Perennial Grass Growth and Development Glossary

The part of the stamen (part of the male reproductive structure) that develops and holds pollen; supported by the filament

tissue at the tip of a plant shoot that causes new growth.

a bud growing from the axil of a leaf (where the leaf connects to the stem).

buds at the crown of a plant capable of producing new tillers.

linear elongated leaf.

the stage of plant growth when the seed head begins to push through the upper leaf sheath

a grass that grows in a more upright fashion creating “bunches” as opposed to spreading out laterally.

when the upper part of leaves spread out in such a way to shade or cover the ground.

where the blade and leaf sheath meet on a grass plant.

the stem base of the plant.

The elongated stem resulting from internode elongation.

cutting or removing leaf tissue.

When plant cells and tissues specialize in structure and function

Process through which a plant becomes independent following emergence through soil, development of leaf lamina, and formation of adventitious roots.

Process through which a plant becomes independent following emergence through soil, development of leaf lamina, and formation of adventitious roots.

Composed of profusely branched roots with many lateral rootlets but with no main or tap root development.

A joint on a stem where shoots, leaves and flowers arise.

An indeterminate inflorescence whose primary axis bears branches of pedicelled flowers.

A plant that lives three or more years.

The process in which plants use light energy to make sugars and other organic food molecules from carbon dioxide and water.

using plant tissue to generate new plants.

A simple, indeterminate inflorescence with pedicelled flowers.

(sod grass) - horizontally spreading grass that may have rhizomes or stolons.

An unbranched, indeterminate iflorescence with sessile flowers.

a small spike in grasses, the subunit of the inflorescence.

a small spike in grasses, the subunit of the inflorescence.

Lowest portion of a stem closest to ground that stores carbohydrate and protein reserves critical for regrowth in grasses

Elongated tillers in which the apical meristem remains vegetative, i.e., it does not develop inflorescence primordia.

A shoot that bends to the ground or that grows horizontally above the ground and produces roots and shoots at the nodes.

growth stage where a plant produces new leaf tissue.

Subjection of plants to low temperature in order to hasten plant flowering.
