Spike Traits and Yield of Maize Treated by Different Chemical Regulators

Abstract

Abstract: The aim was to find the optimum chemical regulators for different maize varieties. Six maize varieties were used as the principal factor, and treatments of five chemical regulators were used as the secondary factor. The effects of different chemical regulators on the spike traits and yield of maize were studied with randomized block design. Ten spikes were selected randomly in every block. The spike traits were detected, and the grain yield was converted into the population yield. The results showed that for the same variety, CCC had significant effect on the spike traits compared with other chemical regulators. Gaoyujin were not suitable for chemical regulating on tested varieties. Yield was proportional to axle thickness, spike thickness and kernels per row. In addition, spike weight, spike grain weight and spike length were closely related to the population yield of maize under different treatments, and hundred-grain weight had the minimum impact on the yield.‘Xieyu 5’was fit for improving the spike traits with chemical regulators. So different chemical regulators should be adopted according to different maize varieties, no chemical regulator could satisfy all maize varieties.
