Study Notes

Wheat Plant Structure

The wheat plant has a reproductive stage where the flower develops after emerging from a stem, known as heading.
The wheat flower is self-pollinating and the flowerhead, or inflorescence, is made up of a cluster of flowers called spikelets.
A spikelet consists of multiple florets, each containing a glume, lemma, palea, stamens, and an ovary.
After pollination, the grain begins to ripen and mature.

Wheat Grain

The wheat seed is classified as a grain or kernel and is the fruit of the wheat plant.
The wheat grain is made up of various components, including the outer husks, glume, lemma, palea, stamens, and ovary.

Wheat Production Systems

Two factors that influence the flowering of wheat are [to be identified by the student].
Two production systems used to grow wheat are [to be identified by the student].
The Aboriginal grain belt and the contemporary wheat belt are located in different areas, as shown in Figure 7.8.

Comparison of Wheat and Native Millet

Winter wheats are grazed during the winter months, while native millet can provide feed for livestock into the dry season.
Perennial crops like native millet have advantages in a mixed farming enterprise, such as designing a calendar of operations that maximizes grazing potential.

Experiment: Plant Density and Wheat Growth

The experiment aims to compare the effect of plant density on wheat growth, including the number of tillers and plant height.
The results show a relationship between planting density and the number of tillers or height, with [to be interpreted by the student].
The experiment can be used to design a value-added product based on native millet as an Aboriginal food ingredient.
