Fig. 1. Striga development at the vicinity of sorghum roots. (a) Three days after infection to detect germination stimulant production; (b) Two days after ethylene treatment to detect haustorial initiation activity. (1) Wild accession PQ-434, (2) cv. CK60 (high germination stimulant sorghum). Bar = 1 mm. Arrows in b2 point to haustoria.

Fig. 2. Mean maximum germination distance (MGD) measured in Exp. 3. Bars represent the mean of each accession ± one standard deviation (n = 11). Letters above bars indicate significance groups; means sharing the same letter are not significantly different (p < 0.008).

Fig. 3. Mean percent germination of Striga asiatica seed measured in Exp. 3 before and after ethylene treatment. Values for the plate without sorghum were taken from ten randomly selected 6 mm fields across each of two plates. There was no germination on these plates for the first count made at 3 d (before ethylene). Germination counts for sorghums were taken within 3 mm of the main root. Bars represent the mean of each accession ± one standard deviation (n = 11). Letters above bars indicate significance groups; means sharing the same letter are not significantly different (p < 0.008).

Fig. 4. Mean maximum haustorial distance (MHD) measured in Exp. 3. Bars represent the mean of each accession ± one standard deviation (n = 11). Letters above bars indicate significance groups; means sharing the same letter are not significantly different (p < 0.008).

Fig. 5. Mean percent of germinated Striga asiatica seed with haustoria measured in Exp. 3. Haustoria counts were taken within 3 mm of the main root. Bars represent the mean of each accession ± one standard deviation (n = 11). Letters above bars indicate significance groups; means sharing the same letter are not significantly different (p < 0.008).
