Two Phases

The content of reducing sugars in field pea leaves and stems (<i>Pisum arvense</i> L.) during two phases of vegetation (budding and flowering) in field conditions was determined. In this experiment two levels of mineral fertilization and simazine (Gesatop-50) and prometryne (Gesagard-50) were used.

Pectic Substances

The content of reducing sugars, soluble pectins, protopectins and free and bound calcium in above-ground parts of field pea (<i>Pisum arvense</i> 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.

The content of pectic substances (soluble pectins and fractions of protopectins in field pea (<i>Pisum arvense</i> L.) leaves during vegetation in field conditions were determined. The influence of linuron (Afalon) and different mineral fertilization on the content of various fractions of pectic substances and rate of protopectins methylation was investigated.

Pectic Substances

The content of pectic substances (soluble pectins and fraction of protopectins) and calcium (free and bound) in field pea (<i>Pisum arvense</i> 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.

Greenhouse experiments with maize were carried out to see if the reported infertility of some subsoils could be improved with mineral fertilization and efficient watering. It was shown that the Nipe soil series (Typic Acrorthox; clayey, oxidic, isohyperthermic) exposed subsoil was as productive as the Carreras series (Aquic Tropohumult; clayey, kaolinitic, isohyperthermic) surface soil when N, K, micronutrients and 600 ppm P were added and the pots were watered by means of wicks. Carreras subsoil, when limed and fertilized with N, K, 300 ppm P, 100 ppm Mg and 36 ppm Zn produced as well as Carreras surface soil, even though it contained only about one-third as much organic matter. A comparison among eight surface and subsoils showed that yields on limed, liberally fertilized, well-watered Los Guineos series (Epiaquic Humoxic Tropohumult; clayey, kaolinitic, isothermic) surface soil, Carreras surface soil, Piña series (Psammentic Haplorthox; sandy, isohyperthermic) surface soil, Los Guineos subsoil, Piña subsoil and Catalina series (Tropeptic Haplorthox; clayey, oxidic, isohyperthermic) surface soil were not significantly different. However, the yield on the least productive of two Catalina subsoils was only 64 percent of the yield on the Los Guineos surface soil. But with the addition of Zn and slightly over 1,000 ppm P, greenhouse pot yields on the two soils were essentially the same. Field experiments will be necessary to determine optimum P rates under field conditions. It was concluded that the productivity in greenhouse pots of surface and subsoils of the Ultisols and Oxisols studied can all be brought to the same high level, provided adequate mineral fertilization (including Zn and high P rates), lime and water management are used.

A study was curried out on the influence of mineral fertilization on the chemical composition of the cell walls of culms of wheat, barley, rye, and oats at the ear-forming stage. The content of reducing sugars, protein, pectin substances, hemicellulose, lignin, ash, and α-cellulose has been determined as well as the distribution of some of the micro- and macroelements in the lower and the upper parts of culm.
