Abstract:

The coordination of shoot and root is essential for the growth and development in maize. Analyzing the effect of the planting density on the shoot and root coordinated development can provide a new perspective for the theory and technology of increasing planting density and yield improvement. The experiments were conducted in 2020 and 2021 at the experimental station of Institute of Crop Sciences, the Chinese Academy of Agricultural Sciences, Gongzhuling, Jilin province. Two densification resistant varieties (Zhengdan 958 and Xianyu 335) and two planting densities (D1: 67,500 plants hm-2; D2: 97,500 plants hm-2) which were in the production stability interval were set up in this study, and the difference of some indexes of root and shoot was analyzed at different growth stages. The results showed that, compared with D2, the dry matter and root dry weight per plant of maize decreased significantly, while some population indexes were different. Among them, the yield of two varieties were not significantly increased. When the root indexes reached the maximum value on the 15th day after silking (R2 stage), the root dry weight per area, root length density did not increase significantly. The dynamic of shoot root ratio (S/R) during growth period could be expressed by exponential equation (y=aebx), and the increasing planting density significantly increased the S/R, grain root ratio, and leaf area root ratio. The increase of the three ratio at high density provided a signal of intensified root survival pressure. The results showed that the response of maize root to planting density was different from that of shoot. Under the premise of the same yield level, choosing the planting density with less root pressure may be more conducive to the construction of shoot and root coordination and constructing reasonable maize population.

Key words: maize, reasonable dense planting, yield, root dry weight, shoot root coordination
