Data on percentage germination and haustorial initiation were calculated for each disc, transformed to arcsine and subjected to analysis of variance (ANOVA).
Definitive haustorial connections were observed on two of the twelve C.
The effects of bacterial isolates on haustorial initiation varied from non- significant to significant when compared with the nutrient broth medium.
The sorghum host participates in the parasitic association with striga at many levels: exuding the stimulant for striga seed germination, providing the haustorial initiation signal, allowing penetration to its vasculature and producing assimilates and possibly other factors in forms usable by the parasite.
In addition, at any one time, these parasites can have numerous, fairly transitory haustorial connections, and thus they are likely to attach to more than one host species simultaneously (Atsatt and Strong 1970, Gibson and Watkinson 1989).
Haustorial frequency of some root parasites in culture.
Data on percentage germination, haustorial initiation and attachment were calculated and subjected to analysis of variance (ANOVA) [7].
The EAGA, on the other hand, allows observation of haustorial attachment and expression of HR events post-attachment following ethylene treatment, in addition to striga germination.
In addition to the introduction to parasitic plants by Musselman and Press, the book consists of ten chapters that fall within five general areas: haustorial development, physiology, reproductive biology, genetics, and agronomy.
Some families have specialised structures in this region; for example, in the dicot family Podostemonaceae there is a nucellar plasmodium, which is a multinucleate haustorial protoplast (Arekal & Nagendran, 1975).
Butler (1995) observed that sorghum genotypes showed wide differences in their capacity to produce germination stimulant, but relatively little variability in their capacity to produce haustorial initiation factor, and that the inheritance of these traits was completely independent.
Several species in the Scrophulariaceae family are root hemiparasites, meaning that the plants are capable of robbing nutrients, water, and even organic compounds from their hosts through haustorial root connections (e.g., Press et al.
