Effect of heavy metals on mycorrhization roots of legume-¬rhizobia symbiosystems of <i>Pisum sativum</i> L.

The influence of amicrobial consortium consisting of the nodule bacteriumRhizobiumleguminosarumbv.viciaestrainCIAM1079, the associative rhizobacteriumVariovorax paradoxusstrain 5C-2 and the arbuscular fungusGlomussp. 1Fo was studied. on the biomass of roots and the formation of mycorrhizal infection in various genotypes of peas grown on fallow sod-podzolic soil contaminated with heavy metals.It was shown that artificial inoculation of plants on average contributed to an increase in mycorrhization parameters by about 4 times.At the same time, in most cases, this practically did not affect the intensity of growth of the root system of plants against the background of soil contamination with toxicants.The use of the neural network data analysis method showed that morphometric indicators were not areliable criterion for assessing the degree of mycorrhization of amacrosymbiont.The calculation of cognitive significance indices provided aprerequisite for the creation of aprogram for assessing the ecochemical processes underlying the integral interaction of symbiotic partners in conditions of multiple symbiosis and the stressful influence of environmental factors.
