Cucumis sativus L., which belongs to the Cucurbitaceae family, is cultivated worldwide as a vegetable crop. The fruit of C. sativus (cucumber) is used not only as food, but also in folk medicines and folk cosmetics. The leaves, stems and roots of C. sativus are reportedly used in Chinese folk medicine as antidiarrheal, detoxicant and antigonorrheal agents. However, these are not major uses, so ...

Cucumber is generally a thermophilic species; however, cultivars have been selected for higher yield during winter cultivation in unheated glasshouses in temperate regions. We tested whether photosynthesis in these varieties had greater chilling tolerance. There was no difference in the instantaneous reduction of photosynthesis at low temperature between four winter glasshouse and four summer f...

Knowing the extent and structure of genetic variation in germplasm collections is essential for the conservation and utilization of biodiversity in cultivated plants. Cucumber is the fourth most important vegetable crop worldwide and is a model system for other Cucurbitaceae, a family that also includes melon, watermelon, pumpkin and squash. Previous isozyme studies revealed a low genetic diver...

Isolations of polymorphic sequences of two pairs of the NIL lines of cucumber (Cucumis sativus L.), which differ with respect to sex, were carried out using the subtraction hybridization methods of DSC (Differential Subtraction Chain) and GDDSC (Genetically Directed DSC). 266 DSC tags were isolated from the entire genome region, and 38 GDDSC tags were isolated from the region containing the sex...

The formation of protochlorophyllide and protochlorophyllide phytyl ester was investigated during etioplast biogenesis in order to study the biosynthetic relation of these two compounds. Protochlorophyllide accumulates slowly during the first 2 days of germination, its rate of formation increases sharply during the 3rd day, and then it decreases. Protochlorophyllide phytyl ester starts accumula...

OVATE family proteins (OFPs) are plant-specific with a conserved domain that regulate plant growth and development. Although OFPs have been studied in several species, their biological functions remain largely unknown cucumber (Cucumis sativus L.). This study identified 19 CsOFPs distributed on seven chromosomes cucumber. Most CsOFP genes were expressed reproductive organs, but different expres...

Monitoring of nitrate (NO(3)(-)) and nitrite (NO(2)(-)) content in agricultural products in Slovenia has been carried out since 1996. The results of monitoring over the period 1996-2002 are presented. During this time 924 samples of 14 different agricultural products (potato, lettuce, apples, carrot, silage maize, cabbage, grapes, peaches, string beans, cereals, pears, cucumbers, strawberries a...

The distributions of endosulfan (ED) residues (α-, β-isomers, and sulfate-metabolite) in cucumbers grown in soils treated with ED at concentrations of 20 and 40 mg kg-1 were assessed using indoor and outdoor experiments. In all treatments, degradation rates of the α-isomer in soils were higher than that of the β-isomer. In the indoor tests, uptake amounts of total ED by cucumbers, after 15 d of...

We show that the chromaticness of the visual signal that results from the two-color mixing achieved through an optically enhanced binocular device is directly related to the band ratio of light intensity at the two selected wavebands. A technique that implements the band-ratio criterion in a visual device by using two-color mixing is presented here. The device will allow inspectors to identify ...

Previous studies (Costilow et al., 1955) demonstrated that the yeasts found to be most prevalent in cucumber fermentations were completely inhibited by 0.01 per cent sorbic acid in an 8 per cent salt (NaCl) medium at pH 4.6. As the pH was increased and/or the salt concentration decreased, more sorbic acid was required for complete inhibition of some of the yeasts tested. Cultures of Pediococcus...
