Macronutrient and sodium content in maize plants under cassava wastewater fertilization

Directed Fertilization in Maize.

Analysis of nuclear DNA content in monosomic maize plants

Five maize monosomics were analyzed for their nuclear DNA content. Several hundred seeds of R/r-X1 X mutants were grown for two weeks and monosomics with missing chromosomes were identified based on their mutant phenotypic characteristics. Nuclei were isolated from both normal and monosomic two-week old seedlings, and stained with 4,6-diamidino-2-phenylindole (DAPI) and propidium iodide (PI) fl...

Stem perimeter, height and biomass of maize (Zea mays L.) grown under different N fertilization regimes in Beijing, China

In this study, nitrogen fertilizer was applied to corn (Zea mays L.) at conventional (excessive) and recommended levels, and the growth response was assessed by measuring plant height and stem perimeter. Corn plant maximum height was observed in recommended rates of N fertilizer treatment, and the height without N fertilizer was the same as that receiving excess N fertilizer. Stem perimeter was...

1 Institute of Soil and Environmental Sciences, University of Agriculture, Faisalabad, Pakistan 2 Department of Soil Science, College of Food and Agricultural Sciences, King Saud University, Riyadh, Kingdom of Saudi Arabia ABSTRACT. A pot experiment in wire house was conducted to investigate the effect of potassium fertilization on physiology, growth and nutrient uptake of maize. Surface soil s...

In Vitro Fertilization with Isolated, Single Gametes Results in Zygotic Embryogenesis and Fertile Maize Plants.

We demonstrate here the possibility of regenerating phenotypically normal, fertile maize plants via in vitro fertilization of isolated, single sperm and egg cells mediated by electrofusion. The technique leads to the highly efficient formation of polar zygotes, globular structures, proembryos, and transition-phase embryos and to the formation of plants from individually cultured fusion products...
