Fig. 6From: GC-MS-based metabolite profiling of key differential metabolites between superior and inferior spikelets of rice during the grain filling stageEffects of applied trehalose (A) and sucrose (B) on the contents of fructose, glucose, sucrose, and trehalose of inferior spikelets (IS). Data in the figure are means and SD of four independent measurements. Asterisks represent significant difference (**P < 0.01)Back to article page
