TABLE 1.

Profile of three konjac growing sites in the study.

Site	Altitude/m	Canopy	Slope	Average plant	Soil	Annual average	Planting	Incidence of	Disease
		closure/%		height/cm	texture	precipitation/mm	density/m2	soft rot/%	index
ND	1,043	60	32°	85.5	Brown clay	1,033	6.25	0	0
MD	963	58	29°	82.7	Brown clay	1,033	5.56	4.2	1.4
HD	995	57	30°	81.8	Brown clay	1,033	6.25	18.6	18.6

ND, MD, and HD represent the non-diseased, moderately diseased, and highly diseased konjac stands infected by soft rot disease, respectively.
