Inoculation efficiency of Glomus intraradices and intrapopulation variability in plants of Medicago lupulina L. on productivity and forming of mycorrhiza

On the background of low content of available phosphorus in soil the authors estimate the intrapopulation polymorphism of two wild population and two varietal populations of Medicago lupulina on productivity and activity of mycorrizal forming. It was shown that among studied alfalfa forms the individual plants have high-efficient symbiosis with Glomus intraradices, and the Pav-lovskaya wild population is of interest as a source of genotypes contrasting on this characteristic.
