Biosorption of lead by maize (Zea mays) stalk sponge
Journal of Environmental Management, 2010This study investigated the removal of Pb(II) from aqueous solutions by a maize (Zea mays) stalk sponge. Equilibrium and kinetic models for Pb(II) sorption were developed by considering the effect of the contact time and concentration at the optimum pH of 6 +/- 0.2. The Freundlich model was found to describe the sorption energetics of Pb(II) by Z. mays

MORPHOLOGY OF TEOSINTOID AND TRIPSACOID MAIZE (ZEA MAYS L.)
American Journal of Botany, 1978Modern races of maize (Zea mays L.) are characterized by indurated glume and rachis tissues. The archaeological record, as well as experimental studies indicate that in North America this induration is associated with hybridization between domesticated maize and its closest wild relative Z. mays subsp. mexicana (Schrad.) Iltis (teosinte).

Methods in molecular biology (Clifton, N.J.), 2006
Agrobacterium tumefaciens-mediated transformation is an effective method for introducing genes into maize. In this chapter, we describe a detailed protocol for genetic transformation of the maize genotype Hi II. Our starting plant material is immature embryos cocultivated with an Agrobacterium strain carrying a standard binary vector.

Improved anther culture of maize (Zea mays)
Plant Science Letters, 1981Abstract Culture of anthers of maize hybrids Dan-San 91, King Hwang 13 and Coe's inbred stock 6 in vitro was attampted. Dan-San 91 repeatedly performed efficiently; approx. 17% of the inoculated anthers of this hybrid on the average responded positively to culturing.

Nutrient removal by weeds and maize (Zea mays)
Indian Journal of Agronomy, 2001Maize (Zea mays L.) is one of the most influenced by different weed-management important grain crops grown in Andlira practices. The weeds under unweeded check Pradesh with an average yield of 1,700 kg1 recorded the highest uptake of NPK ha compared with national average of 1,474 nutrients on account of higher weed dry kglha.

Sampling Maize (Zea mays) Seed Endophytes
Cold Spring Harbor ProtocolsFor most farmers, the production of maize grain is the ultimate goal of the entire field season. From the point of view of plant microbiome studies, seeds are particularly interesting in that they are the only avenue for vertical transmission of microbes from parent to offspring, though microbes can also enter maize seeds via wounds or silks.

The Use of Selection Indices in Maize (Zea mays L.)
1977Estimates of genetic variances for yield and its components—ear number, kernel rows, kernels per row, and kernel weight—and genetic covariances among them were computed for a synthetic population of maize, using 100 S5 lines randomly chosen out of a lot developed from the population with a minimum of selection.

Gametophyte Transformation in Maize (Zea mays, Gramineae)
1986Genetic transformation, with or without living biological systems has been achieved with several species of higher plants. The most efficient living delivery system is the Ti plasmid of Agrobacterium tumefaciens. It functions as a gene transfer vector in a range of dicotyledoneous taxa (Horsch et al.
