چکیده مقاله:
In order to investigate the influence of sulfur coated seeds in SCS (a moisture absorbent polymer layer on seeds) on physiological traits of cotton, a field experiment was conducted in completely randomized design with factorial arrangement with 3 replications. Three planting date included early (E), optimum (O), and delayed (D) planting time. Seed coating priming treatments consisted of F (fuzzy seeds, control), FS (fuzzy seeds with SCS), FSS (fuzzy seeds with sulfur coating and SCS), D (delinted seeds), DS (delinted seeds with SCS), DSS (delinted seeds with sulfur coating and SCS). Findings showed that the effects of planting date and seed coating treatments on chlorophyll, anthocyanin, proline, and glycine betaine content were significant. Interaction of treatments of seed coating and planting date treatments showed that treatments of seeds with ED, EDS, ODS and DDSS, had the highest content of chlorophyll. EFSS treated seedlings had the highest content of anthocyanin (0.58 mg g-1Fw) which increased with treatments application while anthocyanin content decreased in EDS and EDSS treatments, in comparison with ED. The highest (0.76 mg g-1Fw) and lowest (0.21 mg g-1Fw) concentrations of anthocyanins were recorded when F seeds were planted at optimum date (OF) and delayed (DF) planting dates, respectively. In three planting date treatments of ED (8.82 µg g-1Fw), OFS (8.83 µg g-1Fw), and DDS (9.37 µg g-1Fw), the highest proline content was obtained. In early planting treatments, glycine betaine content decreased in all coating treatments. ED and EDS treatments had lowest glycine betaine content. Treatments of seed coating in optimum and delayed dates of planting resulted in identical amounts of glycine betaine production.

Seed cotton yield and fiber qualities may be significantly altered by a number of agronomic practices. The present study investigates the effect of nitrogen levels on cotton cultivar's seed cotton yield and fiber quality traits. Three cotton cultivars (NIAB-111, CIM496 and FH901) were tested against four nitrogen levels (0, 60, 120 and 180 kg ha) to check reliability, the highest yielding and g...

Making use of the markers linked closely to QTL for early-maturing traits for MAS (Marker-assisted selection) is an effective method for the simultaneous improvement of early maturity and other properties in cotton. In this study, two F2 populations and their F2:3 families were generated from the two upland cotton (Gossypium hirsutum L.) crosses, Baimian2 × TM-1 and Baimian2 × CIR12. QTL for ea...

Cotton is one of the most important commercial crops in India, playing a key role in national economy. Short duration and high yielding varieties are always required for better quality and lint production. Early maturing crops avoid disease and pest epidemics due to which plant breeders have positioned adequate pressure on the development of early maturing crop plants (Singh, 2004). Term earlin...

Segregating populations were developed to evaluate the inheritance of the fuzzless seed phenotypes in upland cotton (Gossypium hirsutum L.). Accession 143 of the Mississippi Obsolete Variety Collection (MOVC) has a fuzzless seed phenotype. This line carries the n(2) locus which is recessive to the seed fuzz phenotype. Data from the F(2), BC(1)F(1), F(2:3), and BC(1)F(2) populations of DP 5690 x...
