The aim of the study was to determine the effects of time and temperature during the pre-treatment in hot water semi-products obtained from potatoes. This treatment results in leaching of reducing sugars and influences on the texture of fried potato products. Studies were carried out on samples of potatoes in the form of slices (having a diameter of 57 mm and a thickness of 4 mm) and sticks having a cross section of 10×10 mm and a length of 100 mm. The semi-products formed had a comparable weight of ca. 10 g. Prepared semi-product were immersed in demineralised water at temperature 20°C, 30°C, 40°C. The immersion time was 5 min, 10 min, 15 min, 20 min. Ater 10 minutes from frying ended, the products were subjected to loads in which unit cutting resistance values were measured (N:mm-1), which served as the texture indicators. The product shape, temperature of water for washing sugars and treatment time are statistically significant for product texture. Lower texture values are found in the slices. The sample tested significantly differs, in unit cutting resistance values, from other samples subjected to washing ope1ration.

The paper presents the results of the research of the size and shape of parenchyma tissue cells in potato tubers depending on the direction and site of sampling in tubers. An optical confocal microscope was used to observe samples in their natural state. The investigation was carried out for 1 mm thick samples cut from cylindrical samples (10x10 mm)taken in two mutually perpendicular directions of the inner and outer core of each variety. The analysis was done ten times.The methods developed for the composition and image analysis ensure obtaining a sufficient number of cells to determine tissue structure parameters (surface, shape, elongation and number of cells per 1 mm2) and decays of these parameters were obtained. Statistical analysis was performed using the -Kolmogorov-Smirnov compliance test.Arelationship between the direction of sampling and the size and shape of the inner core of cells was found. Greater surface area and elongation of the inner core cells for the longitudinal direction in the tuber (stolon – top) was demonstrated. There was no such a correlation for the outer core in the tubers of the cultivars examined.

The objective of the study was to investigate the impact of sulphur application on the content (g kg-1) and uptake (kg ha-1) of phosphorus and potassium with the yield of potato tubers. In 2004-2006, a field experiment on potato was conducted, in which S was applied in different forms (elemental and K2SO4) and doses (0, 25 and 50 kg ha-1). The content and uptake of P and K in the dry mass of potato tubers was significantly increased by sulphur. The application of sulphur increased the P content and uptake irrespective of the S dose, but elemental S proved more effective. The K content was the highest when sulphate was applied at 50 kg S ha-1. The K uptake by tubers was significantly increased by both of the applied doses versus the control plots. The tuber yield depended substantially on the rate of S fertilizer. Sulphur applied as sulphate increased the content of SO4-S in the soil. The application of elemental S in a dose of 50 kg ha-1 decreased the soil pH. The soil content of total C was dependent on each dose and form of the applied sulphur. The content of SO4-S and total C in the soil positively correlated with the P content and uptake by potato tubers. A negative correlation was found between the pH value and content and uptake of P by potato tubers. No correlation was found between K and soil parameters, but a positive correlation was found between the P and K uptake by tubers and between the P and K uptake versus tuber yield.

The study was conducted over the years 2004–2006 in experimental plots located in Bałcyny. A multi-purpose, late potato cultivar, Jasia, was grown. The experimental factors were as follows: I – mineral fertilization levels: A (N – 80 kg ha⁻¹, P – 80 kg ha⁻¹, K – 120 kg ha⁻¹), B (N – 120 kg ha⁻¹, P – 144 kg ha⁻¹, K – 156 kg ha⁻¹), II – foliar fertilization: 1 (Basfoliar 12-4-6 – 8 dm³ ha⁻¹), 2 (ADOB Mn – 4 dm³ ha⁻¹), 3 (Solubor DF – 2 dm³ ha⁻¹), 4 (ADOB Mn – 2 dm³ ha⁻¹ + Basfoliar 12-4-6 – 4 dm³ ha⁻¹), 5 (ADOB Mn – 2 dm³ ha⁻¹ + Solubor DF – 1 dm³ ha⁻¹), 6 (Basfoliar 12-4-6 – 4 dm³ ha⁻¹ + Solubor DF – 1 dm³ ha⁻¹), 7 (Basfoliar 12-4-6 – 2.7 dm³ ha⁻¹+ADOBMn – 1.3 dm³ ha⁻¹+SoluborDF – 0.7 dm³ ha⁻¹), 8 (control treatment without foliar fertilization). The health status of potato tubers was studied after five-month storage. The rates of tuber infection by Streptomyces scabies and Rhizoctonia solani were estimated on 100 tubers selected randomly of particular treatments, according to a nine-point scale, and were presented as a percentage infection index. The symptoms of soft rot (Pectobacterium carotovorum subsp. carotovorum), late blight (Phytophthora infestans) and dry rot (Fusarium spp.) were evaluated in 5 kg samples for each treatment. The results were expressed as a percentage of the mass of infected tubers. Foliar fertilization and the levels of mineral fertilization NPK did not affect the severity of common scab symptoms. Significantly higher rates of infection by R. solani were observed in tubers from the control treatment without foliar fertilization and from the treatment with a lower level of mineral fertilization (A). The symptoms of soft rot (4.6% of the mass of infected tubers) and late blight (1.3%) were strongest in 2006, while the symptoms of dry rot (2.7%) – in 2005. The severity of diseases caused by the above pathogens was greater in tubers grown in plots with a higher level of mineral fertilization (B) – N 120 kg ha⁻¹, P 144 kg ha⁻¹, K 156 kg ha⁻¹ (1.3 to 4.1% of the mass of infected tubers) than in tubers grown in plots with a lower level of mineral fertilization (A) –N80 kg ha⁻¹, P 80 kg ha⁻¹, K 120 kg ha⁻¹, (0.8 to 3%). The combined application of foliar fertilizers reduced the percentage mass of tubers infected by P. carotovorum subsp. carotovorum and P. infestans to the highest degree.

