Abstract:
... Substitution of wheat (Triticum aestivum L.) chromosomes 7A, 1D, 3A, 3B, 3D, 4A and 4D of cultivar Cappelle Desprez by their homologues of cultivar Bezostaya-1 increased the seedling tolerance to high concentrations of copper (1 μM CuSO₄⋅ 5 H₂O). Substitution of chromosome 1A had negative effects on seedling tolerance. ...

Cowpea (Vigna sinensis L.) plants were inoculated with arbuscular mycorrhizal fungus (Acaulospora laevis) to investigate the effects of different concentrations of di-n-butyl phthalate (DBP; 0, 10, and 100 mg kg⁻¹) added to soil on their growth. Mycorrhizal plants were less affected by high concentration of DBP (100 mg kg⁻¹) than non-mycorrhizal ones. Also the uptake and transformation of DBP by m ...
