Bletilla striata protocorms in symbiotic and asymbiotic culture. a B. striata protocorms cultured on oatmeal ager medium with symbiotic fungus HR1-1 (Symbiotic protocorm) and on Hyponex agar medium without the symbiotic fungus (Asymbiotic protocorm). Images were collected every week for 4 weeks. Scale bars, 500 μm. b The length and width of symbiotic and asymbiotic protocorms. Filled circles and squares indicate length (L) and width (W), respectively. Solid and broken lines represent symbiotic and asymbiotic protocorms, respectively. Error bars represent the standard errors of the mean of five replicates
