comparative study on the natural occurrence of fusarium mycotoxins (trichothecenes and zearalenone) in corn and wheat from high- and low-risk areas for human esophageal cancer in china.	a comparative study on the natural occurrence of fusarium toxins was done with 47 corn and 30 wheat samples collected in 1989 from linxian and shangqiu counties in henan province, people's republic of china, high- and low-risk areas, respectively, for esophageal cancer. three trichothecenes (deoxynivalenol [don], 15-acetyldeoxynivalenol [15-adon], and nivalenol [niv]) and zearalenone (zea) were detected in corn samples, and don, niv, and zea were found in wheat samples. compared with shangqiu co ...	1990	2150585
fumonisin occurrence in corn from high- and low-risk areas for human esophageal cancer in china.	forty-seven corn samples were collected in 1989 from linxian and shangqiu counties in henan province, the high- and low-risk areas, respectively, for human esophageal cancer in the people's republic of china. the samples were analyzed for fumonisin (fumonisin b1 [fb1] and fb2) contamination. of the fumonisin-positive samples, the mean levels in linxian corn were found to be 872 ng/g for fb1 and 448 ng/g for fb2, while the shangqiu corns had 890 ng of fb1 and 330 ng of fb2 per g. the incidence of ...	1994	8017941
evaluation of the natural refuge function for helicoverpa arnigera (lepidoptera: noctuidae) within bacillus thuringiensis transgenic cotton growing areas in north china.	the density of helicoverpa armigera (hübner) populations on bacillus thuringiensis berliner (bt) transgenic cotton, corn, peanut, and soybean; differences in its development on bt cotton and common (nontransgenic) cotton; and the potential for mating among populations from bt cotton fields and other crop fields were investigated in the suburbs of xinxiang city (henan province) and langfang city (hebei province) in the southern and northern parts of north china, respectively. although development ...	2002	12216828
complete nucleotide sequence of a potyvirus causing maize dwarf mosaic disease in central china.	the full-length nucleotide sequence of a potyvirus causing the maize dwarf mosaic (mdm) disease in henan province, central china, was obtained by reverse transcription-polymerase chain reaction (rt-pcr) and rapid amplification of the cdna 5'-end (5'-race). the viral genome comprised of 9596 nucleotides except the polya tail and encoded a putative polyprotein of 3603 amino acids. the entire genomic sequence of this isolate shared identities of 94.2% and 98.3% with sugarcane mosaic virus (scmv) hz ...	2003	15068377
nitrous oxide emissions from an intensively cultivated maize-wheat rotation soil in the north china plain.	n2o emissions from a maize-wheat rotation field were monitored in the fengqiu state key agro-ecological experimental station (fengqiu county, henan province, china) from june 2004 to june 2005. the experiment included four treatments: a bare (crop-absent) soil treated with 150 kg n ha-1 (wn150) and soils fertilized with 0 (n0), 150 (n150), and 250 (n250) kg n ha-1 and cropped with maize or wheat. the bulk of the n2o emissions occurred in pulses following the application of fertilizer n at soil t ...	2007	17229455
