Cereal canopy characteristics as the stress indicators
Original language description
Small-plot field experiments with winter wheat and spring barley were carried out at two locations differing in soil and climatic conditions during 2005-2007. Variants with contrast stand structure were investigated during stem elongation. Analyses involved determination of individual plants and tillers, above-ground biomass and nitrogen uptake. Plant responses to the level of sources 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. Intra-plant competition increased values of the CV of the shoot weight. During stem elongation, the differentiation of tillers into two groups, vegetative and potentially productive, take place. This was accelerated by the lack of nitrogen or by a higher plant density. The separation of shoots into two groups enabled to determine the proportion of the potentially productive biomass in the total above-gro
