Opis:
The research was carried out in 2018 at the experimental station of the University of Life Sciences in Poznań. The plants of the strawberry variety Albion were exposed to sub-zero temperatures in the white bud phase and in full bloom. The possibility of mitigating the results of strawberries subjected to thermal stress was investigated using the Terra-Sorb complex biostimulator with a high content of amino acids. The intensity of flowering, the number, weight and area of strawberry leaves, the number of fruits on a bush and their quality parameters such as fruit weight, extract content and firmness were analysed. It was established that the impact of the sub-zero temperature on strawberry shrubs, regardless of the development phase of the plant, the number of inflorescences and healthy flowers was reduced significantly, the number of fruits, their average weight and firmness decreased. The use of the biostimulator on plants exposed to temperatures from -2 to -3 °C contributed to increasing the number of healthy strawberry flowers by several percentage points, the number of fruits per plant and increased their average weight significantly. The extract content in strawberries remained unchanged.

This study evaluated the development of above and under ground parts of strawberry plants cvs. 'Fern' and 'Camarosa1 in a glasshouse using perlite, forest soil, finpeat, peat, finpeat+perlite (1:1) and peat+perlite (1:1) as substrates. The effects of different growing media on development of above and under ground parts of plant were statistically significant. The highest number of primary roots per plant, length of the most developed roots and number of crowns per runner were obtained from perlite, finpeat+perlite and peat medium, respectively, in both cultivars. The runner length, number of runners per plant, leaf area, fresh root weight and dry root weight varied between cultivars according to growth medium. In general peat, finpeat or finpeat+perlite gave the best results in terms of above and under ground parts of plants in both cultivars. Some important properties such as water retention capacity, cation exchangeable capacity, pH, porosity etc. of growing media using in this study were also determined.

Opis:
Strawberries were the fruit that the Modernists and Modernism were very fond of. It thus should not be a surprise that strawberries also feature in Modernist prose texts of Katherine Mansfield. Although they make their appearance only in a couple of stories, and then merely for a brief moment, they should not by any means be treated as mere tiny blots belonging to the background. For when we take a closer look at them it turns out that, as is usually the case with Mansfield’s short stories, there is more to it than meets the eye. Seemingly unimportant, often unnoticed and therefore frequently underestimated, this small, sweet, red and fragrant fruit makes a significant statement in every text it is mentioned.

Opis:
Strawberry plants showing symptoms of leaf spots and petiole lesions were collected from El Qalubya governorate, which is one of the most famous areas that extensively grows strawberry in Egypt. The objectives of this study were to isolate and characterize the causal pathogen of the disease. The isolated pathogen was identified as Paramyrothecium roridum (formerly known as Myrothecium roridum) based on its morphological characteristics and sequencing the partial rDNA internal transcribed spacer (ITS). A pathogenicity test using detached leaf assay revealed that P. roridum is a potential pathogen of strawberry. Symp- toms started as small necrotic areas which expanded rapidly to macerate whole leaflets and petioles. In advanced stages of infection, dark olive green sporodochia were clearly distinguished on the infected tissues. Six strawberry cultivars showed different levels of susceptibility to P. roridum. Florida was the most resistant cultivar while Beauty, Camarosa, Fortuna and Sweet Charlie were susceptible. Festival showed a moderate level of suscep- tibility. An in vitro assay on the effect of the liquid culture filtrate of P. roridum on straw- berry leaves showed that the filtrate caused damage to tissues and clear necrotic symptoms were developed. High performance liquid chromatograph (HPLC) analysis on the filtrate of 10 day old P. roridum culture revealed the presence of various mycotoxins. The two major toxins detected were 8-alpha-hydroxyroridin H and myrothecin A in addition to other tri- chothecenes. Data also revealed the capability of P. roridum to produce polygalacturonase (PG) and cellulase (Cx) enzymes in liquid cultures. The activity of PG was found to be sig- nificantly correlated with the age of the growth culture. This is the first record of P. roridum on strawberry in Egypt.