Badania przeprowadzono w latach 2004–2006 na poletkach doświadczalnych w Bałcynach. Uprawiano wszechstronnie użytkowaną, późną odmianę ziemniaka Jasia. W doświadczeniu uwzględniono dwa czynniki: I – poziomy nawożenia mineralnego: A (N – 80 kg ha⁻¹, P – 80 kg ha⁻¹, K – 120 kg ha⁻¹), B (N – 120 kg ha⁻¹, P – 144 kg ha⁻¹, K – 156 kg ha⁻¹) i II – nawożenie dolistne: 1 (Basfoliar 12-4-6 – 8 dm³ ha⁻¹), 2 (ADOB Mn – 4 dm³ ha⁻¹), 3 (Solubor DF – 2 dm³ ha⁻¹), 4 (ADOB Mn – 2 dm³ ha⁻¹ + Basfoliar 12-4-6 – 4 dm³ ha⁻¹), 5 (ADOB Mn – 2 dm³ ha⁻¹ + Solubor DF – 1 dm³ ha⁻¹), 6 (Basfoliar 12-4-6 – 4 dm³ ha⁻ ¹ + Solubor DF – 1 dm³ ha⁻¹), 7 (Basfoliar 12-4-6 – 2,7 dm³ ha⁻¹ + ADOB Mn – 1,3 dm³ ha⁻¹ + Solubor DF – 0,7 dm³ ha⁻¹), 8 (kontrola bez nawożenia dolistnego). Po 5-miesięcznym przechowywaniu bulw przeprowadzano ocenę ich zdrowotności. Nasilenie parcha zwykłego (Streptomyces scabies) i ospowatości bulw (Rhizoctonia solani) określano na 100 bulwach z kombinacji, według 9° skali, a wyniki podano w % jako indeks porażenia. Objawy mokrej zgnilizny (Pectobacterium carotovorum subsp. carotovorum), zarazy ziemniaka (Phytophthora infestans) i suchej zgnilizny bulw (Fusarium spp.) oceniano w 5-kilogramowej próbie bulw z każdej kombinacji. Wyniki przedstawiono w procentach masy porażonych bulw. Nawożenie dolistne oraz poziomy nawożenia mineralnego NPK nie różnicowały nasilenia objawów parcha zwykłego. Istotnie wyższe porażenie R. solani zanotowano na bulwach w kombinacji kontrolnej bez nawożenia dolistnego i z nawożeniem mineralnym w niższej dawce (poziom A). Największe objawy mokrej zgnilizny bulw (4,6% masy porażonych bulw) i zarazy ziemniaka (1,3%) stwierdzono w 2006 r., a suchej zgnilizny (2,7%) – w 2005 r. Zanotowano silniejsze objawy chorób powodowanych przez wymienione patogeny na bulwach pochodzących z roślin uprawianych w kombinacji z zastosowanym wyższym nawożeniem mineralnym doglebowymB– N 120 kg ha⁻¹, P 144 kg ha⁻¹, K 156 kg ha⁻¹, (1,3 do 4,1% masy porażonych bulw) niż u roślin w kombinacji z niższym nawożeniem A – N 80 kg ha⁻¹, P 80 kg ha⁻¹, K 120 kg ha⁻¹ (od 0,8 do 3%). Łączne stosowanie nawozów dolistnych najbardziej ograniczało procent masy bulw porażonych P. carotovorum subsp. carotovorum i P. infestans.

The research was carried out in 2002-2006 at the Crop-Growing Product Storage and Processing Laboratory, Department of Horticulture, Lithuanian University of Agriculture Animal Husbandry Institute of Lithuanian Veterinary Academy. 15 amino acids were determined in the studied samples of potato tubers of 5 cultivars including 9 essential amino acids. Essential amino acids make up 38-45% of all the amino acids. In potato tubers, the dominating amino acids were leucine and valine, the lowest amount was of methionine and histidine. Dominating alterable amino acids were glutamic and aspartic acids. The latter were one of the most mobile during the storage period. During the whole period of storage, the lowest changes were observed in the following: lysine in cv. Goda tubers, histidine in cv. Nida tubers, methionine, histidine and isoleucine in potato tubers of the cv. Vaiva. Alterable amino acids, i.e. glycine, alanine and tyrosine, during the whole period of storage changed the least in the potato tubers of all cultivars. The decrease in the protein content during the storage period causes the increase in the tyrosine content. Tyrosine is not desirable in potato tubers due to the fact that it negatively affects the color of raw potato tubers. Under the increasing amount of tyrosine, potatoes darken faster. According to the data of our research, the amount of tyrosine in potato tubers of all cultivars was not significant. After carrying out the correlation analysis between the darkening of raw potato tubers and the amount of tyrosine, a weak correlation was determined (r = -0.4).

