The study concerned the effect of elicitors on the contents of free flavonoids and phenolic acids, as well as their esters and glycosides, and contents of minerals in 7-day sprouts of common buckwheat. An aqueous solution containing a mixture of sodium silicate and Fe-EDTA (SIL-Fe) was compared with the same concentration of sodium silicate alone (SIL) and water (control). Phenolic compounds were analysed using an HPLC–MS/MS apparatus equipped with an ion-trap mass spectrometer, and analyses were conducted by multiple reaction monitoring of selected negative ions. The contents of macro- and microelements in sprouts were determined by the ICP-AES method, after sample mineralization in a mixture of HNO₃ and H₂O₂. The study showed that SIL-Fe influenced the accumulation of individual phenolics in buckwheat sprouts in different ways. Among the major flavonoids in the buckwheat sprouts treated with SIL-Fe, the content of free forms and esters of (-)-epicatechin and glycosides of quercetin as well as the total content of flavonoids decreased. Elicitation of buckwheat sprouts with SIL and SIL-Fe reduced the contents of calcium, potassium, copper, and zinc; however, the SIL-Fe treatment caused a 5-fold increase in iron content and a 2-fold increase in silicon content. The ratio of total flavonoids to the iron content of SIL-Fe-treated sprouts was 11.5, which was substantially lower than in the control, where it reached 64. The results of this study indicate that it is possible to produce buckwheat sprouts with a high content of flavonoids and fortified with iron, which may increase the availability of this element.

Seedlings of four vegetable species (maize, tomato, radish and onion) were treated for 7 days with methyl jasmonate (MeJA) vapors. MeJA accelerated senescence process of plant tissues and accumulation of anthocyanins. The only exception were hypocotyls of radish, which was found to decrease of the anthocyanin content under the influence of MeJA. It has been shown that MeJA has a different impact on the content of free biogenic amines. In case of leaves and epicotyls of maize and tomato hypocotyls, MeJA had no effect on levels of putrescine (Put). The leaves of tomatoes have shown to increase the putrescine level as a result of the impact of MeJA vapors. However, in the tissues of radish and onion very large decline in putrescine and spermidine content under the influence of the phytohormone were observed. The presence of small amounts of spermine was found only in tissues of radish, and onion, which does not affect the use of MeJA. In tissues of maize the presence of a significant content of 2-phenylethylamine (PEA) were found. Use for 7 days of MeJA vapors resulted in 3-fold increase in the content of the PEA in maize leaves. Small levels of the amine has also been found in tomato hypocotyls, where use of MeJA caused reduction its content. Obtained results show a little relationship between the activity of the studied enzymes (ornithine decarboxylase (ODC), lysine decarboxylase (LDC) and tyrosine decarboxylase (TYDC)) and the contents of the amines in seedlings of four vegetable species. No free cadaverine and tyramine were found, and therefore probably both polyamines might be present as conju-gates. Putrescine also may be present in bound form. Moreover, since putrescine can be synthesized directly from ornithine or indirectly from arginine via agmatine, the activity of ODC alone did not give a full picture of the impact of MeJA on Put accumulation.

Exogenously applied jasmonic acid methyl ester (JA-Me) inhibited biosynthesis and accumulation of anthocyanins in hypocotyls of seedlings of etiolated common buckwheat (Fagopyrum esculentum Moench) exposed to light. The phenomenon was observed in experiments with various methods of JA-Me treatment, in whole seedlings and in excised hypocotyls. Even very low quantities of JA-Me taken by seeds during imbibition were enough to inhibit anthocyanin synthesis in buckwheat hypocotyls. This means that there are no significant barriers to the transport and action of JA-Me in buckwheat seedlings, as solute and in gaseous form. Although JA-Me inhibited accumulation of anthocyanins in buckwheat hypocotyls. it had no effect on phenylalanine and tyrosine ammonia-lyase activity. Such JA-Me action suggests that it can act not in the first but in later steps of anthocyanin biosynthesis. JA-Me had no effect on the level of anthocyanins in cotyledons or on hypocotyl growth, but clearly inhibited the growth of main roots of buckwheat seedlings.

We examined the response of common buckwheat (Fagopyrum esculentum Moench) seedlings, as a nontarget plant, to various doses of glyphosate applied to the root zone or to the shoots. Glyphosate was used at 0.1, 0.5, and 1.0 mM concentrations. The study was conducted on seedlings grown in hydroponic cultures under controlled growth conditions. Primary root and shoot growth, anthocyanin and photosynthetic pigment contents were measured to assess the effects of exposure to glyphosate. Glyphosate applied to shoots had a considerably higher impact on the growth of primary roots and shoots of seedlings. Low glyphosate concentrations produced an increase in anthocyanin content of hypocotyls, regardless of the mode of its application. Increasing the concentration of glyphosate applied to the root zone resulted in a gradual increase in anthocyanin content in cotyledons. Our overall results show that in hydroponically grown common buckwheat seedlings, glyphosate is less phytotoxic when applied to the root zone than when applied to the shoot. Low doses of glyphosate applied to the root zone stimulate root and shoot growth and increase the anthocyanin levels in cotyledons. The phytotoxicity of glyphosate was decreased in the absence of mineral nutrients in the root zone of buckwheat seedlings.

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 Pb²⁺ and Cd²⁺. Seedlings were grown under controlled conditions in Hoagland nutrient solution, with the addition of low/high Pb²⁺ or Cd²⁺ ions (0.01 and 1.00 mM, respectively). After 3 days of treated seedling growth, the levels of total anthocyanins and content of particular flavonoids were measured. The presence of low concentrations of both Pb²⁺ and Cd²⁺ resulted in a small stimulation of the growth of seedlings of all studied cultivars, while higher doses inhibit root growth and, to a much lesser extent, that of shoots. Cadmium (Cd²⁺) ions were more harmful for growth of buckwheat seedlings than Pb²⁺ ions. More resistant to stress caused by the presence of high concentrations of Pb²⁺ and Cd²⁺ in the growth medium were seedlings of Hruszowska and Luba cultivars, compared to Kora seedlings. Cotyledons of more resistant cultivars (Hruszowska and Luba) contained much more flavonoids than cotyledons of Kora.
