Correlation analysis of phenotypic traits, pseudobulb weight and active ingredient contents. Correlation analysis of phenotypic traits, pseudobulb weight and main active ingredient contents in 2018 (a), 2019 (b) and 2020 (c) was carried out. Values are Pearson correlation coefficients, which are used to construct the heat map. * or ** represent a significant difference with the parameters of P < 0.05 and P < 0.01, respectively
