on
Mar 27, 2019
ABSTRACT Verticillium wilt is a major problem in many cotton producing countries. In addition to causing big losses in yield, deterioration in fiber quality affects the commercial value of cotton. This study was undertaken to determine the damage caused in fiber quality characters by various degrees of Verticillium wilt infection. Four commercial...
Fiber Property Variability from Bale to Bale
By

on
Mar 27, 2019
ABSTRACT Cotton (Gossypium hirsutum) fiber variability at the bale level is a composite of fiber properties contributed by individual bolls. Environmental conditions, crop management and genotype have an impact on fiber property variability at the boll and seed level. Cotton plants (DPL 51, 1995; NuCOTN 33B, 1996) were grown under rainfed (RF) and...
Variability of Cotton Fiber Quality
By

on
Mar 27, 2019
ABSTRACT Fiber quality variability is one of the key determinants of the profitability of the cotton crop. As variability increases, the risk associated with production increases and the expected return decreases. Prior to this study, variability had been characterized at the field or crop level. New technologies permit the analysis of very small...

Mar 27, 2019
ABSTRACT Cotton stickiness is a serious problem for many producing countries. In Sudan, 1000 bales of the 1996 production WERE selected and sampled to study the feasibility of a bale stickiness classification. Sixteen thousand samples tested on the Sticky Cotton Thermodetector show that within-bale variance increases with the mean. Statistical inv...

ABSTRACT Stickiness in cotton is a serious problem confronting both producers and users. The major causative agent of cotton lint stickiness is the honeydew excreted by the insects whitefly and aphid. The sugar constituents of the honeydew are the reducing monosaccharides glucose and fructose and the non-reducing oligosaccharides sucrose and melez...

Mar 22, 2019
ABSTRACT Sticky cotton caused by insect honeydew contamination is a major issue in the cotton industry. Bemisia tabaci (Gennadius) Strain B (= B. argentifolii Bellows and Perring) honeydew contributes to cotton lint stickiness. Increases in thermodetector sticky cotton counts and trehalulose and melezitose were correlated to increasing Bemisia nym...
