“…The report of Bischoff and Koch (1973) also supports that best germination occurs in slightly acidic soils. Similar results were also obtained by Brown et al (1965) and Johnson et al (1976) in O. minor in which seed germination was inhibited by the alkaline solution but retarded in the acidic medium. The study suggests that application of agricultural lime in the acidic field might help to reduce Orobanche problem to some extent.…”

In order to investigate effect of soil moisture, Orobanche seeds were pre-conditioned in three different soil moisture conditions. The germination percentage was found to be highest (48.31%) in normal soil moisture condition and lowest (4.6%) in flooded soil moisture condition. This indicates that Orobanche seeds are unable to survive for a long period in water logged conditions. In response to stimulant pH, Orobanche solmsii seeds showed significantly a high germination percentage (65.27%) at pH value 6.5 and it declined progressively with the increase of acidic and alkaline conditions. However, seeds appeared to be more sensitive to alkaline rather than acidic condition. The study of effect of light showed that exposure of seeds to continuous light during pre and postconditioning period inhibited seed germination. The inhibition was more effective when seeds were exposed to light during post conditioning phase rather than during pre-conditioning phase.

“…On reviewing these findings, and in the light of this study on H. sessilis, we conclude that in all probability the first leaf primordium had been mistaken for the dome-shaped plumule. Besides podostemads, there are several other angiosperms, such as Utricularia, Orobanche, Cistanche, and orchids, in which mature embryos are unorganized and lack cotyledons and/or differentiation of apical meristems (Brown 1965;Mohan Ram and Dore Swamy 1966;Arditti 1967;Kumazawa 1967;Rangaswamy 1967). However, in some of these plants, roots and/or shoots develop during germination.…”

“…The seeds of S. asiatica require a period of conditioning in moist warm environment for 7-14 days in the dark, before they have the potential to germinate (Brown 1965;Hsiao et al 1981Hsiao et al , 1987. However, they will not germinate after conditioning unless they are exposed to natural germination stimulants released from roots of host or non-host plants (Brown 1965;Musselman 1987;Yokota et al 1998).…”

“…However, they will not germinate after conditioning unless they are exposed to natural germination stimulants released from roots of host or non-host plants (Brown 1965;Musselman 1987;Yokota et al 1998). Formation or activation of receptors for germination stimulants, leaching of germination inhibitors, increase in seed-coat permeability and biosynthesis of plant hormones that play important roles in germination are some of the events that may occur during conditioning of seeds (Brown and Edwards 1944;Kust 1963;Brown 1965;Visser 1989;Worsham and Egley 1990;Joel et al 1995).…”

Inhibitors of carotenoid biosynthesis are known to prevent abscisic acid (ABA) biosynthesis and to affect germination and dormancy of seeds in many plants. In this study, the effects of three carotenoid biosynthesis inhibitors, fluridone, norflurazon and diflufenican, on the conditioning and germination of Striga asiatica seeds were examined. Fluridone and norflurazon shortened the conditioning period required before S. asiatica seeds would germinate after exposure to the germination stimulant strigol, and prevented the inhibitory effects of both light and supraoptimal temperature (40°C) on seed germination. In addition, treatment with fluridone or norflurazon after conditioning in water induced seed germination in a manner similar to the effect of natural germination stimulants. Moreover, the seedlings developing after conditioned with fluridone formed haustorium-like structures without the involvement of haustorium inducing factors. In contrast, diflufenican had no effect on the conditioning and germination of S. asiatica seeds. These results indicate that fluridone and norflurazon have various effects on the germination of S. asiatica seeds and might be available for control of root parasites.
