Efficacy of three rates of aldicarb for control of Hoplolaimus columbus was evaluated on highly tolerant ('Foster'), moderately tolerant ('Coker 368'), and highly susceptible ('Braxton') soybean cultivars planted on 28 June 1985. Average yields of the nontreated cultivars were 557 kg/ha for Braxton, 1,309 kg/ha for Coker 368, and 1,682 kg/ha for Foster. Yield differences were significant. Aldic...

Miniature inverted-repeat transposable elements (MITEs) are ubiquitous in high eukaryotic genomes. More than 178,000 MITE sequences of 338 families are present in the genome of rice (Oryza sativa) cultivar Nipponbare. Interestingly, only two of the 338 MITE families have homologous sequences in the genome of Brachypodium distachyon, a relative in the grass family. Therefore, the vast majority o...

Nanostructure of water-soluble pectin (WSP) and chelate-soluble pectin (CSP) of two Chinese cherry (Prunus pseudocerasus L.) cultivars (soft cultivar 'Caode' and crisp cultivar 'Bende') with two different ripening stages were characterised using atomic force microscopy. Both cultivars shared some common values of chain widths for WSP or CSP, and both pectins shared several values of chain width...

The number of transgenic cotton cultivars available for commercial production has increased greatly in recent years. Cotton producers now have multiple choices when choosing transgenic cotton cultivars. The choice of cultivar now dictates the insect and weed control programs that will or can be used. It is estimated that, in 2002, 55% of Arkansas’ cotton acreage was planted to a stacked-gene cu...

This list of the North American vegetable cultivars was developed using the database of cultivars registered with the American Seed Trade Association, as well as published descriptions from scientific journals, seed catalogs, and websites of seed companies. Assistant editors responsible for each crop were instructed to obtain as much information as possible about the cultivars available to Nort...

Field experiments were conducted in 2012 and 2013 during drought conditions in South Texas and the Texas High Plains to test whether cotton water-deficit stress, age, and cultivars are moderating and interacting factors that affect cotton fleahopper, Pseudatomoscelis seriatus (Reuter) (Hemiptera: Miridae), abundance and yield loss. Irrigation and sequential plantings of several cultivars were u...

The effect of water deficit on carbohydrate status and enzymes of carbohydrate metabolism (alpha and beta amylases, sucrose phosphate synthase, sucrose synthase, acid and alkaline invertases) in wheat (Triticum aestivum L.) was investigated in the seedlings of drought-sensitive (PBW 343) and drought-tolerant (C 306) cultivars. The water deficit was induced by adding 6% mannitol (water potential...

Inoculation of plant pathogenic bacteria in field plots has been improved by the use of organosilicone surfactants. Factors, such as cultivars, number of applications, crop stage, plant density, concentration of bacteria, and irrigation application method (overhead spray versus drop hoses), that may affect field screening of cotton cultivars for resistance to bacterial blight caused by Xanthomo...

A sand culture experiment was conducted to answer the question whether or not exogenous KNO(3) can alleviate adverse effects of salt stress in winter wheat by monitoring plant growth, K(+)/Na(+) accumulation and the activity of some antioxidant enzymes. Seeds of two wheat cultivars (CVs), DK961 (salt-tolerant) and JN17 (salt-sensitive), were planted in sandboxes and controls germinated and rais...

Drought stress induced pollen sterility is a detrimental factor reducing grain number in wheat. Exploring the mechanisms underlying pollen fertility under drought conditions could assist breeding high-yielding wheat cultivars with stress tolerance. Here, by using two Chinese wheat cultivars subjected to different levels of polyethylene glycol (PEG)-induced drought stress, possible links between...
