A wide diversity of topics, ranging from the fine structure of cells to the gross morphology of the shoot, will be discussed in this chapter, providing a brief summary of the large amount of accumulated knowledge that exists on the botany of wheat. The techniques employed include those of physics, chemistry, physiology, psychology, genetics, and ecology, and so constitute a broad training in biology that may be useful and acceptable in other fields. trailer <<377E8232E1D34DF187176F31A14DF0C0>]>> startxref 0 %%EOF 1006 0 obj <>stream ��� � �~�W endstream endobj 961 0 obj <>/Metadata 958 0 R/Pages 957 0 R/StructTreeRoot 62 0 R/Type/Catalog>> endobj 962 0 obj <>/ProcSet[/PDF/Text]/ExtGState<>>>/Type/Page>> endobj 963 0 obj <> endobj 964 0 obj <>stream 0000014167 00000 n 0000045865 00000 n 935 65 0000189070 00000 n The vegetative state of the plant is characterized by tillers bearing axillary leafy culms. The many species of wheat together make up the genus Triticum; the most widely grown is common wheat (T. aestivum).The archaeological record suggests that wheat was first cultivated in the regions of the Fertile Crescent around 9600 BCE.
