Fig. 1From: GC-MS-based metabolite profiling of key differential metabolites between superior and inferior spikelets of rice during the grain filling stageGrain-filling processes of superior spikelets (SS) and inferior spikelets (IS) of rice. A Developmental changes in representative SS and IS. B Grain weight of SS and IS. C Grain-filling rate of SS and IS. D Starch accumulation of SS and IS. The grain-filling rate was calculated according to Richards’ equation. Data in figures B, C and D are means and SD. of six independent measurementsBack to article page
