Growth Stages of Wheat Plant

Growth Stages of Wheat Plant

The wheat plant has to pass through the four stages to complete its life cycle. These stages are:

1. Pre-establishment stage

a. Pre-emergence stage: Sprouting of seeds by giving rise to seminal roots and coleoptiles.

b. Emergence stage: Appearance of coleoptiles from germinating seeds above the soil surface.

2. Vegetative stage

a. Seedling stage: The young plants establish larger root systems at this stage. The stage may be further differentiated as one leaf, two leaf, three leaf and four leaf stages.

b. Crown root stage: This coincides with three or four leaf stages in which the apparance of crown roots takes place.

c. Tillering stage: Plant, at this stage, develops crown and starts branching.

d. Jointing stage: This is the stage at which the plants begin elongating when the nodes start developing above the crown node.

3. Reproductive stage

a. Booting stage: This is the stage in which the upper- most leaf swells out into flag holding the spike into it.

b. Heading stage: In this stage the spike starts emerging out from the leaf sheath.

c. Flowering stage: Anthesis of florets and fertilization of ovaries occurs at this stage.

4. Post-anthesis stage

a. Filling: The ovaries, after fertilization is complete, starts elongation and transform into seeds or ovules passing through milk, soft, dough and hard dough stages.

b. Maturity: Colour of the glumes changes and kernels become fairly hard at this stage. Moisture percentage is gradually reduced and the plant can be harvested at this stage. This is the stage of economic importance.
