What are called glumes?

What are called glumes?

In botany, a glume is a bract (leaf-like structure) below a spikelet in the inflorescence (flower cluster) of grasses (Poaceae) or the flowers of sedges (Cyperaceae). Glumes may be similar in form to the lemmas, the bracts at the base of each floret.

What is glumes of wheat?

IN the wheats, as in most grasses, there are empty glumes at the base of each side of the spikelets, and the florets consist of a lemma (flowering glume), palea and flower. One of the more rare abnormalities of flower development in normal varieties is the occurrence of rudimentary florets in the axils of the glumes3.

What is a glume in plants?

Glumes are the maternal plant tissues in the panicle that holds the developing caryopses after pollination.

What is the difference between glume and bract?

As nouns the difference between bract and glume is that bract is (botany) a leaf or leaf-like structure from the axil out of which a stalk of a flower or an inflorescence arises while glume is (botany) a basal, membranous, outer sterile husk or bract in the flowers of grasses (poaceae) and sedges (cyperaceae).

What is Lemma in flower?

Lemma is a phytomorphological term referring to a part of the spikelet. It is the lowermost of two chaff-like bracts enclosing the grass floret. It often bears a long bristle called an awn, and may be similar in form to the glumes—chaffy bracts at the base of each spikelet.

What is Bracteole?

bracteole (plural bracteoles) (botany) A small leaf of leaf-like structure directly subtending a flower or inflorescence whose stalk itself is subtended by a bract. (botany) A bract subtending an individual flower rather than an inflorescence.

What is rice lemma?

The structural units of the rice flower are spikelets and florets. The spikelet is the primary unit of the rice inflorescence and contains a fertile floret and a pair of empty glumes (also called “sterile lemmas” or “rudimentary lemmas”), subtended by a pair of highly reduced glumes called rudimentary glumes.

What is Glume in rice?

The spikelet is the primary unit of the rice inflorescence and contains a fertile floret and a pair of empty glumes (also called “sterile lemmas” or “rudimentary lemmas”), subtended by a pair of highly reduced glumes called rudimentary glumes. Recently, functions of many homeotic genes have been elucidated in rice.
