Abstract：Effects of regulated deficit irrigation(RDI)on conformation, activity and dry matter accumulation of maize root were investigated with pot cultivation. Results indicated that RDI may reduce dry matter accumulation to a extent, relevant to seriousness, lasting time of RDI and crop growing stage when RDI treat was carried out.Ratio of root/shoot, TTC contain in root increased, while number and total length of root per seedling decreased. Root activity was improved after re-watering,which suggests that RDI might restrain root growth and development qualitatively, but might improve root absorb performance by improving root activity.
