В отдельных экспериментах изучали воздействие лантана на длину корней и колеоптилей проростков ячменя. Показано, что La3+ способен эффективно угнетать рост корешка при концентрации в растворе выше 10 мг/л и одновременно стимулировать рост колеоптиля при концентрации выше 50 мг/л. В вегетационном опыте отмечено значимое накопление лантана в листьях и стеблях, начиная с концентрации внесенного в почву лантана 20 и 50 мг/кг соответственно, отмечено значимо большее накопление лантана листьями, чем стеблями. Обнаружено значимое уменьшение содержания хлорофиллов и каротиноидов в варианте с внесением 100 мг/кг лантана по сравнению с контролем и накопление надземной биомассы при концентрации внесенного лантана 100-200 мг/кг. Накопление биомассы, обнаруженное в вегетационном опыте, согласуется со стимулирующим влиянием лантана на удлинение колеоптиля проростков, что, учитывая одновременное уменьшение длины корешка, может объясняться гормональными процессами. Полученные результаты могут быть полезны для переоценки безопасности применения редкоземельных элементов в сельском хозяйстве и для установления влияния лантана на биохимические процессы в растениях.</p></abstract><trans-abstract xml:lang="en"><p>In conditions of the vegetation experiment with barley under the artificial illumination, we assessed the ability of lanthanum, which is one of the most widely spread lanthanons, to accumulate in leaves and stems of plants. Also we assessed its ability to affect the elemental composition, biomass and chlorophyll and carotinoides content of plants. The separate studies allowed us to investigate the impact of lanthanum on root length and coleoptiles of barley seedlings. It is shown that La3+ is able to depress significantly the growth of rootlet if its concentration will exceed 10 mg/l and simultaneously stimulate the growth of coleoptile at the concentration exceeding 50 mg/l. The vegetation experiment showed the significant accumulation of lanthanum in the leaves and stems beginning from the exceeding the concentration of 20 and 50 mg/kg of lanthanum within the soil. It is marked that the accumulation of lanthanum in leaves is higher than in stems. The significant decrease of the chlorophyll and carotinoides in the variant with the implementation of 100 mg/kg of lanthanum comparing to the control and the accumulation of ground biomass at the concentration of the implemented lanthanumof 100-200 mg/kg. Theaccumulationofbiomass, whichwasrevealed in the vegetation experiment, correlates with the stimulating impact of lanthanum on the elongation of coleoptile. Taking into account the simultaneous decrease of the root length, the elongation of coleoptile may be explained by the hormonal process. The results obtained may be useful for re-assessment of the security of the implementation of lanthanons in agriculture and the impact of lanthanum on the biochemical processes in plants.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лантан</kwd><kwd>поглощение</kwd><kwd>биохимия</kwd><kwd>токсичность</kwd><kwd>lanthanum</kwd><kwd>consumption</kwd><kwd>biochemistry</kwd><kwd>toxicity</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Pochinok Kh.N.
