as a primary means of reestablishment. In the plant world and with some single celled creatures cloning is a natural and common form of reproduction. Genetically identically matched individuals, or clones, are a primary regeneration method for some of our more common forest and landscape species.Īrtificial cloning of animal species has been in the news of late and for many is controversial. Vegetative reproduction of plants produces new growth that is an exact genetic match to the parent stock.
