The tested environmental variables included Soluble Pro, proteins; LMW, low-molecular weight carbohydrates; HMW, high-molecular weight carbohydrates; Aa, total free amino acids; plant total nitrogen; C, carbon; P, phosphorus; C/N ratio; and N/P ratio. Pearson's correlation coefficients (r) are shown.

^*P < 0.05.
