Fig. 5From: GC-MS-based metabolite profiling of key differential metabolites between superior and inferior spikelets of rice during the grain filling stageEffects of applied sucrose and trehalose on the 1000-grain weight and seed setting rate of superior spikelets (SS) and inferior spikelets (IS). Data in the figure are means and SD of four independent measurements. Asterisks represent significant difference (*P < 0.05, **P < 0.01)Back to article page
