Opis:
In the present study, the morphological features of 20 taxa of the family Solanaceae were studied. The Solanaceae, or nightshades, are an economically important family of flowering plants. The family ranges from herbs to trees, and includes a number of important agricultural crops, medicinal plants, spices, weeds, and ornamentals. Many members of the family contain potent alkaloids, and some are highly toxic, but many cultures eat nightshades, in some cases as staple foods. The present observation shows that majority of Solanaceae members almost the same morphological features that of the family.

Opis:
A total of 47 localities of Baeothryon alpinum, hosting population of more than 100 000 shoots, were recorded in the lowland part of Poland during field surveys in the years 2003-2009. Among them were 25 populations discovered for the first time. Out of 57 sites of the species known from literature and unpublished (including herbarium) sources, 35 were not confirmed during the survey, 27 of them being definitely extinct. B. alpinum shows a clear pattern of distribution in Poland, with three main areas of occurrence: 1) the north-easternmost Poland (Lithuanian Lake District with the adjacent parts of the Masurian Lake District and the upper Biebrza river valley in North Podlasie Lowlands), which is part of the species boreal main range; 2) scattered localities in north-western Poland; 3) mountain mires at higher altitudes in the Sudetes and Tatra mountains and the adjacent part of southern Poland. The main aggregation of localities is found in Augustów Forest (including the Sejny Lakeland and Wigry National Park), and in the Góry Sudawskie region with adjacent areas. The biggest Polish population in the "Kobyla Biel" fen near Augustów consisted of several dozens of thousands of shoots. The Lithuanian Lake District is an area of general importance for the conservation of B. alpinum in Poland. The species is threatened, first of all, due to secondary succession (mires overgrowing with shrubs, trees and reed) and requires conservation measures as well as establishing nature reserves in places where it occurs. The degree that B. alpinum decreases in number is strikingly different in particular regions of Poland - it has lost most of its localities in north-western Poland and in Masurian Lake District, while in the Lithuanian Lake District and the upper Biebrza valley there are minor losses only. Depending on the region (from the west to the east and from the south-west to the north-east), the species should be given extinct or critically endangered (regions of north-western and southern Poland), endangered (Masurian Lake District), vulnerable (North Podlasie Lowlands) and near threatened (Lithuanian lake District) status. Although the disappearance of the populations beyond the species main range is a common phenomenon, the presented pattern is man-related and connected with differences in land management.

Opis:
The paper provides a review of the studies focusing on the impact of plant trimming and pruning (especially in tree rows) and tree crown formation (in orchards and urban greenery) on the bionomy and number of aphids and some other hemipterans. The fresh, succulent shoots which appear after any trimming and pruning provide aphids with "eternal spring" conditions, i.e. the availability of young leaves and shoots preferred by aphids as a source of nutrition. The majority of aphid species acquiring nutrition from leaves feed on the top shoots. People shape garden greenery, forming beautiful, decorative tree crowns. Some shoots in orchards are regularly cut off; sometimes even apple trees are planted in rows. Instead of building traditional fences, hedges are planted and regularly trimmed. Trimmed plants have fresh, succulent shoots, which are an attractive source of nutrition for many aphids. Large numbers of aphids inhabit these rejuvenated plants. Cutting and trimming of plants often have an impact not only on the number of aphids, but also on their bionomy.

Opis:
The characteristics of Polish rural agglomerations indicate that only 32% of these areas are villages typified by compact buildings where the use of a collective sewage system is economically justified. In other areas, it is necessary to apply solutions that allow for the sewage utilization in place of their creation and safe discharge into the environment, e.g. in the form of home systems based on biological processes, e.g. in soil-plant systems. The purpose of the work was to determine the soil-plant efficiency of wastewater treatment with the use of so-called energy plants. The experiment was conducted in 2012–2014 in lysimeters at a depth of 130 cm and 100 cm in diameter. These were submerged in the ground, filled with sand clay and equipped with installations enabling the drainage of gravity water in the form of lysimeter effluents. Two species of plants were used: Miscanthu giganteus and Sida hermaphrodita (L.) Rusby. They were irrigated with pretreated domestic sewage (variant I – 1200 mm year−1 and variant II – 1600 mm year−1). For irrigation, sewage from a group of buildings inhabited by six families was used. Raw domestic sewage was discharged into the tank, consisting of four chambers, which constituted a relatively good level of pre-cleaning. For the irrigation of plants in the experiment, pre-treated sewage was used. In order to determine the effectiveness of wastewater treatment in the soil-plant environment, the concentrations of the following components were determined in the effluents: TSS, BOD5, COD, Ntot. The quantities of pollutants contained in the sewage were characterized by considerable variability, especially in relation to COD (390.6– 1583.0 mg O2 dm−3) and Ntot (47.0–250.2 mg N dm−3).

