↵ySum of cross-sectional area at the perimeter of the root ball of roots in each root diameter class.
↵xMeans in a row followed by different letters are significantly different fromeach other by Duncan’s Multiple Range Test, p < 0.05. There were no differences among treatments in any other root-diameter classes.
