Influence of Phytophthora parasitica var. nicotianae cystospores with rapeseed roots.

Treatments	Cystospore rupture rate (%)a	Cystospore germination rate (%)b	Percentage of germ tube growth towards the root (%)b
Roots	8.14 ± 2.59**	33.84 ± 10.46**	46.11 ± 9.26**
Capillary tube	0.21 ± 0.21	1.56 ± 0.79	18.59 ± 9.59

^aThe cystospore rupture rate was calculated at 30 min after zoospores exposure to root

^bThe cystospore germination rate and percentage of germ tube growth towards the root were recorded at 120 min after zoospores exposure to root.

Double asterisks (**) indicate statistically significant differences (Student’s t-test; p < 0.01; n = 15).
