TABLE 3.

Soil enzymatic activity in the three konjac growing sites affected by different levels of soft rot disease.

Site	Sucrase activity	Urease activity	Catalase activity	Polyphenol oxidase activity
	(mg⋅g–1⋅day–1)	(μg⋅g–1⋅day–1)	(μmol⋅g–1⋅day–1)	(mg⋅g–1⋅day–1)
ND	5.52 ± 0.01b	14.84 ± 0.17a	1.43 ± 0.11a	99.67 ± 0.42a
MD	5.62 ± 0.02a	7.57 ± 0.10b	1.07 ± 0.05b	50.50 ± 0.38b
HD	4.58 ± 0.01c	6.17 ± 0.13c	0.91 ± 0.09b	36.75 ± 0.57c

ND, MD, and HD represent the non-diseased, moderately diseased, and highly diseased konjac stands infected by soft rot disease, respectively. Values are means ± standard deviation (n = 3). Means followed by different letter are significantly different [p ≤ 0.05; least significant difference (LSD) test].
