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.

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.
Although visual examination of haustorial connections between parasites and hosts indicates the possibility that a parasite is attacking a particular host, parasitic plants will form haustoria on dead plant material or even pebbles (Piehl 1963), making it unclear whether a particular haustorium is in fact functional.
A single infected sorghum root showed reddening at most but not all haustorial attachment sites.
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.
Absence of a haustorial inducer in root exudate is an improbable resistance mechanism since the haustorial inducer 2,6-dimethoxy-parabenzoquinone is thought to be produced by all plants under striga attack (Frick et al.
aphyllus is one of the most highly reduced seed plants known (Mauseth 1990); the inflorescence is the only plant part to emerge from the host; the rest of the plant exists as an endophytic haustorial system without roots, leaves, or vegetative stems.
