What is a provenance test?

Provenance tests are studies where genotypes from different sources (or provenances) within a tree species are planted onto a common, relatively homogeneous, site. Often those sources can represent the entire species range- or just a limited subset of that range.

What is provenance tree?

Generally, tree provenance studies involve collecting representative seed of natural populations from a variety of locations (also referred to as provenances) across the range of a species and subsequently planting them at one or more test sites with statistically sound experimental designs.

What is ortet and Ramet?

Ramet- A vegetatively reproduced copy of a plant. Each ramet will have almost precisely the same genotype as the original parent tree, known as the ortet. (See clone and ortet.)

What is the difference between forestry and silviculture?

The NOAD reports that silviculture means the growing and cultivation of trees, while forestry means the science or practice of planting, managing, and caring for forests.

What is plus tree?

Plus tree / Select / Superior ❖ A tree that has been recommended for production or breeding following grading. ❖ It has a superior phenotype for growth, form, wood. quality or other desired characteristics and appears to be adaptable.

Why do we need tree Improvement?

Tree improvement refers to the application of forest genetics principles within a given silvicultural system for the purpose of improving the genetic quality of the forest. Its goal is to improve the genetic value of the population while maintaining genetic diversity.

Why provenance testing is important in tree breeding?

Provenance Trials: After selection of suitable species it is important that the most suitable seed source for planting site is selected. This is accomplished by selecting suitable provenances. Provenance is the area on which any stand of tree is growing.

What is seed provenance?

seed provenance is ‘where the seed comes from’. In other words, where – geographically – the parent trees grow and the seed is collected (rather than e.g. coming from the DIY store, or a supplier). It is our ‘bio-geographic habitat region’!

What do you mean by ramet?

Definition of ramet : an independent member of a clone.

What is clone and ramet?

Clone is a genetically identical individual which is formed as a result of mitotic division in a somatic cell. Ramet is a clonal colony which consists of group of genetically identical individual grown in a particular location. all originating vegetatively, not sexually, from a single ancestor.

What are examples of silviculture?

Activities can include tree planting, herbaceous weed control, fertilization, precommercial thinning, commercial thinning, final harvests, harvests for habitat improvement, preservation, road construction, road obliteration, and prescribed fire, among others.

What is the difference between a forester and an arborist?

Arborists care for individual trees while foresters manage populations of trees. For example, a forester may be responsible for managing a forest or woodlot for the production of timber or other wood products.

What is the meaning of the word provenance?

Definition of provenance 1 : origin, source 2 : the history of ownership of a valued object or work of art or literature Examples of provenance in a Sentence

What is the origin and provenance of a plant?

The National Plant Specification – Origin and Provenance Usage The terms origin and provenance have not been widely used by specifiers and providers in amenity sectors of the plant supply chain where the bulk of trading has been in vegetatively propagated varieties. The terms have however been in constant use in forestry.

Why are experts interested in provenance of an item?

Experts are interested in the provenance of an item for several reasons, the most important of which is that well-documented provenance helps confirm that an item is authentic. Undocumented gaps of time in an object’s history could indicate that the item may be a forgery with a fabricated history.

Why choose a career in forestry?

Not only that, but the work is often in beautiful areas with no desks or cubicles in sight. A significant part of many forestry careers is ensuring natural areas stay healthy, or helping restore wellness through propagation, remediation, compliance and fire prevention.
