Abstract
The intensity of the foliar respiration at the parasitized plants depends on several factors. In the same circumstances, under the same environmental conditions, different species have different respiratory intensities. The respiratory process in rye plants was observed from the beginning until the end of the growth period of rye and of Claviceps purpurea parasite as well. During this period the foliar respiration presents high variations from one stage to another. The presence of the parasite determines important changes related to the predominant alkaloid type of the Claviceps purpurea strains, which parasite the rye. The intensity of the respiratory process is also influenced by the stages of fungus’ life.
