Agricultural crops experience diverse mechanical stimuli, which may affect their growth and development. This study was conducted to investigate the effects of mechanical stresses caused by hanging labels from the flower petioles (HLFP) on plant shape and cotton yields in four cotton varieties: CCRI 41, DP 99B, CCRC 21, and BAI 1. HLFP significantly reduced plant height by between 7.8% and 36.5...

Impact of hybridization and irradiation in isolation of superior segregants in four crosses of desi cotton were studied and compared between F2 and F2M2 progenies. The F2M2 progenies of four crosses recorded higher per cent of superior segregants compared to F2 progenies for boll number, boll weight and halo length excepting in KS-16 x MB-3200 cross. Out of four F2M2 progenies, RDC-53 x 9747 cr...

The cotton genus (Gossypium) provides a superior system for the study of diversification, genome evolution, polyploidization, and human-mediated selection. To gain insight into phenotypic diversification in cotton seeds, we conducted coexpression network analysis of developing seeds from diploid and allopolyploid cotton species and explored network properties. Key network modules and functional...

Cotton (Gossypium spp.) fiber cells are seed trichomes derived from the epidermal layer of the cotton seed coat. The molecular components responsible for regulating fiber cell differentiation have not been fully elucidated. A cotton PROTODERMAL FACTOR1 gene (GbPDF1) was found to be expressed preferentially during fiber initiation and early elongation, with highest accumulation in fiber cells 5 ...

The slow diffusion of new technology in the agricultural sector in less developed countries has long been a puzzle to development economists. While most of the current empirical research on technology adoption focuses on credit constraints and learning spillovers, this paper examines the role of individual risk attitudes in the decision to adopt a new form of agricultural biotechnology in China...

Cotton fibers are single-celled extensions of the seed epidermis. They can be isolated in pure form as they undergo staged differentiation including primary cell wall synthesis during elongation and nearly pure cellulose synthesis during secondary wall thickening. This combination of features supports clear interpretation of data about cell walls and cellulose synthesis in the context of high t...

Twelve field experiments and one laboratory experiment were conducted to determine the effects of furrow applied aldicarb and seed treatments of thiamethoxam, imidacloprid, Avicta (thiamethoxam + abamectin), Aeris (imidacloprid + thiodicarb), and acephate on twospotted spider mite, Tetranychus urticae Koch, on cotton, Cossypium hirsutum L. For the field experiments, data were pooled across all ...

The research objective for production of quality cottonseed that has been a major concern of cottonseed researchers for many years is to: "Identify the genetic variability of cottonseed composition, determine the genetic control of cottonseed traits, and develop preferred cotton· seed quality germplasm; develop an understanding of developmental processes of the plant that leads to improved cott...

This paper compares the profitability and cost of production of irrigated Roundup Ready cotton varieties and conventional cotton varieties grown under crop share rental agreements in the Texas High Plains Region for 1998. The Standardized Performance Analysis (SPA) program was used to analyze 25 sub-enterprises for each variety type from six producers selected from the regional SPA database for...

Naturally occurring polyamines in plants have been implicated in cell division, metabolic activity, floral initiation, and fruit development. The plant growth regulator BM was formulated to stimulate seed production and fruit growth. In this study, it was hypothesized that the addition of BM would increase levels of polyamines for seed induction and have a direct benefit of improving fertilizat...
