Abstract
Three popcorn varieties were used in this experiment,yield ear trait and quality were researched in five different plant densities.The results showed that in the denstity of 525000plants/hm2 to 825000plants/hm2,the yield of the three varieties all increased straightly with the increasing of density,yield in the highest desity of the three varieties is 4567.9-5596.0kg/hm2,higher 12.8%、8.4% and 20.2%than the the desity of 600000plants/hm2;With the increasing of density,that is with the increasing of ear number,rows per ear、kernels per row、100- kernel weight、ear diameter and ear length all reduced,however the extent were all small;With the increasing of density,shelling percentage changed like a parabola,the value was the biggest when the desity was 600000plants/hm2,while it would be smaller when the density was higher;Particle size grade rate of popcorn and palatability of the three varieties would not be influenced with the increasing of density,exploded multiples would increased obviously with the increasing of density,while the popcorn shape would not;With the increasing of density,starch percentage increased and protein percentage decreased,while the extent were all small,oil percentage almost had no change.
