    Description / Table of Contents: Zusammenfassung Die Absicht dieser Studie war es, den Zusammenhang zwischen der Besorgtheit über Ernährung und den Lebensmittelkonsum bei 533 Universitätsstudenten (112 Männer und 421 Frauen), Durchschnittsalter 21.7±2.1 Jahre, zu untersuchen. Fisch, Milchprodukte und Obst wurden in ausreichendem Maße, Getreide und Gemüse hingegen wurden in kleineren Mengen als empfohlen, gegessen. Die Männer verzehrten mehr Milch, Fleisch, Brot und alkoholische Getränke, während die Frauen mehr Obst und Gemüse als die Männer aßen. 35,4 % der Studenten äußerten Besorgnis besonders über die Aufnahme von Fett und Cholesterin, 24,5 % waren speziell an der Gewichtskontrolle interessiert und 18,2 % sagten, ihre Hauptsorge gelte der korrekten Einnahme von Vitaminen und Mineralstoffen. 21,6 % der Teilnehmer hatten keine besondere Sorge bezüglich der Ernährung. Multiple Regressionsanalysen zeigten keinen Unterschied zwischen Männern und Frauen oder dem Body Mass Index (BMI) auf, was die Besorgtheit über die Ernährung betrifft. Aber man stellte einen altersbedingten Unterschied fest. Mit zunehmendem Alter zeigten die Studenten mehr Interesse zum Thema „Ernährung“, vor allem im Zusammenhang mit Vitaminen und Mineralstoffen. Die Besorgnis über die Gewichtskontrolle stieg mit steigendem BMI. Von denen, die ihr Gewicht reduzieren wollten, hatten allerdings 42,2 % der Frauen gegenüber 7,4 % der Männer einen BMI von 〈20 kg/m2. Da diese Studenten bereits sehr schlank waren (unter den empfohlenen Werten), aber trotzdem noch Gewicht verlieren wollten, könnte dies zu Mangelerscheinungen führen. Zusammenhänge zwischen der Besorgtheit und der Ernährungsweise waren kaum zu beobachten. Obwohl die Einnahme von Fett und Cholesterin als solche Anlass zur Besorgnis war, wurden zum Beispiel relativ viel Fleisch und Eier verzehrt. Es wurde eine Beziehung gefunden zwischen der Sorge um den Vitamin- und Mineralstoffgehalt der Nahrung und der Einnahme von Nahrungsergänzungsmittel sowie zwischen der Sorge um das Körpergewicht und der Einnahme von Produkten zur Gewichtsreduktion. Für die Lehrer der Ernährungswissenschaft kann diese Information behilflich sein, um ihre Kurse und Programme zu gestalten.
    Notes: Summary The aim of this investigation was to study the relationship between concern about nutrition and food consumption in 533 university students (112 men and 421 women), aged 21.7±2.1 years old. Fish, dairy products and fruit were consumed in quite satisfactory quantities though cereals and vegetables were consumed less frequently than recommended. Men were found to consume greater quantities of milk, meat, bread and alcoholic drinks, while women ate more fruit and vegetables than men. 35.4 % of subjects said they were especially concerned about the intake of fat and cholesterol, 24.5 % expressed special interest in weight control and 18.2 % recorded worries about the intake of vitamins and minerals. 21.6 % of subjects expressed no worries at all. Multiple regression analysis showed no differences in concern about nutrition with respect to the sex or body mass index (BMI) of subjects. However, as age increased, the number of subjects expressing no concern fell whilst worries over the quantity of vitamins and minerals in the diet increased. Worries about bodyweight were found to rise with BMI. However, amongst those who wanted to lose weight, 42.2 % of women and 7.4 % of men had a BMI 〈20 kg/m2. These persons, already very slim (below recommended values), still wished to lose weight and could become susceptible to nutritional imbalances. Relationships between concerns and food habits were scarce. Although fat and cholesterol were a concern in theory, the consumption of foodstuffs such as meat and eggs was quite high. However, relationships were found between concern over the vitamin and mineral content of the diet and the intake of supplements, and concern over bodyweight and intake of products that aid slimming. Nutrition educators may find this information useful in the design of their messages and educational programs.

    Notes: Abstract   Fino lemon trees (Citrus limon L. Burm. fil.) on sour orange (Citrus aurantium L.), growing on a low water retention capacity soil, were submitted to three different irrigation treatments over four years: 100% ETc all year (T-0), 25% ETc all year except during the rapid fruit growth period when 100% ETc was applied (T-1) and 100% ETc all year, except during the rapid fruit growth period when 70% ETc was applied (T-2). A water saving of 30 and 20% was achieved in the T-1 and T-2 treatments, respectively. The plant responses to irrigation treatments were similar in all the years studied. Leaf water potential decreased during deficit irrigation periods in T-1 and T-2 treatments. Larger differences were found in values taken at predawn (Ψ pd) than at midday (Ψ md), indicating that Ψ pd is a more useful indicator of plant water status. There was neither osmotic nor elastic adjustment in response to deficit irrigation treatment. A clear separation between the main periods of shoot and fruit growth was found, which can be considered an advantageous characteristic in applying regulated deficit irrigation strategies. Onset of the critical period of rapid fruit growth could be determined precisely by considering the decrease in relative fruit growth rate values. T-2 treatment did not induce a significant reduction in total yield, but it caused a delay in reaching marketable lemon fruit size. T-1 treatment did not affect total yield, with a reduction in yield on the first pick occurring in only one year. Chemical characteristics of lemon fruit were not significantly modified by irrigation treatment.

    Notes: Abstract Prunus necrotic ringspot Ilarvirus (PNRSV) is a pollen and seed-borne ilarvirus affecting most Prunus spp. The location of the virus in infected nectarine pollen grains was investigated by molecular hybridisation, RT-PCR and in situ hybridisation. The first two approaches revealed an internal location of the virus. In situ hybridisation demonstrated the virus in the bicellular pollen grain, where it was present in the cytoplasm of the vegetative cell but not in the generative cell. This result seems to indicate that the sperm cells, formed by the mitosis of the generative cell, are not involved in virus transmission to seed. Other possible mechanisms are discussed.

    Notes: Three processes for preparing peeled pickled garlic were studied: (P) packing directly with an acidified brine, followed by pasteurization (90°C, 8 min); (B) blanching with hot water (90°C, 15 min) before packing, followed by a preservation treatment (pasteurization, preservatives + refrigeration); and (MB) same as B, except that microwave blanching was used (120g garlic cloves, 825W, 1.5 min). All products were microbiologically stable but fructans were hydrolyzed during storage at 27°C. A green pigment was also apparent in (P). Products from (B) or (MB) had better quality than that from (P). Most stable and best quality products resulted from the blanching treatments and water blanching resulted in the product with best color.
