Fig. 8From: Culturable endophytic fungi community structure isolated from Codonopsis pilosula roots and effect of season and geographic location on their structuresCorrelation analysis. a MantelTest between soil physics and chemistry and species abundance. Different colored lines indicate different P values, Different color rectangles represent different correlations. The agronomic characters of C. pilosula were measured by root length (RL), root diameter (RD) and root weight (RW). polysaccharide content revealed the relationship between soil physics and chemistry and the accumulation of active components of C. pilosula. b Distribution of culturable endophytic fungi in roots of C. pilosula and their plots. Abbreviations in all figures have the following meanings. TN: Total nitrogen content in soil, AN: Content of available nitrogen in soil, TK: Total potassium content in soi, AK: Content of available potassium in soil, AP: Content of available phosphorus in soil, EC: Electroconductibility, H: Altitude, PRO: Protease, URE: Urease, CAT: Catalase, SUC: SucraseBack to article page
