Natural occurrence of vesicular-arbuscular mycorrhizal (VAM) fungi in Chinese jujube trees was investigated in Zanhuang, Gaoyi, Wangdu county and the garden of Hebei Agricultural University. The results showed that VAM fungi were present on all the trees but the percentage infection varied with locality, variety and the age of the trees. The older the trees, were the higher the percentage infection bacame. The trees planted in both fertile and sterile soil had lower percentage infection.
