[1] New images from the Lunar Reconnaissance Orbiter Camera show the distribution and geological relations of the Sculptured Hills, a geological unit widespread in the highlands between the Serenitatis and Crisium basins. The Sculptured Hills shows knobby, undulating, radially textured, and plains-like morphologies and in many places is indistinguishable from the similarly knobby Alpes Formatio...

BACKGROUND AND AIMS Physiological epicotyl dormancy in which the epicotyl elongates inside the seed before the shoot emerges has been reported for only a few tropical rainforest species, all of which are trees that produce recalcitrant seeds. In studies on seeds of Fabaceae in Sri Lanka, we observed a considerable time delay in shoot emergence following root emergence in seeds of the introduced...

ABSTRACT Resistance to Striga hermonthica in 274 wild Pennisetum glaucum subsp. monodii and stenostachyum accessions was evaluated at Samanko, Mali in 1997 and 1998, and at Cinzana, Mali and Sadoré, Niger in 1998. Data recorded included number of striga plants per plot at least three times during the season, date of striga emergence, number of Pennisetum plants, Pennisetum anthesis date, and do...

assessment of different plant genetic resources clarifies genetic variation and makes it possible to apply them in plant breeding programs. in this experiment, 27 selected lines of common bean (phaseolus vulgaris l.), one local landrace and two conventional bean cultivars (talash and cos-16 as controls), sown using randomized complete block design with three replications in the research farm of...

We quantified the duration and phenology of remigial molt of Barrow’s Goldeneyes (Bucephala islandica) in northwestern Alberta, Canada. We estimated that the remiges’ average (± SE) growth rate was 3.94 ± 0.13 mm day–1, slightly slower than that of most waterfowl. Barrow’s Goldeneyes regained flight with the ninth primary 77% grown, a percentage similar to or greater than that of most waterfowl...
