Abstract
The content of reducing sugars, soluble pectins, protopectins and free and bound calcium in above-ground parts of field pea (Pisum arvense L.) during budding and flowering in field conditions was determined. In this experiment different mineral fertilization and Afalon (linuron) were used. Afalon was applied to the soil in weed control dose (1 kg/ha A.S.). The significant influence of linuron and the level of fertilization on the content of determined components in investigated material was not corroborated. The content of pectic substances, first of all, was dependend on phase of vegetation. The differences in the content of calcium were related to distribution in above-ground parts of investigated plants. The tendency to reduction of the content of reducing sugars after application of linuron was observed only during budding of field pea. The received resultes show that linuron used in weed control doses has not evoked unprofitable changes in the content of investigated components of cell wall which they could the significance in the growth and development and in some immunity reactions of plants.
