Określono możliwości stosowania okrzemek jako bionawozu nowej generacji w uprawie wierzby wiciowej w warunkach zredukowanego nawożenia syntetycznego i sprawdzono potencjał użyźniania roślin poprzez dolistną aplikację Navicula sp. Wpływ bionawożenia zależał od poziomu wzbogacenia gleby w nutrienty zawarte w syntetycznym nawozie. Pozytywny wpływ okrzemek na wzrost roślin (wysokość, liczba pędów, suma ich długości, plon świeżej i suchej biomasy) był związany ze wzrostem aktywności fizjologicznej (transpiracji, fotosyntezy, przewodnictwa szparkowego, stabilności cytomembran, zawartości chlorofilu w liściach), a także aktywności enzymatycznej (fosfatazy kwaśnej i alkalicznej, RNaz oraz dehydrogenaz). Dolistna aplikacja okrzemek zwiększyła zawartość makroelementów w biomasie roślin wierzby (N, P, K) i nie wpłynęła ujemnie na wartości parametrów energetycznych (ciepło spalania w stanie analitycznym, wartość opałowa w stanie roboczym i zawartość popiołu w stanie roboczym). Okrzemki, jako nowy bionawóz w uprawie wierzby energetycznej, umożliwiają zmniejszenie stosowanych dawek nawozów sztucznych.

Willow plants (Salix viminalis L.) were fertilized with a com. synthetic fertilizer (up to 1.0 g/plant) and then with watersuspended diatoms (Navicula sp.) (600 000 cells in 1 mL of water, sonification at 20 Hz for 15 min, foliar application). The use of diatoms resulted in an increase in the quantity of microelements in plants (N, P, K) but did not affect their energetic properties (heat of combustion, calorific value and ash content) in the working state. The diatoms showed perspective potential as a new generation biofertilizer in prodn. of energy willow.

Correlations between the sowing value of primed tomato seeds (mean germination time – MGT, germination uniformity – T75-25) and selected physiological events (total activity of dehydrogenases – TAD, activity of catalase – AC, activity of the cell cycle – ACC, and leakage of electrolytes – LE) were analyzed in order to find useful physiological markers of seed quality. To accomplish this purpose, we analyzed the effects of different environment-friendly priming methods, the levels of seed moisture content (MC), and incubation times during priming on germination properties (MGT, T75-25) in relation to TAD, AC, ACC, and LE. In addition, we evaluated the effects of used seed conditioning methods on the growth and development of plants obtained from these seeds. The results showed positive effects of seed conditioning on the growth and development of plants obtained from these seeds, and that MGT and T75-25 were significantly correlated with TAD, AC, ACC, and LE from the seeds. The correlations between MGT and the physiological parameters were the strongest (r2 = 77.0 - 97.2%). Somewhat lower values of the determination coefficient (r2 = 62.8 - 92.7%) were noted between T75-25 and the physiological events. Therefore, the investigated physiological parameters of seed quality can be used as markers of germinability and sowing value reached by primed tomato seeds.

Information concerning corn plant development within predicted environmental constraints and the possibility of alleviating their negative influence by ecological compounds is limited. Thus the aim of our research was to evaluate the physiological activity, growth, and development of corn plants under the expected climate-change conditions and treated with Biojodis (certificated extract of humus and active iodine; Joda-vita, Lithuania) and Cyanobacteria (a mixture of monocultures of Microcystis aeruginosa MKR 0105 and Anabaena sp. PCC 7120). 'Cyrkon' corn plants (Zea mays L.) were cultivated in several simulated predicted climate conditions, including constant or periodically changing temperature and soil moisture content. During the vegetative season they were treated at three-week intervals using Biojodis at concentrations of 1.0, 2.0, or 3.0%, and Cyanobacteria, and then assessed using growth and physiological parameters. The obtained results showed the corn's different reactions to the applied conditions. Plants that grew at constant or periodically changing different temperatures (0 to 40°C) or in unsatisfactorily (20% m.c.) or excessively (60% m.c.) watered soils, developed slowly in comparison with those growing at 20°C and in optimally moistened media (30% m.c.). Watering, spraying, or watering and spraying of corn plants with Biojodis (1, 2, 3%) and a foliar application of Cyanobacteria increased their growth at optimal or unfavourable temperature and in unsatisfactory or excessively moistened soil. The three times spraying with Biojodis (1 or 2%) and with Cyanobacteria was most promising. The plant development changes related to the used compounds and simulated environmental constraints were associated with the changes in indexes of chlorophyll content in leaves, stability of membranes, gas exchange, and activity of acid or alkaline phosphatase and RNase. The above indicates that foliar and soil application of Biojodis and plant sprayings with Cyanobacteria increased growth of corn cultivated under optimal temperature and soil moisture content and partly restored the harmful effects of artifi cial temperature and water stress on plant development and physiological activity. Biojodis also can increase the iodine content in corn and uptake of nutrients from the soil, and thus decrease environmental pollution.
