Consumer interest worldwide in the quality of vegetable products has increased in recent years. Product quality is a complex issue. As well as visual characteristics, properties such as texture, the content of minerals and vitamins, flavor and other organoleptic characteristics must be considered. In addition, new knowledge shows that vegetables are appreciated for their beneficial health effects in humans and underlines the importance of nutraceutic properties. Many research studies have documented methods for achieving a high-quality vegetable product. Indoor production for fresh vegetables offers advantages compared to outdoor production with regard to quality assurance principally, because the products are not exposed directly to the rapid changes of climate conditions. On the other hand, vegetable cultivation in a greenhouse under artificially created conditions also affects the internal quality of the product. This is reflected in a different taste and flavor compared with field vegetables. Changes ...

Greenhouse Tomato Fruit Quality

A cellular hypothesis for the induction of blossom-end rot in tomato fruit

Blossom-end rot of tomato (Lycopersicon esculentum Mill.): a calcium- or a stress-related disorder?

The possible causes of blossom-end rot (BER) in tomato fruit were investigated by comparing the uptake of calcium by the roots, the distribution of 45 Ca within the fruit and the vascular bundle network in the fruit of susceptible cultivars (Calypso and Spectra) with those of a less susceptible cultivar (Counter) grown in a range of salinities (electrical conductivity of 5, 10 and 15 mS cm -1 ). The daily calcium uptake rates at 5 mS cm -1 , as estimated from the xylem exudation of the decapitated stem stump in young plants of Calypso and old plants of Spectra, were lower than that of Counter
