The Effect of Compound Preparation Made by Ectomycorrhizal Fungus and Hormone on the Growth and Disease Resistance of Poplar Cuttings

The authous studied the efttct of compound preparation made by ectomycorrhizal fungus and hormone on the growth and disease resistance of poplar cuttings. The results showed that the compound preparation could accelerate the growth of the poplar cuttings, because the amount of absorbing root, mycorrihizal infectin rate and ratio of root and stem were enhanced. Meanwhile, the compound preparation could accelerate the growth of the other part of the cuttings, because the cutting survival rate, height, diamete, biomass, content of chlorophyll and capacitance were increased. Finally, the compound preparation could enhance the disease resistance of poplar cuttings, because the RT, activity of POD and polyphenolase and PAL were increased. The IBA solution could also accelerate the growth of cuttings, but the effect was not as good as that of compound preparation.
