Glomus deserticola Trappe, Bloss and Menge, one of the most commonly o
ccuring VAM fungi of arid and semiarid regions, was cultured and multi
plied in root organ cultures of Ziziphus nummularia under in vitro con
ditions. The In vitro produced VAM fungi established efficient symbios
is with in vitro raised plantlets of Z. nummularia.. This VAM strain i
mproved the biomass production, nutrient uptake, and acclimatization o
f the in vitro produced plantlets of Z. nummularia in pots under green
house conditions.
