Fig. 4From: Improved node culture methods for rapid vegetative propagation of switchgrass (Panicum virgatum L.)Shoot induction efficiency of the GWAS population. a Three representative genotypes showing diverse shoot induction efficiency. b Distribution in shoot induction efficiency of the GWAS population. c Comparison of the axillary bud rate and shoot induction rate in 11 genotypes. Data were collected from 8 to 18 node samples per genotype. d Presence or absence of axillary buds in representative genotypes. Scale bar: 1 mmBack to article page
