INFLUENCE OF ARBUSCULAR MYCORRHIZAL FUNGIES AND A NATIVE DIAZOTROPHIC BACTERIA IN SURVIVAL AND TUBERIZATION OF EX VITRO POTATO PLANTS

The inoculation of several species of micropropagated plantlets with native diazotrophic bacteria and arbuscular mycorrhizal fungi has been reported to increase growth and survival percentage compared to plantlets without inoculation. The survival of in vitro developed potato (Solarium tuberosum L....
