The development of Aspergillus flavus inoculation techniques has played an important part in developing corn (Zea mays L.) germplasm resistant to aflatoxin contamination. Corn genotypes evaluated for aflatoxin resistance in field studies must be artificially inoculated due to the sporadic nature of aflatoxin contamination from year to year. A number of different inoculation techniques are used ...

In this study, the mutagenic effects of low power radiofrequency radiation on Zea mays root tip were studied. Cells in different division phases and chromosomal aberration assay were used to determine the mitotic index and chromosomal aberration frequency of Zea mays root tip cells induced by 900MHz radiofrequency radiation. Zea mays seeds, having a uniform genophond, have been exposed to RF fi...

The article presents the results of studies one main crops modern world agriculture, common corn (Zea mays L.) Daniil variety. It is a culture versatile use and high productivity.Compared to wheat rice, corn, from point view its application, probably most diverse cereal crop.During research, same conditions temperature, humidity lighting were created in different containers. Germinated seeds pl...

Accelerator mass spectrometry age determinations of maize cobs (Zea mays L.) from Guilá Naquitz Cave in Oaxaca, Mexico, produced dates of 5,400 carbon-14 years before the present (about 6,250 calendar years ago), making those cobs the oldest in the Americas. Macrofossils and phytoliths characteristic of wild and domesticated Zea fruits are absent from older strata from the site, although Zea po...

Aboveground and belowground interactions are crucial in the over-yielding of intercropping systems. However, relative effects aboveground on yields maize (Zea mays L.) soybean (Glycine max) systems still unclear. Field experiments, including measurements plant height, soil-plant analysis development (SPAD) value, photosynthetically active radiation (PAR), root length density (RLD), volume (RVD)...

Choice tests were conducted to determine feeding preferences of European corn borer, Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae), neonates for 15 species of plants. Percentage of neonates accepting (found on) each leaf disc after 24 h was measured using choice tests. Initially, nine species of plants were evaluated. The following year, 10 plant species were evaluated during O. nubilali...

In New York, the primary coccinellid in corn and sweet corn (Zea mays, L.) has historically beenColeomegillamaculata (DeGeer).However,Harmonia axyridis (Pallas)has alsobeen observed the last few years. The objectives of this study were to document the level of establishment of both species in corn and sweet corn and to understand their interactions. The temporal and within-plant distributions o...
