| bioethanol production from dedicated energy crops and residues in arkansas, usa. | globally, one of the major technologic goals is to achieve cost-effective lignocellulosic ethanol production from biomass feedstocks. lignocellulosic biomass of four dedicated energy crops [giant reed (arundo donax l.), elephantgrass (pennisetum purpureum (schumach), miscanthus × giganteus (illinois clone), and (clone q42641) {hybrid of miscanthus sinensis anderss. and miscanthus sacchariflorus (maxim)}, hack. called giant miscanthus, and sugarcane clone us 84-1028 (saccharum l. spp. hybrid)] an ... | 2011 | 21086455 |
| mapping qtl main and interaction influences on milling quality in elite us rice germplasm. | rice (oryza sativa l.) head-rice yield (hr) is a key export and domestic quality trait whose genetic control is poorly understood. with the goal of identifying genomic regions influencing hr, quantitative-trait-locus (qtl) mapping was carried out for quality-related traits in recombinant inbred lines (rils) derived from crosses of common parent cypress, a high-hr us japonica cultivar, with rt0034, a low-hr indica line (129 rils) and lagrue, a low-hr japonica cultivar (298 rils), grown in two us ... | 2011 | 20857082 |
| nutritionally important starch fractions of rice cultivars grown in southern united states. | dietary starches can be classified into 3 major fractions according to in vitro digestibility as rapidly digestible (rds), slowly digestible (sds), and resistant starch (rs). literature indicates that sds and/or rs have significant implications on human health, particularly glucose metabolism, diabetes management, colon cancer prevention, mental performance, and satiety. in this study, the nutritionally important starch fractions (rds, sds, and rs) in cooked rice were assayed in vitro, making us ... | 2010 | 20629878 |
| residual concentrations of propanil, tcab, and other pesticides in rice-growing of soils in the united states, 1972. | ninety-nine soil samples from the rice-growing states of arkansas, california, louisiana, mississippi, and texas were collected, primarily to monitor the herbicide propanil. no residual concentrations of propanil were detected in any of these samples, but tcab, a propanil transformation product, was detected in six samples at concentrations ranging from 0.01 ppm to 0.05 ppm. organochlorine and organphosphorus pesticide determinations were also performed. the compounds dieldrin, aldrin, and ddt a ... | 1980 | 7422467 |
| impact of volunteer rice infestation on yield and grain quality of rice. | volunteer rice (oryza sativa l.) grains may differ in physicochemical traits from cultivated rice, which may reduce the quality of harvested rice grain. to evaluate the effect of volunteer rice on cultivated rice, fields were surveyed in arkansas in 2012. | 2017 | 27328627 |
| variation in grain arsenic assessed in a diverse panel of rice (oryza sativa) grown in multiple sites. | • inorganic arsenic (as(i) ) in rice (oryza sativa) grains is a possible threat to human health, with risk being strongly linked to total dietary rice consumption and consumed rice as(i) content. this study aimed to identify the range and stability of genetic variation in grain arsenic (as) in rice. • six field trials were conducted (one each in bangladesh and china, two in arkansas, usa over 2 yr, and two in texas, usa comparing flooded and nonflood treatments) on a large number of common rice ... | 2011 | 22142234 |
| the impact of herbicide-resistant rice technology on phenotypic diversity and population structure of united states weedy rice. | the use of herbicide-resistant (hr) clearfield rice (oryza sativa) to control weedy rice has increased in the past 12 years to constitute about 60% of rice acreage in arkansas, where most u.s. rice is grown. to assess the impact of hr cultivated rice on the herbicide resistance and population structure of weedy rice, weedy samples were collected from commercial fields with a history of clearfield rice. panicles from each weedy type were harvested and tested for resistance to imazethapyr. the maj ... | 2014 | 25122473 |