Opis:
Long term investigations revealed that cultivation of strawberries (Fragaria magna Thuill.) for 10 years continuously in one plot reduces their vitality: the number of the produced runners decreases by 41%, of leaves – by 30%, form only 28% of inflorescence, the yield reduces by 50% in comparison with strawberries grown for two years in a new plot. Evident decline in the vitality and productivity of strawberries was detected during 4th–6th years of cultivation. Unequal reaction of the tested cultivars upon the durability of cultivation was noticed; strawberries of the cultivar ‘Senga Sengana’ reacted slightly, while the ones of the cultivar ‘Nida’ – strongly. It is related with different sensibility of these cultivars towards the disease agents of root rots. It was determined that long-term cultivation of the Fragaria genus plants results in the accumulation of the parasitic fungi propagules in soil: Ascochyta fragaricola, Cercospora fragariae, Fusarium oxysporum, F. solani, Perenospora fragariae, Phytophthora cactorum, Pythium intermedium, P. ultimum, Plasmodiophora brassicae, Sclerotium rolfsii, Verticillium alboatrum. Therefore, cultivation of strawberries in the same plot for longer time increases the phytopathogenic potential of soil, and short interval (1–2 years) between planting has little significance upon it. The second reason for low productivity of strawberries cultivated for a long in one plot is soil tiredness caused by fungi, synthesising and excreting into surrounding toxic secondary metabolites, widespread in the rhizosphere, especially those belonging to the Penicillium genus: P. janthinellum, P. verruculosum var. verrucosum, P. canescens, P. spinulosum.
Wieloletnie badania wykazały, że uprawa truskawki (Fragaria magna Thuill.) na jednym polu przez 10 lat spowodowała zahamowanie ich wzrostu i rozwoju. Uprawiane w ten sposób truskawki tworzą o 41% mniej rozłogów, o 30% mniej liści, o 28% mniej kwiatostanów oraz tworzą o 50% mniej owoców w porównaniu z truskawką uprawianą przez dwa lata na danym polu. Najczęściej do obniżenia wzrostu i plonowania truskawki dochodzi w 4–6 roku uprawy. Nie wszystkie uprawiane odmiany reagują jednakowo obniżeniem wzrostu i plonowania. Najmniej podatną na choroby korzeni jest odmiana ‘Senga Sengana’, natomiast bardziej podatna okazała się odmiana ‘Nida’. Stwierdzono, że długotrwała uprawa truskawki powoduje wzrost potencjału infekcyjnego gleby, co związane jest ze wzrostem jednostek propagacyjnych takich grzybów chorobotwórczych, jak Ascochyta fragaricola, Cercospora fragariae, Fusarium oxysporum, F. solani, Peronospora fragariae, Phytophthora cactorum, Pythium intermedium, P. ultimum, Plasmodiophora brassicae, Sclerotium rolfsii, Verticillium albo-atrum. W wyniku prowadzonych badań wykazano, że 1-2 letnia przerwa w uprawie truskawki nie ma większego wpływu na wzrost i plonowanie oraz porażenie roślin truskawki przez fitopatogeny. Ponadto przy długotrwałej uprawie truskawki na tym samym polu zwiększa się liczebność grzybów z rodzaju Penicillium: P. janthinellum, P. verruculosum, P. canescens, P. spinulosum. Przypuszcza się, że grzyby te w strefie korzeniowej roślin tworzą związki fitotoksyczne będące produktami ich metabolizmu.

Strawberry is a species sensitive to water shortages, especially during fruit growth and ripening. One method of limiting water loss in plant production involves the use of antitranspirants, which reduce plant transpiration. One method of limiting water loss in plant production involves the use of antitranspirants, which reduce plant transpiration. One of substances used for this purpose is, amongst others, natural terpene polymer di-1-p-menthene (pinolene). Research on the influence of a pinolene-containing antitranspirant (with the commercial name of Vapor Gard) on gas exchange parameters (intensity of net CO2 assimilation, intensity of transpiration, stomatal conductance for water, substomatal CO2 concentration), the water balance and the content of assimilation pigments (chlorophyll “a”, “b”, total chlorophyll, carotenoids) in the leaves of the cv. ‘Salsa’ strawberry was conducted in the years 2009–2010. The antitranspirant was used once at a concentration of 0.75% before flowering. The measurements were performed four times: before flowering (1st measurement date), when the plants were in full flowering (2nd measurement date), in the middle of the harvest season (3rd measurement date) and after the end of the harvest season (4th measurement date). Foliar application of the Vapor Gard antitranspirant decreases the intensity of strawberry transpiration without changing the CO2 assimilation activity. Plants sprayed with the tested preparation were characterised by a higher relative water content (RWC) in leaves and a higher value of the photosynthetic index of water use efficiency (WUE). The antitranspirant did not influence the content of assimilation pigments in straw-berry leaves. The values of the determined physiological features depended on the measurement date (developmental stage) of the tested strawberry cultivar.

