Phenotypic plasticity and plant resistance to abiotic stress

Abstract

The phenotypic plasticity of cultivated plants exceeds that characteristic of spontaneous plants. Concerning this, the question arises as to why a commensurate level of genome volume did not accompany the high level of crop plant phenotype changes. More and more data are emerging, demonstrating that, due to the rapid activation of phylogenetic adaptation systems stored in the genome, phenotypic plasticity generates non-random adaptation changes. We present the results of assessing the resistance of plants to the action of extreme temperatures and the influence of the biostimulator Reglalg on the viability, resistance, plasticity, and productivity of wheat and pedunculated oak plants.