Lipid peroxidation, which is a natural and essential process, can occur in a non-enzymatic and/or enzymatic way in plant cells. Some of its products have cytotoxic effects on cells, but others function as plant effectors. The lipid peroxidation in plants exposed to heavy metal stress depends on the metal, plant organ, plant species and its genotype.

Opis:
Productivity of plants is determined by multiple factors that directly affect one another, therefore yield variability may be high and difficult to predict. Most often, however, a lower crop yield is achieved in the notillage system than in the ploughing system. An exact field experiment was undertaken to determine the yield and chemical composition of pea seeds sown under conditions of: 1) conventional tillage – CT (shallow ploughing and harrowing after the harvest of previous crop, pre-winter ploughing in winter); 2) reduced tillage – RT (stubble cultivator after the harvest of previous crop); and 3) herbicide tillage – HT (only glyphosate after the harvest of previous crop). A cultivation unit was applied on all plots in the springtime. Pea seed yield was higher by 14.1% in the CT than in the RT system and by 50.5% than in the HT system. The CT system was increasing the plant number m–2, number of pods and seeds m–2, seed mass per plant, and 1000 seeds mass, compared to the other systems. Protein content of seeds was at a similar level in all analyzed tillage systems, but was affected by the study year. In turn, the mineral composition of seeds was determined by both tillage system and study year. The seeds harvested from CT plots contained more phosphorus and iron, those from RT plots – more calcium and zinc, whereas those from HT plots – more phytate-P, potassium, magnesium, and copper, compared to the seeds from the other plots

Opis:
A comparative morphological and anatomical study on the petioles and lamina of 22 taxa (species, subspecies and cultivars) of the genus Philodendron (subgenera Meconostigma, Pteromischum and Philodendron) has been made in order to investigate interspecific differences which may be useful in species identification. All species have bifacial leaves with petioles, amphistomatic with a strongly reduced density of stomata on the adaxial leaf surface. The species differ in the size and shape of their epidermal cells, the distribution and types of stomata and cuticle ornamentation in the lamina, thickness of epicuticular layer, presence or absence of hypodermis, structure of spongy mesophyll, thickness of palisade and spongy mesophyll layers, as well as types of raphides, and in the structure and forms of petioles. A combination of these characters may be useful in species identification. This study shows that there is some variation in petiole and leaf morphological and anatomical characters among the 22 taxa of Philodendron. However, many characters are present in all of them and may be typical of the genus. The study revealed several detailed interesting epidermal and anatomical features that have not previously been reported in the genus.

Opis:
Lachenalia is a poorly known genus of ornamental bulbous plants from South Africa with a huge floricultural potential. The paper discusses in vivo multiplication with leaf cuttings of Lachenalia cv. ‘Namakwa’, ‘Romaud’, ‘Ronina’ and ‘Rupert’. Mature leaves were collected from non-flowering donor plants. Each leaf was halved to make proximal and distal leaf cuttings. ‘Ronina’ distal leaf cuttings produced the lowest number of bulblets (5.7 per cutting), while ‘Namakwa’ proximal leaf cuttings turned out the most productive (10.5 bulblets per cutting). The bulblets produced by cv. ‘Namakwa’ distal leaf cuttings were the lightest (0.3 g per bulblet), and those formed on cv. ‘Ronina’ proximal leaf cuttings were the heaviest (0.9 g per bulblet). In general, the weight of individual bulblets ranged from 0.1 to 1.2 g. Irrespective of the cutting type, the leaves of cv. ‘Namakwa’ produced the greatest number of bulblets, and the leaves of ‘Ronina’ yielded the heaviest bulblets. With no dependence on their genotype, proximal leaf cuttings were advantageous in terms of total number of generated bulblets and their quality (weight, diameter).

This study was conducted to determine the mineral contents and some nutritional properties of Trachystemon orientalis L. growing in the Central Black Sea Region, Turkey, and that is consumed as vegetable. Surveys and field studies were started during the spring semester of 2011 (April–May) and they were collected from Samsun and Ordu, where they are intense. In the study, it is was observed that pH, dry matter, content of ash, N, protein, vitamin C, macro- and microelements examined in Trachystemon orientalis varied considerably. The pH, dry matter, ash, N, protein and C content of the plants ranged from 6.61 to 6.88, 13.0 to 22.1%, 9.2 to 17.0%, 2.3 to 3.3%, 14.1 to 20.3 % and 0.12 to 39.03 mg/100g, respectively. Mineral analysis showed that Trachystemon orientalis contained considerably high amounts of potassium (3883.8 to 5791.4 mg/100g), phosphorus (339.7 to 540.9 mg/100 g), calcium (159.4 to 432.4 mg/100g), magnesium (108.0 to 176.4 mg/100 g), iron (10.7 to 63.1 mg/100 g), sodium (22.1 to 66.3 mg/100g), copper (0.6 to 1.5 mg/100 g), manganese (1.5 to 3.6 mg/100g) and zinc (2.3 to 7.6 mg/100g). Mineral compositions of the plants varied significantly depending on the genotypes. T. orientalis was determined as abundant in contents of vitamin C, minerals and protein.

