Purpose. To determine the level of aluminum (Al) accumulation in plants of the Brassicaceae family, which are used in agriculture as green manure and are promising plants for soil phytoremediation. The following crops were the subject of the study: oilseed radish, variety ‘Kyianochka’ (Raphanus sativus L. var oleiformis Pars. ‘Kyianochka’), white mustard, variety ‘Soniachna’ (Sinapis alba L. ‘Soniachna’), winter rapeseed, variety ‘Horlytsia’ (Brassica napus L. ‘Horlytsia’), Sarepta mustard, variety ‘Zolotava’ (Brassica juncea (L.) Czern. ‘Zolotava’), winter turnip rape, variety ‘Oriana’ (Brassica campestris var. oleifera f. biennis D.C. ‘Oriana’), tyfon, variety ‘Fitopal’ (Brassica campestris var. oleifera f. biennis DC. ´ Brassica rapa L. ‘Fitopal’). Methods. The research was carried out in the M. M. Gryshko National Botanical Garden of the National Academy of Sciences of Ukraine (Kyiv). Plants grown as green manure crops for 56 days on grey forest degraded sandy loam soil, pH 6.5–7.0, were analysed. Aluminum content was determined using an inductively coupled plasma optical emission spectrometer (ICPOES) ICAP 6300 Duo. The possibility of metal accumulation in plant tissues was assessed using the bioconcentration factor (BF). Results. Measurements showed the following content of Al in plant tissues (in abs. dry matter): oilseed radish, variety ‘Kyianochka’ – 2035.9 mg/kg, white mustard, variety ‘Soniachna’ – 687.5 mg/kg, winter rapeseed, variety ‘Horlytsia’ – 388.6 mg/kg, Sarepta mustard, variety ‘Zolotava’ – 1238.5 mg/kg, winter turnip rape, variety ‘Oriana’ – 1105.2 mg/kg, tyfon, variety ‘Fitopal’ – 854.4 mg/kg. Conclusions. Under growing conditions, the aluminum content in plants did not exceed 0.2%. All the samples studied have a BF < 1 and are not hyperaccumulators of the element according to this criterion. However, three of the investigated samples (‘Zolotava’ Sarepta mustard, ‘Oriana’ winter turnip rape and ‘Kyianochka’ oilseed radish) have an aluminum content in the aboveground dry matter of more than 1000 mg/kg, indicating a significant accumulation of this element. For the purposes of phytoextraction of aluminum, the most suitable of the plants studied is oilseed radish ‘Kyianochka’ (BF ≈ 0.4). | Мета. Встановити рівень накопичення алюмінію (Аl) у рослинах представників родини Brassicaceae, використовуваних як сидерати у сільському господарстві та перспективних для фіторемедіації ґрунтів. Предметом дослідження були такі культури, як редька олійна [cорт ‘Кияночка’ (Raphanus sativus L. var oleiformis Pars. ‘Kyianochka’)], гірчиця біла [сортозразок ‘Сонячна’ (Sinapis alba L. ‘Soniachna’)], ріпак озимий [сортозразок ‘Горлиця’ (Brassica napus L. ‘Horlytsia’)], гірчиця сарептська [сортозразок ‘Золотава’ (Brassica juncea (L.) Czern. ‘Zolotava’)], суріпиця озима [сорт ‘Оріана’ (Brassica campestris var. oleifera f. biennis D.C. ‘Oriana’)], тифон [сорт ‘Фітопал’ (Brassica campestris var. oleifera f. biennis DC. × Brassica rapa L. ‘Fitopal’)]. Методи. Дослідження проводили в Національному ботанічному саду імені М. М. Гришка НАН України (м. Київ). Рослини, що вирощували як сидерати, аналізували протягом 56 днів на сірому лісовому деградованому супіщаному малогумусному ґрунті, pH 6,5–7,0. Вміст алюмінію визначали, використовуючи оптичний емісійний спектрометр з індуктивно зв’язаною плазмою (ІCPОЕS) ІCAP 6300 Duo. Можливість накопичення металу в тканинах рослин оцінювали за допомогою біоконцентраційного фактора (ВF). Результати. Здійснивши вимірювання, встановили такий вміст Аl у тканинах рослин (у перерахунку на абсолютно суху речовину): редька олійна (сорт ‘Кияночка’) – 2035,9 мг/кг; гірчиця біла (сортозразок ‘Сонячна’) – 687,5; ріпак озимий (сортозразок ‘Горлиця’) – 388,6; гірчиця сарептська (сортозразок ‘Золотава’) – 1238,5; суріпиця озима (сорт ‘Оріана’) – 1105,2; тифон (сорт ‘Фітопал’) – 854,4 мг/кг. Висновки. Вміст алюмінію в рослинах за наявних умов вирощування не перевищував 0,2%. Всі досліджені зразки мали показник BF < 1 та не були гіпернакопичувачами елемента за цим критерієм. Однак сортозразок гірчиці сарептської ‘Золотава’, сорт суріпиці озимої ‘Оріана’ та сорт редьки олійної ‘Кияночка’ продемонстрували значне накопичення алюмінію в наземній сухій масі – понад 1000 мг/кг. Найпридатнішою для фітоекстракції алюмінію серед досліджуваних рослин виявилася редька олійна ‘Кияночка’ (BF ≈ 0,4).

Purpose. To investigate special aspects of accumulation of inorganic elements including heavy metals in seeds of white and black mustard to be grown for obtaining drugs. Methods. Field experiments, microwave digestion, ICP-MS and statistical analysis. Results. The content of inorganic elements including heavy metals was determined in the seeds of white and black mustard grown in Kiev Oblast. It was revealed that during the growing season plants of white mustard were able to accumulate such elements as aluminum, barium, strontium, zinc in seeds in concentrations that exceed their content in black mustard seeds, while compounds of calcium, cesium, iron, magnesium, manganese, potassium in a greater degree were accumulated in black mustard seeds. Conclusions. As legal and regulatory documents for important chemical elements don’t contain the maximum permissible limits of their content in medicinal plants, it would make sense to launch a comprehensive research with the involvement of specialists of relevant profiles in order to establish such a gradation. Plants of white and black mustard in Kiev Oblast have accumulated high levels of such metals as Ba, Cu, Fe, Mn, Mo, Sr, Zn that exceed the known limits of accumulation, indicating a partial contamination of soils in the region. Consequently, these plants can be used for phytoremediation of soils. Considering the fact that in the pharmaceutical practice refined mustard seed oil is used, revealed alterations of metal accumulation in seeds will not affect the quality of the final drugs. According to the research results, white and black mustard is promising for cultivation in Kiev Oblast with a view to obtain raw material that can be processed into drugs.
