The allelotoxicity influence of 12 samples of Great Russian Plain soils on the seed germination of different cultivars of spring wheat was assessed. Based on the obtained data it is concluded that the effect of biologically active substances (BAS) on seed germination is due, on the one hand, to the content of these substances in the soils, and on the other hand, to the various content in seeds of BAS required for their development. The supposition about the existence of a common mechanism to protect the seed from the negative influence of soil allelotoxins is made. |
