Influence of prometryne (Gesagard 50) on pectic substances and calcium contents in the above-ground parts of the field pea (Pisum arvense L.)
The content of pectic substances (soluble pectins and fraction of protopectins) and calcium (free and bound) in field pea (Pisum arvense L.) leaves and stems during budding and flowering in field conditions was determined. In this experiment Gesagard 50 (S. A. - 50% prometryne) was applied to the so...

| Summary: | The content of pectic substances (soluble pectins and fraction of protopectins) and calcium (free and bound) in field pea (Pisum arvense L.) leaves and stems during budding and flowering in field conditions was determined. In this experiment Gesagard 50 (S. A. - 50% prometryne) was applied to the soil in a weed control dose (2 kg/ha). An insignificant decrease of the content of protopectins and total pectins in leaves of the investigated plants (about 3-7% in relation to control) after application of this herbicide was noted, hut analogous changes in all years of the experiment were not observed in field pea stems. The influence of prometryne on the distribution of pectic substances in above-ground parts of the field pea and the degree of protopectins methylation were not corroborated. Neither did the total calcium content in the investigated plants change after application ofthe herbicide. These results show that application of Gesagard 50 in a weed control dose (2 kg/ha) in cultivation of field pea does not evoke changes in the investigated components content which might be of significance in the growth and development of plant cells and immunity reactions of plants. |
