Development and application of methods used to source prehistoric Southwestern maize: a review

“…In order to extract Sr from these two sources and to avoid extracting Sr from more refractory mineral sources (such as aluminosilicates) we experimented with weak-and dilute-acid soil leaches. Hopi Blue maize grown in experimental gardens at the Crow Canyon Archaeological Research Center at Cortez, Colorado, (Hovezak, 1993) and the New Mexico State University Agricultural Science Center at Los Lunas, New Mexico (Muenchrath, 1995) were obtained from archival collections along with samples of the soil in which they grew.…”

Measuring Maize Seedling Drought Response in Search of Tolerant Germplasm

“…In the case of maize these would ideally be identifiable in inbred lines and inherited to good yielding hybrids. These traits include but are not limited to, shortened anthesis-silking interval (ASI) [9,10], delayed leaf senescence [9], increased rooting depth and density [11], hydraulic lift [12], high leaf number and short plant height [13], performance with limited available nitrogen [14], seedling vigor [15], and epicuticular wax [16,17]. Many secondary trait screening methods are still costly when evaluating large numbers of genotypes in a breeding program.…”

Archaeological Corn from Pueblo Bonito, Chaco Canyon, New Mexico: Dates, Contexts, Sources

“…The results showed that element concentrations are sufficiently distinct to differentiate the fields and the com grown in them (Cordell et al 2001). Two different landraces (genetic varieties, or cultivars) of Native American com (Hopi Blue and Tohono O'Odham 60-day maize) had been planted in the Los Lunas gardens (Muenchrath 1995), providing the additional information that there was no statistical difference in the way each kind of corn processed 15 of 19 elements tested. This was important because if the two landraces had processed many elements differently, then extrapolating to the unknown landraces of archaeological corn would be problematic.…”

“…And finally, they used 87 Sr/ 86 Sr ratios in modern deer mice (Peromyscus maniculatus) to differentiate fields, because mice integrate strontium over a larger surface area than is reflected in point samples of soils taken in association with corn plants. Among the findings reported are that 87 Sr/ 86 Sr ratios in deer mice are not particularly useful for sourcing crops such as Native American landraces of corn, which have roots that tap moisture at depths of more than a meter (Adams 2004;Muenchrath 1995).…”
