Quantitative Changes in Buckwheat Flavonoid Substances During Seedling Development.

Changes of Polyphenolic Substances in the Anatomical Parts of Buckwheat (Fagopyrum esculentum Moench.) during Its Growth Phases

In this study the changes of total polyphenolics in different anatomical parts (stems, leaves, flowers and seeds) of common buckwheat (Fagopyrum esculentum Moench.) during vegetation period were analysed. The content of total polyphenolics was evaluated in growth phase I (formation of buds), phase II (at the beginning of flowering), phase III (full blossoming) and phase IV (full ripeness). In a...

Anthocyanin Formation in Excised Segments of Buckwheat-Seedling Hypocotyls.

Recent studies of anthocyanin formation have involved the use of a varied assortment of plant systems: seedlings, leaves, fruits, petals, callus cultures, and Lemnaceous flowering plants (2,9). Each of these kinds of material possesses certain advantages and certain disadvantages. In the dark-grown buckwheat seedling anthocyanin synthesis can be induced in the hypocotyl by exposure of that orga...

The Impact of Short-Term Exposure to Pb and Cd on Flavonoid Composition and Seedling Growth of Common Buckwheat Cultivars

The aim of this study was to compare the tolerance of seedlings of three Polish buckwheat cultivars (Hruszowska, Kora, and Luba) for short-term exposure to Pb and Cd. Seedlings were grown under controlled conditions in Hoagland nutrient solution, with the addition of low/high Pb or Cd ions (0.01 and 1.00 mM, respectively). After 3 days of treated seedling growth, the levels of total anthocyanin...