Opis:
The aim of the experiment was to examine the effects of silicon (Si) on the growth and cropping of strawberry plants (Fragaria ananassa) and on the quality of the fruit. The study was conducted in 2013–2015 in the Experimental Orchard in Dąbrowice, belonging to the Research Institute of Horticulture in Skierniewice. The experimental objects were plants of the strawberry cultivars ‘Elkat’ and ‘Elsanta’, growing in a podsolic soil, low in humus, with the granulometric composition of light loam in the surface layer and with an average level of available nutrients. The experiment was designed in randomized blocks with three replications. An experimental plot was comprised of 20 strawberry plants planted at a spacing of 0.25 m × 1.0 m. The plants were treated with silicic acid, potassium silicate and calcium silicate. The preparations were applied annually to the soil in early spring (before the beginning of vegetation) at a dose of 90 kg Si per ha. Control plants were not treated with silicon. The results of the experiment were analysed statistically using the analysis of variance method. The differences between means were evaluated with Duncan’s test (p = 0.05). The results showed different responses of the tested strawberry cultivars to the silicon preparations used. In the case of ‘Elsanta’, the highest fruit yield was recorded in the plots where calcium silicate or potassium silicate were applied to the soil. It was also found that the use of potassium silicate, calcium silicate, and silicic acid reduced the occurrence of grey mould on the fruit of the cultivar ‘Elsanta’, but the differences as compared to the control were not statistically significant. The plants of the strawberry cultivar ‘Elkat’ treated with silicic acid produced the highest fruit yields, and the fruits were the least affected by grey mould. None of the silicon preparations affected the chlorophyll content of the leaves. It was also found that the use of the silicon preparations had no impact on the refractometric index of the fruits or their firmness. In both cultivars, the plants treated with silicic acid produced fruit with the highest Si content. The silicon content of the leaves of the tested strawberry cultivars was different for the individual years of the study. Depending on the year, the highest silicon content was found in the leaves of the plants treated with calcium silicate and silicic acid. Preparations containing silicon can be used in the commercial production of strawberry to reduce the occurrence of grey mould, but they cannot completely replace the chemical plant protection products designed for this purpose.

Opis:
In the current study, it was hypothesized that the addition of strawberry polyphenol-rich fractions to a high-fructose diet mitigates disorders in liver functions, lipid metabolism, and in the antioxidant and pro-inflammatory status of rats. Therefore, a fraction rich in ellagitannins and proanthocyanidins (EP), and a fraction containing compounds of both mentioned classes of polyphenols and additionally anthocyanins (EPA), in doses of 0.28 and 0.70 g/100 g, respectively, were added to a standard or a high-fructose diet administered to rats for six weeks. The EPA fraction was more beneficial in alleviating the consequences of consuming excess fructose in the diet than the EP fraction. Probably, that fraction containing considerable amounts of carbohydrates was more extensively metabolized by intestinal bacteria, which resulted in higher levels of cecal short chain fatty acids (SCFAs) as well as cecal and urinal ellagitannin metabolites. As a further consequence, diet supplementation with the EPA fraction caused more favorable changes in the levels of serum interleukin 6 and serum antioxidant capacity of water-soluble substances (ACW), in atherogenicity index lg((triglyceride/high-density lipoprotein cholesterol), hepatic oxidized glutathione as well as reduced to oxidized glutathione ratio). Efforts should be made to develop strawberry polyphenol-rich preparations containing the preferred anthocyanins, which is, however, difficult due to the instability of this class of phenolic compounds during the technological process.

This paper presents an influence of three different magnetic fields stimulation systems for growing strawberry fruits: permanent magnetic field generated by neodymium magnets, ”high” strengths slow varying amplitudes magnetic fields generated by coreless solenoids supplied by autotransformer and low-frequency and low-amplitude sinusoidal magnetic fields generator created for this research. The system is controlled by computer and allows for an independent control of up to 10 induction coils inducing magnetic fields with amplitudes from 0.1μT to 150μT and frequencies from 0.1Hz to 100Hz. The proposed set-up was used during the growing seasons for strawberry plants stimulation. An increase in the extract level was observed in the case of the alternating magnetic field stimulation with the parameters: frequency – from 50Hz to 100Hz and amplitude – from 50μT to 100μT.

Opis:
Demand for a reliable distinction of the strawberry flavour naturalness stood in the beginning of this research. An efficient chiral column with CP-Chirasil-Dex CB stationary phase was involved in headspace solid-phase microextraction-gas chromatography-mass spectrometry analysis of strawberry flavour in 6 strawberry cultivars, 7 samples of strawberry flavourings and 14 samples of strawberry syrups to evaluate the authenticity of flavour naturalness and reveal adulteration. Enantiomeric ratios of 8 selected chiral volatiles (methyl 2-methylbutanoate, ethyl 2-methylbutanoate, 2-methylbutanoic acid, linalool, α-ionone, γ-decalactone, γ-undecalactone, δ-dodecalactone) were evaluated. Seven chiral volatiles contributed to the revelation of synthetic origin. γ-Decalactone (enantiomeric ratios: 100∕0, 100∕0, 99∕1, 99∕1, 100∕0, and 99∕1 in strawberries; 100∕0 in 3 natural flavourings; 100∕0 in syrup with natural flavour) was the most contributive indicator of synthetic and natural strawberry flavour, followed by ethyl 2-methylbutanoate (enantiomeric ratios: 0∕100, 5∕95, 5∕95 in 3 natural flavourings, 0∕100 in syrup with natural flavour). The best chiral resolution was observed for α-ionone (RS>4). One syrup supposed to contain only natural strawberry flavouring was suspected to be adulterated regarding nearly racemic ratios of its four crucial chiral volatiles. Investigation of enantiomeric ratios of the unique selection of chiral volatiles and strawberry samples using the CP-Chirasil-Dex CB chiral column wider revealed possibilities for reliable recognition of strawberry flavour naturalness in complex matrices and in food samples in general.

