Figure 9

Correlation between bending resistance, branch angle, composition, and spike structure in different positions. ((A–C) The bending resistance of different parts is correlated with the structure and composition of microtubule bundles; (D) Correlation analysis between branch angle and panicle structure at different panicle positions). RS: stem bending resistance, RSs: rachis bending resistance; RLPP: bending resistance of the lower primary branch. LMS: stem diameter, BP: panicle node diameter, LPB: lower primary branch diameter, LNS: large vascular bundles of stem, LSS: small vascular bundles of stem, LNLPP: large vascular bundles of the lower primary branch, LSLPP: small vascular bundles of the lower primary branch, CS: stem cellulose, CSs: rachis cellulose, CPB: primary branch cellulose, LCS: stem lignin, LCSs: rachis lignin, LCPB: primary branch lignin, RUPP: upper primary branch stem bending resistance, RCPP: the bending resistance of the central primary branch, RLPP: bending resistance of the lower primary branch, SsLB: area of large vascular bundles in rachis, SsSB: area of small vascular bundles in rachis, AU: angle of the primary branch for upper panicle, LSLPP: number of small vascular bundles in primary branch, LPPLB: large vascular bundle area of primary branch, LPPSB: small vascular bundle area of primary branch. AM: angle of the primary branch for middle panicle; AL: angle of the primary branch for lower panicle. * and ** represent significant levels of 0.05 and 0.01, respectively.
