| Description
| - Historical evolution of approaches used for the assessment of the cereal stand structure development are presented. Weaknesses and strengths of these approaches are discussed that are based on: dividing of cereal yield into yield components and growth analysis; modular concept of plant growth; use of laws of plant population biology in order to explain autoregulation and compensation in stands. The presented methods are assessed with respect to labour intensity and possibilities of utilization of obtained information. Other possibilities of diagnostics of the cereal stand state and structure using a current level of knowledge and new technologies enabling to determine spectral characteristics of the stand by areal sensing are outlined. Based on the character of processes influencing the canpy structure, the growing season of cereals was divided into the three parts: vegetative, including the period from emergence till the end of tillering (BBCH 10 to 29); generative, including the period of stem elongation and heading (BBCH 30 to 59); reproductive, including anthesis, grain formation and maturation (BBCH 60 to 99). In these parts of growing season a detailed evaluation of the development of canopy structure of a winter wheat and spring barley and its spectral characteristics by means of the Normalized Difference Vegetation Index (NDVI) was performed in smallp plot field experiments carried out at two locations of Central and South Moravia within the period of three years (2005to2007). The relationships between the canopy structure characteristic and NDVI were analyzed. To optimize the cereal stand structure, the patterns of canopy development are explained and data (structural and spectral characteristic) necessary for decision making in cereal crop management practices are proposed.