W warunkach klimatycznych Litwy ziemniaki przechowywane są zależnie od kierunku użytkowania, od października do czerwca włącznie. Zalecana wysoka temperatura (około 8°C) przechowywania ziemniaków przeznaczonych do przetwórstwa spożywczego prowadzi do intensywnego kiełkowania. Od wielu lat badane są środki przeciwko kiełkowaniu mniej szkodliwe lub pochodzenia naturalnego. Zawartość aminokwasów w bulwach ziemniaków najczęściej zależy od cech odmianowych, warunków uprawy i przechowywania. Celem badań było określenie wpływu inhibitorów wzrostu na zmiany ilościowe aminokwasów w czasie magazynowania ziemniaków w ciągu 8 miesięcy. W badaniach przechowalniczych przetestowano odmiany ziemniaków: Goda, Gloria, Nida, Vaiva i Vokë. Po 8 miesiącach przechowywania oznaczono w bulwach 15 aminokwasów, w tym 9 niezbędnych. 33-50% sumy aminokwasów stanowiły kwas glutaminowy i asparaginowy. Najmniej wykryto histydyny, metioniny, glicyny. Tyrozyna we wszystkich bulwach badanych odmian ziemniaków występowała w niedużych ilościach - około 2 g·kg⁻¹ suchej substancji. Spośród niezbędnych aminokwasów decydująco większe ilości obserwowano leucyny i waliny, natomiast najmniejsze metioniny. Ilość nie niezbędnych aminokwasów: glicyny, alaniny i tyrozyny przez cały okres przechowywania zmieniała się najmniej. Stwierdzono, że naturalne inhibitory wzrostu pozytywnie wpływały na jakość przechowywanych bulw ziemniaka poprzez zmniejszenie ilości aminokwasów w ciągu 5 miesięcy przechowywania. Stosowanie naturalnych, efektywnych środków ograniczających kiełkowanie jest szansą na wyeliminowanie szkodliwych środków chemicznych stosowanych podczas przechowywania.

Laboratory experiments were carried out in the laboratory of Raw Materials for Food Agronomic and Livestock Research of Agronomy Faculty of the Lithuanian University of Agriculture in 2009. The investigation focused on Solanum tuberosum L. cv. ‘Goda’ and Solanum tuberosum L. cv. ‘Solara’. The aim of this paper was to identify the effect of high/low temperatures on the potato tuber sprout initiation at the apical dominance stage. Potato tubers were exposed to different temperatures (-10°C, +5°C, +30°C, +40°C, +50°C) and time (30, 60 and 90 min) regimes. Control potato tubers were stored in light, + 18°C and photoperiod of 12 h. Before the test, the tubers were numbered, fixed eyes number on the upper, middle and lower parts of the tubers. After obtaining these conditions it was assessed that germinated eyes were numbered on the upper, middle and lower parts of the tubers. The dynamics of tuber sprout was determined with an interval of 7-14-21 days after high / low temperatures effect, and all seed tubers were analyzed. The present study confirmed that high (+40, +50°C)/low (-10°C) temperatures broke the apical sprout and increasing of the quantity of sprouting eyes.

Badania przeprowadzono w laboratorium Food Agronomie and Livestock Research Wydziału Rolniczego na Litewskim Uniwersytecie Rolniczym w 2009 roku. Jako surowiec zastosowano bulwy ziemniaka (Solanum tuberosum) odmian Goda i Solara. Celem badań było określenie wpływu oddziaływania wysokiej/niskiej temperatury na zapoczątkowanie przesunięcia dominacji kiełka wierzchołkowego. Bulwy ziemniaka poddano ekspozycji na działanie różnych temperatur (-10°C, +5°C, +30°C, +40°C, +50°C) w różnym czasie (30, 60 i 90 min). Kontrolną próbę bulw przechowywano w temperaturze +18°C, na świetle przez okres 12 godzin. Bulwy przed oceną liczono, określano liczbę oczek w części górnej, środkowej i dolnej. Po zadziałaniu stosowanych w badaniach czynników stwierdzono kiełkujące oczka na każdej z części bulw. Dynamikę kiełkowania bulwy określano w przedziałach: po 7-14-21 dniach oddziaływania wysokiej/niskiej temperatury na każdego użytego w badaniach sadzeniaka. Przeprowadzone badania potwierdziły, że wysoka (+40, +50°C)/niska (-10°C) temperatura przerywa dominację kiełka wierzchołkowego i zwiększa liczbę kiełkujących oczek.
