Abstract:

To clarify the difference of photosynthetic and grain-filling characteristics of maize varieties in different ages in response to increasing planting density, and to provide a theoretical basis for the reasonable density and production of maize, in this study, five maize varieties planted in large areas during production from 1970s to 2010s in China were used as materials, two planting densities of 45,000 plants hm-2 and 105,000 plants hm-2 were set for three-year field experiment. The yield and its components, leaf photosynthetic performance, and grain filling characteristics of maize varieties in different years were compared and analyzed under different planting densities. The results showed that under low planting density, compared with varieties of 1970s-2000s, the SPAD value of ear-leaf after anthesis, Pn of ear-leaf at 50 d after anthesis, and the average grain filling rate of 2010s varieties (DH618) were significantly increased by 2.18-12.05, 0.57-4.88 μmol CO2 m-2 s-1, and 0.02-0.09 g kernel-1 d-1. The active grain-filling period was significantly prolonged by 2.62-4.74 d, which significantly increasing grain weight and yield at P<0.05. After densification, the yield of varieties in 1970s and 1980s decreased, the yield of varieties in the 1990s did not change significantly, but the yield of varieties in 2000s and 2010s increased significantly and the largest increased in 2010s was 2.11 t hm-2. Further correlation analysis to the indicators of photosynthetic performance, filling characteristics, 100-grain weight, and yield, the results showed that 100-grain weight of 2010s varieties under high planting density was more dependent during active grain filling period (r = 0.70). Compared with 1970s to 2000s, the 2010s varieties kept relatively high SPAD at silking stage, milking stage, and maturity stage (increased by 6.42%-41.92%), delayed leaf senescence and maintained high LAD in maize leaves after anthesis and Pn in 30-50 d after anthesis (increased by 1.09%-88.95%). Therefore, more photosynthates were accumulated, which prolonged the active grain filling period by 8.73% to 15.80% and the average filling rate increased by 3.39% to 24.33%, and then maintained a relatively stable 100-grain weight.

Key words: maize, varieties of different eras, planting density, grain filling characteristics, canopy configuration