Opis:
Przedmiotem badań było pięć form rodzicielskich truskawki oraz mieszańce pokolenia F1, uzyskane w wyniku krzyżowania diallelicznego. Analizę wyników przeprowadzono według trzeciej metody Griffinga, uwzględniającej krzyżowania odwrotne. Otrzymane w ten sposób potomstwa (20 kombinacji) oraz formy rodzicielskie wysadzono w układzie bloków losowych (4 powtórzenia, 30 roślin w każdym powtórzeniu). Celem pracy była ocena efektów ogólnej (GCA) i specyficznej zdolności kombinacyjnej (SCA) oraz efektów krzyżowań odwrotnych (RE) dla pięciu odmian truskawki. W latach 2005–2006 badano następujące cechy roślin: średni plon owoców z rośliny, średnia liczba owoców z rośliny, średnia masa pojedynczego owocu oraz wigor roślin (wyrażony jako średnia liczba liści na roślinie). Analizę statystyczną przeprowadzono na podstawie średnich wyników uzyskanych z pierwszego i drugiego roku owocowania. Oceniane formy rodzicielskie wykazywały zarówno dodatnie, jak i ujemne efekty ogólnej wartości kombinacyjnej. U odmiany Teresa wystąpiły najwyższe dodatnie efekty GCA dla plonu owoców z rośliny, natomiast w przypadku średniej liczby owoców, wartość GCA była ujemna. Odmiany Chandler, Kent i Senga Sengana wykazywały ujemne wartości GCA w stosunku do średniej liczby liści na roślinie. Stwierdzono również ujemne oddziaływanie odmiany Senga Sengana (potwierdzone efektami GCA) na wszystkie analizowane cechy mieszańców. Dodatnie efekty SCA dla wszystkich badanych cech wystąpiły w przypadku kombinacji Kent × Teresa i 1387 × Senga Sengana. Analizując wyniki krzyżowań odwrotnych, w przypadku plonu owoców z rośliny, stwierdzono, że odmiana Senga Sengana da lepsze efekty, jeżeli użyjemy jej jako matki, zaś odmiany Kent i Teresa zastosowane jako formy ojcowskie.
In this study five strawberry parental forms and F1 hybrids obtained from diallel crossing performed according to Griffings method III (with the effects of reciprocal crosses without inbred) were evaluated. The progeny (20 hybrids) and parental forms were planted in the field in a completely randomized block design (4 replicates, 30 plants in each plot). The aim of the study was to assess the general (GCA) and specific (SCA) combining abilities and the effects of reciprocal crosses (RE) in five strawberry cultivars. In 2005–2006 the following features of plants were analyzed: mean yield per plant, mean number of fruits per plant, mean weight of single fruit and vigour of plants (as a mean number of leaves). The statistical analysis was assessed on the basis of mean results obtained in the first and second year of fructification. The parental forms showed positive or negative results as regards the general combining ability. The highest positive GCA effect of yield per plant was recorded in cv. Teresa. In this cultivar, however, the GCA value for the average number of fruits per plant was negative. Cultivars Chandler, Kent and Senga Sengana showed negative GCA effects for average number of leaves per plant. Disadvantageous effects of cv. Senga Sengana upon all the analyzed traits in the hybrids were recorded. Positive SCA effects for all the traits were found in the progeny Kent × Teresa and 1387 × Senga Sengana. The results of reciprocal crosses upon the yield of fruit per plant indicated that cv. Senga Sengana can give better effects when it is used as a maternal component. In contrast, the cvs. Kent and Teresa provide better effects as parental forms.

Opis:
W pracy przedstawiono przebieg krzywych suszenia truskawek świeżych. Suszenie prowadzono w warunkach mikrofalowo-próżniowych. Zakres stosowanych ciśnień zawierał się pomiędzy 4-10 kPa. W przebiegu suszenia wyróżniono dwa okresy, które opisano równaniami empirycznymi. Określono również wartość skurczu suszarniczego.
The drying kinetics of fresh strawberries were presented. The drying process was carried out in microwave-vacuum conditions. The range of the pressures applied was between 4-10 kPa. During dehydration two periods of process were singled out and described with empirical equations. The shrinkage during drying was defined.