In order to develop an efficient micropropagation system, it is essential to establish the appropriate concentration of growth regulators for seed germination, shoot formation and rooting. Nodal segments from in vitro obtained seedlings of Gentiana lutea L. were cultured in vitro in Murashige and Skoog’s medium supplemented with BAP, Thidiazuron and Zeatin (0.5, 1.0 and 2.0 mg L−1). A maximum number of shoots with the highest height was recorded at 2.0 mg L−1 BAP. For further optimization of the process, we used nutrient media containing BAP and Zeatin with a combination of low concentration of Indoleacetic acid. MS medium containing 2.0 mg L−1 Zeatin and 0.2 mg L−1 IAA resulted in maximum numbers of shoots 94.3) with shoot height 2.5 cm. The multiple plants were successfully ex vitro acclimatized with 65% survival. The presence of growth regulators (2.0 mg L−1 Zeatin and 0.2 mg L−1 IAA) in the nutrient media resulted in an effective antioxidant activity in G. Lutea determined by the low molecular antioxidant metabolites such as phenols and flavonoids and activities of antioxidant enzymes – catalase, ascorbate peroxidase, guaiacol peroxidase, and superoxide dismutase. The described protocol allows the establishment of numerous micropropaged plants of rare and endangered G. lutea.

Opis:
A study was conducted to investigate the ability of arbuscular mycorrhizal fungi (AMF) in enhancing the growth and control of a root rot caused by different isolates of Fusarium oxysporum in sweet pepper seedlings. The plants were grown in plastic pots filled with sterilized horticultural soils. There were four treatments applied as follows: Fo (seedlings infected with fungus), M (seedlings inoculated with mycorrhizal fungi), Fo + M (seedlings inoculated with mycorrhiza and infected with fungus) and control. A randomized experiment was used and the growth, disease index, and photosynthetic activity of the plants were measured after 4 weeks. The investigations showed that the mycorrhizal inoculation had a protective effect on the F. oxysporum-infected pepper seedlings. The plants were characterized by a higher growth rate and a lower disease index than those growing only in the presence of the pathogenic fungus. The roots inoculated with mycorrhizal fungi were better developed than those infected only with F. oxysporum. The mycorrhiza contributed to an increase in the photosynthetic activity of the pepper seedlings.

Test were performed by poisoning the culture media. The percentage of inhibition of the growth of four- and eight-day-old colonies on the medium with preparations in the control colonies was a measure of activity of the preparations. Moreover, the microscopic observations of morphological structures of fungus were conducted. Within chemical compounds trifloxystrobin, tiophanate methyl and mancozeb pointed to be the most effective. The effectiveness of Beta-chikol and Biosept Active in limiting B. strasseri colony growth was higher than the efficiency of Bioczos.

Opis:
The experiment studied the effect of various mulching terms of ‘Foxtrot’ tulips with wheat straw in combination with spraying of plantations with herbicides using various doses and different amounts of working liquid. The mulch was laid out just after planting and after the soil had frozen. The experiment included combinations, in which the mulch was left until the end of the growing season or removed in spring. Spraying with single (linuron 675 g·ha–1 + lenacyl 1000 g·ha–1) or double herbicide dose (linuron 1350 g·ha–1 + lenacyl 2000 g·ha–1) was made before covering the soil with mulch and also on mulch – two weeks after planting the bulbs, or in the spring after thawing the soil. Volumes of 300 dm3 and 600 dm3 of working liquid were used for spraying. Tulips covered with mulch bloomed 2–3 days later and formed longer shoots as compared to non-mulched ones. The highest yield of marketable bulbs and the first-selection ones was obtained from tulips mulched immediately after planting and sprayed 2 weeks later with herbicides used in a single dose of 600 dm3 of a working liquid. Mulching of tulips after soil freezing and removal of mulch in spring adversely affects the number and weight of commercial bulbs. The lowest yield was obtained in combinations, in which the mulch was not used. The use of additional nitrogen fertilization before laying out the mulch did not affect the yield of tulips. Herbicides can be used both before mulching and after covering the plantation with mulch. It is not necessary to increase the dose of the agent and the amount of water.
