Fig. 2From: The Elite Alleles of OsSPL4 Regulate Grain Size and Increase Grain Yield in RiceGrain phenotypes of the OsSPL4 mutation transgenic lines and control plants. A Grain shapes of spl4-d3, spl4-d15 and control plants, scale bar = 1 cm. B–G Comparisons of grain size and the yield between spl4-d3, spl4-d15 and control plants. B Grain length. C Grain width. D Grain thickness. E Grain bulk density. F 1000-grain weight. G Grain yield per plant. Significant difference was determined by Student’s t test, *P < 0.05, **P < 0.01Back to article page
