Abstract: To intense the planting density of maize is one of the key factors to increase yield potential. However, higher planting density would take a risk of maize lodging, which may decrease yield and quality of maize with machine harvest problems. The jointing-booting stage is susceptible to lodging in maize, thus a field experiment was conducted to investigate root and shoot characteristics associated with resistance to strong wind- and rain-induced lodging. The results showed that experimental maize was with a heavy lodging. Root lodging was more frequently than shoot lodging, accounting for 90.4% and 4.9% of the total, respectively. As for root lodging, major was with middle and heavy lodging rather than light lodging. Compared with lodging maize, lodging resistant maize was with wider diameter of base internodes, higher moment of inertia and section modulus bending; also, lodging resistant maize was with more nodal roots and stronger root maximum tension in higher internodes.
