‘Marketmore 76’ has been widely planted since it was first introduced 30 years ago and represents one of the most successful cucumber cultivars ever released. Despite the subsequent development of numerous higher-yielding hybrids ( Rowell et al

Cucumber ( Cucumis sativus ) is among the most widely grown vegetables in the world and is native to the Indian subcontinent ( Sebastian et al., 2010 ). It spread eastward to China ≈2000 years ago and westward to Europe 700 to 1500 years ago ( Weng

Cucumber ( Cucumis sativus ) production in the eastern and midwestern United States is subject to severe losses resulting from fruit rot caused by the soilborne oomycete pathogen, Phytophthora capsici ( Granke et al., 2012 ; Sonogo and Ji, 2012

The cucumber ( Cucumis sativus L.), which belongs to the Cucurbitaceae family, is a commonly consumed vegetable. It is an economically important crop that is widely cultivated throughout the world. Cucumber plants often experience biotic and
Abstract
Methyl-2-chloro-9-hydroxyfluorene-(9)-carboxylate (chlorflurenol) effectively promoted parthenocarpic fruit development in gynoecious pickling cucumbers, Cucumis sativus L. Treatment with chlorflurenol increased yields of fruits under both greenhouse and open-field conditions. Yields were dependent on the degree of genetic parthenocarpy for each cultivar. Parthenocarpic yields following chlorflurenol treatment were higher with night temperatures of 16° and 21°C than with 27°.
Abstract
Three cucumber (Cucumis sativus L.) populations were evaluated to determine the effects of several seed harvesting and handling procedures on seed quality. Fruit maturity at seed harvest, fermentation duration in seed extraction, seed storage time, and germination temperature all significantly influenced germination percentage and rate. About 30% of the observed variation in germination percentage was due to interactions between handling factors rather than to main effects of factors. Although germination in excess of 90% was observed for some combinations of factors with as little as 28 days of fruit maturity (post-pollination), the advantages of greater seed maturity at harvest were evident for rate of germination and tolerance to long fermentation times. Positive responses to short fermentation durations (≤4 days) occasionally were observed, but longer fermentation durations were markedly deleterious under some conditions. Six months of seed storage were effective in improving germination of seed at 15° and 20°C, but had little effect on germination at 25°. The 3 cucumber populations were markedly different in response to some seed handling factors.
