The only known natural example of King's Lomatia (Lomatia tasmanica) found growing in the wild is a clonal colony in Tasmania estimated to be 43,600 years old. [1]A group of 47,000 Quaking Aspen (Populus tremuloides) trees (nicknamed "Pando") in the Wasatch Mountains, Utah, United States, has been shown to be a single clone connected by the root system.
A clonal colony or genet of Quercus sinuata var. breviloba appears as thickets of ramets that may grow as high as five meters from a single extensive underground root system. [5] The clustered stems of a clonal individual may cover large geographical expanses, creating the appearance of many individual small trees or shrubs. [ 4 ]
Modular organisms are those in which a genet (or genetic individual formed from a sexually-produced zygote) asexually reproduces to form genetically identical clones called ramets. [8] A clonal colony is when the ramets of a genet live in close proximity or are physically connected. Ramets may have all of the functions needed to survive on ...
A single ramet, or apparent individual, of a clonal colony is genetically identical to all others in the same colony. The distance that a plant can move during vegetative reproduction is limited, though some plants can produce ramets from branching rhizomes or stolons that cover a wide area, often in only a few growing seasons.
It is clonal, meaning one plant or colony consists of multiple genetically identical ramets connected via a rhizome, and it is capable of both vegetative (asexual), and sexual reproduction. [1] Shoots can appear up to 30 cm apart along rhizomes, but usually less. [1]
For this reason, they often use ramets to propagate clonally. They make genetically identical copies of the healthiest organisms to spread quickly and asexually. When growth is strong and the environment is right, glassworts will produce genets, a genetically unique individual through seeds in order to keep the population diverse and evolving.
This is dependent on several assumptions, one of them that the contribution to the seed orchard crop is proportional to the number of ramets. But the more ramets the larger the share of the pollen is lost depending on ineffective self-pollination. But even considering this, the linear deployment is a very good approximation. [3]
Many trees, shrubs, nonwoody perennials, and ferns form clonal colonies by producing new rooted shoots by rhizomes or stolons, which increases the diameter of the colony. If a rooted shoot becomes detached from the colony, then fragmentation has occurred. There are several other mechanisms of natural fragmentation in plants.
