Plant Introduction| Резюме: | Our investigations prove that the size, the allocation and the kinetic peculiarities of the root system are the important factors, affecting on the process of nutrient uptake from substratum. It’s worth noting that the process of nutrient uptake causes the decreasing of the mineral substances close to the root system. The moving of the compounds below the absorbing zone in the process of mass flow is followed by disbalance, inducing the concentration gradient. Subsequent rapid conversion of the nutrients from the solid phase into solution leads to the increasing their inflow for the root system. The prolongation of this process results in the formation of the certain concentration profile, which depends on the solution kinetics in the substrate, directly on the diffusion and convection mechanisms as well as on the transport rate near the roots. |
