Bacterial isolates in combination with carboydrates (used as substrate) increased the efficacy of microorganisms in reducing germination and haustoria of Striga.

DMBQ and root macerate applied to Striga germlings resulting from seeds previously conditioned in water and treated with GR24 induced 49 and 40% haustoria, respectively (Table 10).
When dodder seeds germinate in spring, thin, yellowish stems twine around whatever plants they touch, extracting water and nutrients from them through rootlike haustoria (food-absorbing growths).
To determine the maximum haustorial initiation distance (MHD), the radicles of germinated striga were examined for the presence of hair-like projections characteristic of haustoria. Ignoring the basal 2 cm of sorghum root, distances from haustoria to the sorghum root were measured to the nearest 0.5 mm.
Indeed, in many cases, the mycobiont extends tiny tubes called haustoria deep into the photobiont cells, to obtain a continual sugar supply.
Fruit loculicidal to septicidal capsules, berries, drupes (with 1 or several pits), or occasionally dry and indehiscent; seeds small, testa usually single layered, with cells isodiametric to strongly elongated, sometimes winged or tailed, sometimes mucilaginous on wetting; embryo fusiform or spatulate, white or less commonly green, with 2 cotyledons, to extremely reduced and undifferentiated; endosperm cellular, well developed, with haustoria at both ends; germination epigeal.
