Terms A-G

anther

asexual

Meaning reproduction without sex.   This often refers to vegetative propagation.  Division, tissue culture and grafting all produce identical plants through asexual reproduction.  No pollen (male) or ovules (female) were involved to produce new plants.

axillary bud

A bud that grows from the axil of a leaf. An axil is the place in which the leaf is joined to the stem. These are sometimes referred to as secondary buds.

carpel(s)

Chromosome

The basic thread-like structure that carries genes.

clone (clonal)

Genetically identical individuals.

crown

diploid

Refers to peonies that contain two complete sets of chromosomes, one originating from each parent. Diploid is considered the basic configuration of chromosomes in most organisms.

disk

division

dormancy

The suspension of normal growth function by peony plants and seeds. This is often referred to as a resting state, but chemical changes are occuring in peonies during this period which are important to their growth.

filament

gene

Unit found on chromosomes which are transferred from a parent to offspring. Genes are the basic unit in heredity and are expressed as traits or may be held in a recessive state (no expression).

genetic compatibility

graft

The joined product of stem to root, as often seen in available woody peonies.

grafting

Commonly used process to propagate woody peonies, in which a scion (stem) is usually joined to a herbaceous peony’s root to produce a graft.
