“…Poaceae: large pollen grains, macroremains and their chronological trend By considering morphology, macroremains and archaeological contexts, the large Poaceae pollen found in the spectra may reliably be attributed to some genera including wild cereals: Panicum, and Setaria and Echinochloa having the very large pollen (see Section 4.4). Thus, the large pollen helped to recognise, within the Poaceae, some wild cereals that are known to have always been largely collected for food and fodder in Africa nowadays (Harlan, 1989;Stemler, 1980;Williams and Farias, 1972).…”

“…Established plants may survive for several years without rain (Batanouny, 2002). Panicum turgidum is economically important because of its use as a sand binder, as a forage plant in arid areas and as a source of grains (Williams and Farias, 1972). Lasiurus scindicus Henrard is another drought‐tolerant, highly nutritious grass (Chowdhury et al.…”

The grasses Lasiurus scindicus and Panicum turgidum are among the most important forage species of the Arabian deserts. Both are 'glycophytic' or salt-intolerant species, where seed germination becomes reduced by salinity effects. Here, we report experimental effects of light ⁄ darkness, temperature and NaCl salinity on seed germination and 'recovery' germination in these two species, after seeds had been transferred from saline solution to distilled water. Seeds were germinated in a range of salinities and incubated at a range of temperatures, in both light and darkness. Seeds of P. turgidum germinated significantly more in darkness than in light at temperatures 15-25°C, but the reverse was true at higher temperatures. Seeds of L. scindicus germinated well across a wide range of temperatures and in both light and darkness. In both species, germination decreased with the increase in salt concentration, and in P. turgidum germination was almost completely inhibited at a concentration of 200 mM M . In saline solution, germination in darkness was significantly greater than in light at all the temperatures. Seeds of both species 'recovered' their germination capacity after transfer from saline solutions to distilled water. Germination recovery depended on both light and temperature of incubation in both species.

“…The noncrop priorities included forage grasses and woody species (IBPGIURoyal Botanic Garden, Kew 1984) in the following genera: Andropogon; Cenchrus; other species of Pennisetum not in the primary gene pool of pearl millet; Stylosanthes; Panicum (Naegeler 1977;Williams & Farias 1972) (Table 2); and Acacia (Celles & Maniere 1980;Hutchinson & Dalziel 1954;von Maydell 1983) (Table 3). Other species that hold promise as semi-arid forage were also included.…”

Multi–gene‐pool Surveys in Areas with Rapid Genetic Erosion: An Example from the Aïr Mountains, Northern Niger

A survey to sample and document wild and cultivated plants with crop and forage genetic resources was carried out in the Aïr Mountains of northern Niger in 1984, 1985, and 1986. This ecogeographical survey was begun in the 1984 drought after considerable desertification had already occurred. Over the last century in this area, there has been progressive alteration and loss of habitat and populations, with probable genetic erosion. The focus was on wild and weedy species in the following gene pools: Pennisetum, Sorghum, Olea, Andropogon, Cenchrus, Brachiaria, Eragrostis, Panicum, Setaria, Acacia, Ziziphus, and Grewia; and on crops from irrigated gardens, including pearl millet, sorghum, and barley. Due to the high degree of environmental heterogeneity and the loss of habitat, relativity small numbers of individuals and clumps were identified a significant portion were probably part of previously contiguous occurrences. In this type of setting, surveys of rapidly diminishing crop and forage genetic resources are especially needed A basis for identifying strategies for sampling and monitoring as species ecology and successional and cultural factors is outlined.
