Physiological and transcriptomic analyses to reveal underlying phenolic acid action in consecutive monoculture problem of Polygonatum odoratum

Table 4 Soil enzyme activities in FC and CC rhizosphere soil

Rhizosphere soil sample	PPO (mg/d/g)	CAT (μmol/d/g)	UE (μg/d/g)	ACP (μmol/d/g)	SC (mg/d/g)
FC	49.269 ± 0.438	17.867 ± 1.022	392.069 ± 32.173^a	22.871 ± 0.830	34.800 ± 0.188^a
CC	47.727 ± 0.688	17.284 ± 1.026	298.174 ± 14.843	22.004 ± 0.321	20.801 ± 0.177

Note: values were expressed as mean ± standard error, and ^a was marked for the significant difference within the same column with the T-Student’s method (P < 0.05, n = 3). FC stands for first cropping, and CC stands for continuous cropping. PPO stands for polyphenol oxidase, CAT stands for catalase, UE stands for urease, ACP stands for acid phosphatase, and SC stands for sucrase
