Relative proportions of the three classified stages of parasite development observed in rhizotron bioassays

Treatment (n = 10)	% seeds germinated (± s.e.)	% seedlings attached (± s.e.)	% tubercles (± s.e.)
O. minor ssp. maritima on sea carrot	59·35 ± 3·43	0·87 ± 0·30	0
O. minor var. minor on sea carrot	60·56 ± 3·50	3·29 ± 1·05	0·22 ± 0·16
O. minor ssp. maritima on red clover	4·80 ± 1·99	0	0
O. minor var. minor on red clover	28·10 ± 7·23	1·17 ± 0·43	0

Values are expressed as a percentage of the total number of seeds counted.

Measurements were taken 30 d after inoculation.
