Vent were studied in this experiment based on scanner-based image analysis. The results showed that drought and AM inoculation had a large, significant effect on plant development. Biomass, total length, surface area, volume, number of root nodes, average diameter and fractal dimension of root system in Broussonetia papyrifera Vent decreased with the reduction of soil moisture, while they were increased by AM inoculation. Special root length in non-AM plants increased when soil moisture was reducing, but it was decreased by AM inoculation.
