Botanical Description


Name Brief Description Image
Root The function of roots is to anchor the plant to its substrate and to absorb water and minerals.
Spikelet Spikelet is composed of flowers called florets. The number of florets in a spikelet may vary from 1-5. The florets in each spikelet are enclosed by two glumes.
Awn These are coarse hair-like protrusions on a spike. They extend from the tip of lemmas and sometimes to a small extent on the sterile glumes. Awns photosynthesise when green.
Earhead
Tillers Tillers, which have the same basic structure as the main shoot, arise from the axils of the basal leaves. At anthesis, only some of the tillers that have developed survive to produce an ear. Others die and may be difficult to find in the mature plant
Flag Leaf The flag leaf is the last leaf to emerge before the head
Leaf Sheath It is the basal part of the leaf. It encircles the culm (stem) and provides the growing point and axillary buds from the weather and some support to stem.
Florets The outer covering of a floret is made up of a lemma and a palea. The lemma enfolds the pale a near their attachment point. If an awn is present, it is attached to the lemma.
Stem The stem of wheat plant is round or cylindrical. In most varieties of the bread wheat, the stems are hollow, except at the nodes , re they are solid, but in a few varieties of Macaroni wheats, the internodes are completely filled with soft pith.
Ear The flowering portion of the wheat plant is called ear or head, but in botanical language it is a spike. Spikelets are systematically arranged and are distributed along a common axis. The central zigzag axis is the rachis. The spikelets are borne on alternate sides of the rachis which gives it a zigzag appearance.
Leaf Leaf comprises the sheath, wrapping around the subtending leaf, and a lamina (blade). At the junction of the sheath and lamina, there is a membranous structure, the ligule, and a pair of small, hairy projections, the auricles. The base of the leaves on the culm is thickened to form a hard knot or pulvinus.
Auricle These are the lobes of the leaf blade which extend downward on each side at the junction of the blade and sheath. These are horn-like or claw-like appendages projecting from the collar of the leaf.
