Morphological and physiological traits of lotus rhizome at S1 to S3 stages. a-c shows the growth and changes of lotus rhizome size at stage S1, S2 and S3. Bars are 10 cm; and arrows indicate the tissues collected for proteome analysis. d-f represent the PAS staining transverse sections of lotus rhizome at S1, S2 and S3. Bars indicate 100 μm. g shows the starch content (dry weight) and rhizome enlargement index (REI); h shows soluble sugar (dry weight) and water content. Data are means ± se (n = 3)
