17 Questions
What is the term for a rooted stem that is detached from a mother plant?
Layer
Which of the following plants is propagated by mound layering?
Apple rootstock
What is an advantage of layering compared to other propagation methods?
It allows for the propagation of a relatively small number of large-size plants
Why is layering still used today despite being an ancient technique?
It is used for species that are very hard to reproduce by other means
What is a limitation of layering compared to other propagation methods?
It requires a large amount of supplies and facilities
What is an example of a species that uses layering as a natural means of asexual reproduction?
Bermuda grass
What is the primary purpose of using mound layering in fruit tree propagation?
To mass-propagate clonal fruit tree rootstocks
What is the consequence of disturbing roots when cutting the plant back to 1 inch above ground level in the second year?
It leads to poor root formation and reduced clonal propagation
What is the typical outcome of mound layering in the first year after cutting the plant back to 1 inch above ground level?
Two to five shoots normally develop from the crown, with roots forming in the second year
Why is it important to plant the stock plants in fertile, well-drained soil before starting mound layering?
To develop a vigorous plant with a well-formed root system
What is the primary advantage of using mound layering over other layering techniques?
It is a highly mechanized technique, suitable for mass propagation
What is the limitation of using mound layering in fruit tree propagation?
It is sensitive to timing and soil conditions
What is the main purpose of the 'rat-tail' appearance in vegetative shoots?
To facilitate rooting when in contact with a suitable medium
What type of stem produces new 'daughter plants' at the nodes when growing horizontally?
Stolon
What is a key difference between runners and stolons?
Runners lack leaves, while stolons have leaves
What is an advantage of using stolons, runners, and rhizomes for asexual propagation?
They enable rapid colonization and spreading of a plant species
What can be done to the 'daughter plants' produced by stolons, runners, and rhizomes to create new, independent plants?
They can be cut off between the nodes and treated like naturally occurring rooted layers
Learn about the mound layering technique used to propagate clonal fruit tree rootstocks. This method requires healthy stock plants, fertile soil, and timely execution to avoid damage. Test your knowledge of this important horticulture technique.
