Expansion growth in response to auxin in chicory root slices is greater than that reported for any other fleshy tissue. Responsiveness depends on time of harvest and duration of root storage.

In young chicory plantlets [Cichorium intybus L. Witloof cv. Flash), nitrate assimilation takes place mainly in the roots. Nitrate reductase activity (NRA) was measured in roots deprived of shoot control by excision and transferred into a sucrose-containing medium. Such a treatment resulted in a drop of about 60% of NRA within 3 h. The level of NR protein decreased after 12 h and the level of N...

Modern and sustainable production of safe and healthy high quality vegetables for human consumption is nowadays the goal of many producers. Chicory (Cichorium intybus L.) has become an important crop used as food in many countries over the past decade. In this work fi eld and glasshouse trials were conducted to compare phenolic profi les of hydroponically forced leaves and leaves produced as co...

Pectins are major components of the primary plant cell wall. They can be both methylesterified and acetylesterified and de-esterification occurs by specific esterases. Proteins extracted by NaCl treatment from root cell walls of two chicory varieties (Cichorium intybus L. cv. Nausica and Arancha) sampled in an experimental field every 2 weeks between July 2002 and January 2003 were analysed by ...

Organic dairy farmers often introduce alternative pasture species, such as chicory (Cichorium intybus) and narrow-leaved plantain (Plantago lanceolata), to their swards because of their higher mineral contents, yet they are concerned about the presence of weed species such as docks (Rumex spp.) and dandelion (Taraxacum officinale). The mineral content and nutritive value of both desired and les...

Major chloroplast pigments in five leafy vegetables (chicory-Cichorium intybus, cv. 'Anivip' and cv. 'Monivip', dandelion-Taraxacum officinale, garden rocket-Eruca sativa and wild rocket-Diplotaxis tenuifolia), commonly consumed in Mediterranean countries, have been separated by high-performance liquid chromatography (HPLC) on a reversed-phase column. Three classes of pigments were identified a...
