“…A similar decline to low levels has also been reported for imbibed, non-germinating seeds of non-parasitic plants (Barton 1945;Ibrahim et al 1983). Also like some non-parasitic plants (Roberts 1973;Roberts and Smith 1977), respiration prior to germination is at least in part via the cyanide-insensitive respiratory pathway, but this happens in the parasite seeds during early conditioning (Bar-Nun et al 2003).…”

“…Seeds can survive, imbibed, in the soil for long periods (Crocker, 1916) yet respiration rates of such seeds can be appreciable (Barton, 1945), adding support to the theory that seeds in soil tnay eventually die due to exhaustion of food reserves (Crocker, 1916). The rate of respiration found for non-dormant calabrese seeds held under moisture stress in polyethylene glycol solution seemed to be cotnpatible with survival for a long period before the seeds' reserves would have been exhausted (Hegarty, 1977a).…”

Current interest in seed hydration treattnents for the improvement of level, rate and uniformity of gennination or field emergence has revealed how little is Imown of the physiology of getmination control under water stress. This review surveys briefly the responses of seeds held at different hydration levels, from normal germination in a free water supply to seed activation without germination under slight moisture stress, seed deterioration at greater moisture stress and the damage that can be caused to seeds in very dry conditions, as well as the responses to subsequent dehydration. Inhibition of germination, though not of seed activation, at certain levels of water stress is likened to various forms of dormancy, and the mechanism governing the initiation of cell elongation is suggested as the possible key to control over germination. Several lines of evidence on cell membrane integrity and action, and their responses to external factors, point to tlie role that the membrane may play in cell elongation (and hence germination) eontrol, and membrane integrity may also be associated with the transition between seed deterioration at one hydration level and seed activation and repair at slightly higher hydration levels. Seed activation witliout germination is also considered in an ecological context.

“…Differences among seed lots in dormancy characteristics often diminish with the length of time in dry storage (Barton 1945;Schonbeck and Egley 1980a;ChadoeufHannel andBarralis 1982b, 1983). Schonbeck and Egley (1980a) reported that seeds of A. retroflexus kept in dry storage for two years at -20ºC germinated 0-2% at temperatures lower than 30ºC and 40-65% at 39.5ºC.…”

The three species are noxious weeds introduced to Canada from southern North America. Their geographical distribution has remained almost unchanged since the original paper published in 1980. The plants exhibit a high phenotypic plasticity and genetic variability and they easily adapt to a multitude of agrestal and ruderal habitats. The seeds contribute to a persistent seed bank; they exhibit a variable dormancy and polymorph germination as a result of maternal, genetic and environmental factors. Growth is rapid and plants produce a large number of viable seeds. The three species have developed multiple resistance to triazine and acetolactate-synthase-inhibiting herbicides. They are alternate hosts to many insects, nematodes, viruses, bacteria and fungi that affect cultivated plants.
