    Abstract: Drought stress is one of the many factors that lead to decreased yield in both quality and quantity. One method to improve plant resistance to this stress is application of biostimulants. The most widely used biostimulants are protein hydrolysates, containing sea algae extract and humus compounds. In the present study, the influence of the amino acids as well as combination of amino acids with Ascophyllum nodosum filtrate on broccoli (Brassica oleracea var. italica) plants cvs. ‘Agassi’ and ‘Tiburon’ was investigated. The plants were watered with Ascophyllum nodosum filtrate three days before planting and sprayed three times with amino acids two, four and six weeks after planting. The present results show that biostimulants have a significant effect on both gas exchange and transpiration rate both prior to the application of stress, under drought stress and after re-watering. Biostimulant treatment led to an increase of drought tolerance in both studied cultivars but the final effect depended on cultivar. ‘Tiburon’ cultivar turned out to be more tolerant to drought stress than ‘Agassi’. The application of biostimulants resulted in an increase of photosynthetic rate, stomatal conductance, internal CO2 concentration and transpiration rate in ‘Agassi’ cultivar under drought stress. This effect was not observed in ‘Tiburon’. The chlorophyll content was higher under drought stress as compared to the value prior to stress in both cultivars.

    Abstract: High quality planting material is the basis for good strawberry yields. The productivity of strawberry mother plants depends on many factors, but there is little published work on the effects of type and initial size of mother plants on the quality of daughter plants. In the presented study, strawberry mother plants (cultivar ‘Elsanta’) were grown in an unheated tunnel in plastic pots filled with peat-based substrate (5 dm 〈 sup 〉 3 〈 /sup 〉 ). The aim of the study was to evaluate the influence of type (fresh-dug plants and frigo) and initial size (A and A+ plants) of strawberry mother plants on selected parameters of daughter plants (crown diameter, fresh and dry weight as well as number and area of leaves). The study was carried out in 2006 and 2007. Strawberry mother plants were planted in the second decade of April and daughter plants were detached in the second decade of August. All measurements were performed on the second daughter plant on the mother plant runner. Statistical analysis showed that type of mother plants had a significant effect on number of leaves in daughter plants. Daughter plants obtained from mother plants established from fresh-dug plants had the highest number of leaves. The initial size of mother plants significantly influenced the fresh and dry weight of daughter plants. Smaller mother plants (“A-size”) produced daughter plants with higher fresh and dry weight. The results obtained in the second year of the study were affected by high incidence of powdery mildew.

    Abstract: Przeprowadzono analizę wpływu temperatury na wielkość i jakość plonu brokuła, Badaniami objęto trzy odmiany: Cruiser, Skiff i Fiesta, Rozsadę posadzono w pięciu terminach w latach 1995 i 1996, w dziewięciu w roku 1997 oraz w ośmiu terminach w roku 1998, Długość okresu od sadzenia do pierwszego zbioru w każdym z 27 terminów uprawy podzielono na trzy równe odcinki, wyznaczając w ten sposób trzy okresy wzrostu, Jako czwarty okres wzrostu wyznaczono okres zbiorów, Temperaturę w przedziale od 0°C do 40°C podzielono na pięciostopniowe zakresy, następnie obliczono korelacje między liczbą godzin temperatury w poszczególnych pięciostopniowych zakresach, występującą w czterech okresach wzrostu roślin, a wielkością plonu ogólnego oraz udziałem róż z nierówną powierzchnią, o niewyrównanych pąkach i luźnych. Największy wpływ na wielkość plonu miał czas trwania temperatury w zakresie 15-25°C w pierwszym okresie po posadzeniu roślin oraz w okresie poprzedzającym zbiór. Dłuższy okres występowania temperatury powyżej 20°C w okresie zbiorów sprzyjał uzyskaniu niższego plonu. Im dłuższy był czas występowania temperatury w granicach 20-25°C w okresie poprzedzającym zbiór oraz temperatury w zakresie 5-15°C w czasie zbioru róż, tym mniejszy był udział róż z nierówną powierzchnią, Występowanie przez dłuższy czas temperatury powyżej 20°C w okresie zbiorów sprzyjało rozluźnianiu się róż.

    Abstract: The white button mushroom Agaricus bisporus (Lange) Imbach is an edible mushroom of top economic significance. In recent years the consumption of fruiting bodies of this species has been increasing in Poland. The article characterises the chemical composition and health-promoting properties of white button mushrooms. The latest scientific research confirms that the fruiting bodies of white button mushroom have high nutritional value. They contain good quality proteins, necessary unsaturated fatty acids, fibre, some vitamins and numerous minerals. Apart from that, white button mushroom fruiting bodies contain a wide range of bioactive substances, which have a positive influence on health, such as polysaccharides, glyco-proteins, tocopherols, polyphenols and other antioxidants, e.g. ergothioneine. Apart from the antioxidant properties, the white button mushroom also has anti-inflammatory, antimicrobial, antifungal, anticancer, immunomodulatory, hepatoprotective and anti-atherosclerotic activities.

    Abstract: Biostimulants are commonly used in horticulture, primarily to increase yield quantity and quality, as well as plant tolerance to stress. The purpose of the study was to determine the effect of amino acid-based biostimulants and amino acids in combination with Ascophyllum nodosum filtrate, applied during the growing season on the phenolic content in broccoli heads both after harvest and after long storage in a cold store. The seedlings were planted in mid-July, and heads were harvested from September to October in each year of the study. Ascophyllum nodosum filtrate at a concentration of 1% was used during seedling production. The plants were watered with biostimulants twice, in the fourth and fifth week after sowing. They were also sprayed with amino acid-based biostimulants (1.5 dm3 ha-1) three times, i.e. after the second, fourth and sixth week after planting. The biostimulants were not used in the control treatment. After harvest, the heads were stored for three weeks in a cold store at 1-2°C and 95% RH. Chemical analyses of total phenolic, caffeic, ferulic and sinapic acids, and of quercetin and kaempferol were carried out on samples of fresh broccoli and after the first, second and third week of storage. It was found that the application of biostimulants resulted in a significant increase in the total phenolic content, sinapic acid content, as well as quercetin content. Both in the control treatment and in the plants treated with the biostimulants, the concentration of all the tested phenolic compounds increased with the duration of storage.

    Walter de Gruyter GmbH ; 2018

    Abstract: There are about 40 species in the Pleurotus genus, including those with high economic significance, i.e. P. ostreatus and P. pulmonarius . The fruiting bodies of oyster mushrooms are of high nutritional and health-promoting value. In addition, many species belonging to the Pleurotus genus have been used as sources of substances with documented medicinal properties, such as high-molecular weight bioactive compounds (polysaccharides, peptides and proteins) and low-molecular weight compounds (terpenoids, fatty acid esters and polyphenols). The bioactive substances contained in the mycelium and fruiting bodies of Pleurotus species exhibit immunostimulatory, anti-neoplastic, anti-diabetic, anti-atherosclerotic, anti-inflammatory, antibacterial and anti-oxidative properties. Their multidirectional positive influence on the human organism is the result of interaction of bioactive substances. Extracts from individual Pleurotus species can be used for the production of dietary supplements increasing the organism’s immunity. They are also used for the production of cosmetics. They can be added to functional foods as probiotics, or used as natural preservatives or ingredients of special foodstuffs for patients with specific diseases.
