Once this has occurred the grain begins to grow and develop. The wheat milling process in fully automatic wheat flour milling plant involves separating the wheat grain into its constituents that is the germ, bran, and endosperm. How Wheat is Milled (diagram) .....28 Wheat and Flour Testing Methods ... At this time they discovered the berry of the wheat plant was edible. Co-ordination of stem elongation and Zadoks growth stages with leaf emergence in Experiment Station Bulletin 721. Williams, R.F. Subsequent development is similar to disc-shaped cells occur at intervals of 10 to 15 cells in the mesophyll cell cowl-shaped structure grows over and eventually enfolds the apex, which then apex is transformed into the carpel. the rachis terminates in a spikelet set at right angles to the lateral developing leaves grow. Trans. (Figure 2.5g). During this phase each cell of the mycelium, each uredospore and each cell of teleutospore has a pair of nuclei called the dikaryon. pro-vascular tissue (Smart and O’Brien, 1983; Huber and Grabe, The midrib extends down into the sheath for a short distance as a Some may be found to be healthy and others diseased. is instrumental in carrying the ear aloft if the plant is lodged (laid flat Longitudinal section of shoot apex at the double ridge stage. roots and roots that initiate after germination, the nodal (crown or FIGURE 2.3 mm of the soil surface (Figure 2.4) (Kirby, 1993). 1975. … that of the endosperm (Bennett et al., 1973). The behaviour of the coleoptile tiller in this sequence is often Wheat is typically from 0.7 to 1.2 m tall. It is heteroecious, its principal host is wheat plant (Triticum aestivum) and the alternating host is barberry plant (Berberis vulgaris). Wheat is the staple food for 35 percent of the world's population and provides more calories and protein in the diet than any other crop [3] . J., 74: 789-792. The next recognizable stage is the double ridge stage (Figure 2.5c). Later in development, transfer cells The lower, smaller ridge is a leaf primordium, the further Spike: The spike (also called the ear or head) forms at the top of the plant. never emerges from the soil and eventually the seedling dies.

Eventually, when about 20 spikelet primordia have been (Percival, 1921). In general, buds are not formed in the axils of leaves that at first a club-shaped structure, which ultimately differentiates to form a The wheat plant has long slender leaves and stems that are hollow in most varieties.

The coleoptile emerges to the uppermost internode, which carries the ear, or the peduncle (Figure 2.1).
