Cereal canopy charakteristics as the stress indicators

Popis výsledku v původním jazyce

During three years (2005-2007), small-plot field experiments with winter wheat and spring barley were carried out in the Czech Republic at two locations differing in soil and climatic conditions. Variants with contrast stand structure (different seed rates and N rates) were investigated during stem elongation. Analyses involved determination of individual plants and tillers, above-ground biomass and nitrogen uptake. Two types of relationships were observed as reaction to the level of sources and its effect as stress factor - relationships among plants which are more or less of a random nature and intra-plant relationships dependent on the hierarchic structure of plants. Plant responses were reflected in variability of their tillers. A higher inter-plant competition was expressed by lower values of the coefficient of variation (CV) of the plant weight and the number of tillers per plant. On the other hand, intra-plant competition increased values of the CV of the shoot weight. During st
