Quantitative evaluation of protocorm growth and fungal colonization in Bletilla striata (Orchidaceae) reveals less-productive symbiosis with a non-native symbiotic fungus

Quantitative evaluation of symbiotic cells in Pecteilis radiata protocorm. (a) Symbiotic cells with hyphal coils in P. radiata protocorm. Scale bars, 50 Οm. (b) Ratio of the number of symbiotic cells at each stage in a symbiotic protocorm. Each value represents the average number of symbiotic cells in ten protocorms. The experiments were repeated six times with similar results. (PDF 959 kb

Quantitative evaluation of symbiotic cells in a protocorm under conditions with high concentrations of oatmeal. (a) The number of symbiotic cells per one protocorm under 2×- and 4×-strength oatmeal conditions for four weeks after seeding. (b) Ratio of the number of symbiotic cells at each stage in a symbiotic protocorm under 2×- and 4×-strength oatmeal conditions. Error bars represents the standard error of the mean in ten protocorms. The experiments were repeated three times with similar results. (PDF 140 kb
