a

Gall index = severity of root galling by M. hapla assessed on a 0–5 rating scale according to the percentage of galled tissue in which 0 = 0–10% of galled roots, 1 = 11–20%, 2 = 21–50%, 3 = 51–80%, 4 = 81–90%, and 5 = 91–100% (Barker, 1985).

b

CE = control effect.

c

Egg mass index was assigned to each count using a rating of 0 = no egg mass, 1 = 1–3 egg masses, 2 = 4–10 egg masses, 3 = 11–30 egg masses, 4 = 31–100 egg masses, and 5 = >100 egg masses per root system (Roberts et al., 1990).

d

Averages ± standard deviations of five replications followed by the same letters are not significantly different at P ≤ 0.05 by the least significance difference (LSD) test.
