This study was aimed at evaluating the effect of sublethal doses of glyphosate on physiological parameters of a common ornamental plant Mexican marigold (Tagetes erecta). The herbicide was applied in the following doses: 720 g ⋅ ha–1 (standard field dose), 144 g ⋅ ha–1, 28.8 g ⋅ ha–1, and 14.4 g ⋅ ha–1, in the form of a spraying treatment of plants in a specialist spraying chamber. The net assimilation rate and leaf greenness index were then determined. Herbicide application in the sublethal doses, i.e. below 720 g ⋅ ha–1, caused disorders in both analyzed physiological parameters of plants. The glyphosate dose of 144 g ⋅ ha–1 elicited transient disorders in the leaf greenness index. In turn, the use of the lower doses (28.8 g ⋅ ha–1 and 14.4 g ⋅ ha–1) caused a short-term increase in the net photosynthesis rate in the plants which was accompanied by a decreased value of the leaf greenness index. Study results demonstrated the effect of sublethal doses of glyphosate as a stress factor in parameters associated with the process of photosynthesis in plants.

The research was conducted with a view to establishing physiological parameters of the silver fir (Abies alba Mill.) with regard to germination energy, absolute germination and genetic overload produced by silver fir populations. The intention was to identify significant variability within populations and subpopulations, or rather within the two combined, and to give recommendations on the usage and usability of seeds from specific populations. The results form a basis for establishing silver fir genetic overload within five fir populations of central Bosnia and Herzegovina. The results of research on the characteristics such as absolute seed weight, germination energy and absolute germination are within a scope of previous studies. The studied physiological characteristics of silver fir seeds in the central Bosnia area showed distinct individual and inter-population variability when compared to variability of the subpopulations analyzed. The inclusion of non-physiological data (height, DBH, age and the presence of mistletoe) concerning sampled trees proved to be effective new quality of research. No correlation was found between DBH and seed physiological characteristics but increased tree height had a positive effect on seed quality in terms of absolute germination and growth, proportional to tree height. This in turn shows that seeds should be collected only from trees of above average height, because they are less genetically overloaded. The characteristics of healthy but ungerminated seeds from less tall trees displayed lower parameter values, also indicating that seeds should be collected from taller than average trees only. The presence of mistletoe had a very interesting effect of increasing rotten seeds percentage, and therefore reducing seed quality. Accordingly, seed collection should be limited to trees not affected by mistletoe, however further research on this aspect is required.

The purpose of this paper was to determine the sunflower (Helianthus annuus L.) reaction to nickel depending on the metal concentration and penetration way, i.e. through roots or leaves. Nickel was introduced into the nutritional solution (intraroot application) at amounts: 0 (control), 35, 100 or 200 μM, while intraleaf application was performed by spraying plants with water (control) or nickel containing solution at the concentration of 5 or 10 μM. Plants treated with nickel intraroot than intraleaf were characterized by a considerably higher metal content in roots and lower in leaves. Independently of the penetration way increasing metal concentrations caused a significant decrease of the parameters of physiological root activity, i.e. the root volume, total and active adsorption surface and 1 cm³ root active surface, in that a greater decrease of the root parameters was shown on intraroot than intraleaf application of the metal. Environment contamination with nickel caused also a chlorophyll concentration decrease in leaves, in that intraleaf nickel application, in contrast to intraroot, resulted in a higher decrease of chlorophyll b than a. Older than younger leaves showed a higher susceptibility to nickel applied intraroot, whereas roots were resistant to nickel applied intraleaf. The content of S-SO₄ in the sunflower depended on the nickel concentration and penetration way – intraleaf nickel application caused significant S-SO₄ increase in leaves and roots, whereas intraroot application resulted in S-SO₄ content increase especially in roots.

Celem pracy było określenie reakcji słonecznika (Helianthuus annuus L.) na nikiel, w zależności od stężenia i drogi wnikania metalu, tj. przez korzeń lub liść. Nikiel wprowadzano do pożywki (aplikacja dokorzeniowa) w ilościach: 0 (kontrola), 35, 100 lub 200 μM, natomiast aplikację dolistną wykonano, opryskując rośliny wodą (kontrola) lub roztworem zawierającym nikiel w stężeniu 5 lub 10 μM. Znacznie wyższą zawartością niklu w korzeniach i niższą w liściach charakteryzowały się rośliny traktowane niklem dokorzeniowo niż dolistnie. Niezależnie od sposobu wnikania, wzrastające stężenia niklu wpłynęły na istotny spadek parametrów fizjologicznej aktywności korzeni, tj. objętości, ogólnej i aktywnej powierzchni adsorpcyjnej oraz powierzchni 1 cm³ , przy czym większy spadek wskaźników korzeni wykazano po dokorzeniowej niż dolistnej aplikacji metalu. Skażenie środowiska niklem powodowało również spadek koncentracji chlorofilu w liściach, przy czym dolistna aplikacja niklu, w przeciwieństwie do aplikacji dokorzeniowej wpłynęła na większy spadek chlorofilu b niż a. Większą wrażliwością na nikiel aplikowany dokorzeniowo mają liście starsze w porównaniu z liściami młodymi, natomiast organami odpornymi na nikiel aplikowany dolistnie są korzenie. Zawartość S-SO₄ w słoneczniku zależała od drogi wnikania i stężenia niklu – aplikacja dolistna wpłynęła wyraźnie na wzrost koncentracji S-SO₄ w liściach i korzeniach, natomiast aplikacja dokorzeniowa na zwiększenie zawartości S-SO₄ szczególnie w korzeniach.

Seasonal changes in the morphometric and physiological parameters of the cockle Cerastoderma glaucum (Bivalvia) from the Baltic Sea (GD), the North Sea (LV), and the Mediterranean Sea (BL) were investigated. The cockles from GD were much smaller than those from other populations due to osmotic stress. The female to male ratios did not differ significantly from 1 : 1. The northern populations (GD, LV) had a monocyclic reproductive pattern, whereas the southern population (BL) seemed to reproduce throughout the year. Seasonal changes in the contents of biochemical components appeared to be correlated with changes in trophic conditions and the reproductive cycle. Protein content was the highest in spring for all the populations. The highest lipid contents and lowest carbohydrate contents were noted in GD and BL in spring, while no marked differences were noted among seasons in LV (probably because the data from both sexes were pooled). Respiration rates in GD were the highest among the populations, which could have been due to osmotic stress. High metabolic rates expressed by high respiration rates in GD and LV in spring and autumn could have resulted from gamete development (in spring) and phytoplankton blooms (in spring and autumn).

The effect of the Panax ginseng powder extract on reproduction, growth, renal and liver functions and some blood biochemical indices of Japanese quails were investigated. Panax ginseng powder extract at 2 mg and 4 mg/bird daily increased egg number per hen, average egg weight and hatchability. It slightly improved the efficiency of feed utilization and increased the levels of serum total protein, alkaline phosphatase and aspartate amino transferase (AST). The extract decreased significantly the levels of albumin, total lipids, triacylglycerols, cholesterol and glucose, and had no effect on body weight and the levels of serum bilirubin, urea and creatinine. This suggests that long term studies should be done on many different biochemical and physiological parameters and laboratory animals.
