Avena sativa

Decreasing the Copper Ion Phytotoxicity Using Rhodococcus Biosurfactants

Authors: Litvinenko L. V., Tishchenko A. V., Ivshina I. B.

The effect of copper on the germination of seeds of several agricultural plants, namely, common vetch, white mustard and oats in the presence of Rhodoccocus-biosurfactants was studied. As a result of the conducted studies it was established that Avena sativa L. was the most stable plant to the action of copper, and Vicia sativa L. was a less stable plant. By the copper resistance degree, the plants used in the work could be arranged in the series: Avena sativa L. > Sinapis alba L. > Vicia sativa L.

Pb AND Cd INFLUENCE ON BIOCHEMICAL INDICES OF AVENA SATIVA (POÁCEAE, LILIOPSIDA)

Authors: Petukhov A. S., Khritokhin N. A., Petukhova G. A., Kremleva T. A.

This work is devoted to studying of changes of vegetable raw under Pb and Cd translocation in the tissues of oat grown on turf and sand soils at model pollution, as well the impact of Pb and Cd accumulation on the biochemical status of plants. The oat germinants accumulated the intriduced metals actively; at a combined action of Pb and Cd, synergism of the elements in the organogenic soil and antagonism in the mineral soil were revealed.
