  1. T0, control group with no removing-spikelets; T1, removing top 2/3 of the spikelets in panicle; SG, superior spikelets located on all primary branches of rice panicle; IG, inferior spikelets located on all secondary branches of rice panicle; Different letters indicate statistically significant differences under the same year at the P = 0.05 level; The data are the means of three replications ± SD, consisting of 30 plants each
