1. Human ventilatory response to washed and unwashed cottons from different growing areas.

Thirty volunteer subjects were exposed to controlled amounts of respirable dust generated by the carding of cotton in an experimental cardroom. Eighteen exposures each lasting six hours were performed while carding unwashed and washed cottons from the three major growing regions of the United States. Elutriated dust was analysed gravimetrically and was compa

2. Interaction of Boron with Components of Nucleic Acid Metabolism in Cotton Ovules Cultured in Vitro

Cotton (Gossypium hirsutum L.) ovules grown in a defined nutrient medium undergo normal morphogenesis, including fiber production. In identical medium lacking boron, ovules callus and accumulate brown substances. Boron deficiency-like symptoms were induced by 6-azauracil and 6-azauridine in ovules growing in boron-sufficient media. Other nucleoside base anal

4. Phenotypic variability among isolates of Ramularia areola from Brazilian cotton

There is a lack of information about the level of resistance of cotton genotypes to a wider range of Ramularia areola isolates occurring across the cotton growing areas of Brazil. For this purpose, firstly it is necessary to know the existence or not of genotypic and phenotypic variability among the R. areola isolates from different geographical origins. The

5. The Manganese Toxicity of Cotton 1

Cotton plants (Gossypium hirsutum. Linn. var. Sankar 4) were grown at normal and toxic levels of substrate manganese, and the altered metabolism of manganese toxic plants was studied. The tissues of plants exposed to toxic levels of manganese had higher activities of peroxidase and polyphenol oxidase, and the activities of catalase, ascorbic acid oxidase, gl

6. USING PASSIVE AND ACTIVE MULTISPECTRAL SENSORS ON THE CORRELATION WITH THE PHENOLOGICAL INDICES OF COTTON

ABSTRACT: The investment in precision agriculture technologies has been growing as well the investment in vegetation index sensors with different types of data collection. This study aimed to evaluate the NDVI potential use obtained from passive and active multispectral sensors as phenological parameters indicator of cotton growth. The experiment was conduct

7. Bacteria on closed-boll and commercially harvested cotton.

The bacterial content of specially treated cottons used by other investigators to test human pulmonary responses to cotton dust was examined. Cotton from Lubbock, Tex. and Stoneville, Miss. were either (i) harvested by machine and handled as commercial bale cotton, (ii) harvested as closed bolls with bracts intact and opened under special conditions, (iii) h

9. Infection process of Phakopsora gossypii in cotton leaves

ABSTRACT Tropical rust caused by the biotrophic fungus Phakopsora gossypii is an emerging disease in cotton that has caused significant yield losses of crop/cotton cultivated in Brazil. Considering the current importance of tropical rust and the need to obtain additional basic information about its causal agent to better control this disease, the present stu

10. Ascorbate peroxidase. A prominent membrane protein in oilseed glyoxysomes.

The glyoxysomes of growing oilseed seedlings produce H2O2, a reactive oxygen species, during the beta-oxidation of lipids stored in the cotyledons. An expression library of dark-grown cotton (Gossypium hirsutm L.) cotyledons was screened with antibodies that recognized a 31-kD glyoxysomal membrane polypeptide. A full-length cDNA clone (1258 bp) was isolated

11. Estabilidade fenotípica de genótipos de algodoeiros obtidos por semigamia no Estado de Minas Gerais

The objectives of this research were: to evaluate the performance of doublehaploid cotton genotypes (HD) in relation to their parental genotypes in three contrasting environments of the state of Minas Gerais, Brazil, and to determine the possible genotype by environment interactions and stability and adaptability parameters. In the state of Minas Gerais, Bra

Resumo A cochonilha Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) é uma praga de algodão, amplamente, difundida em várias regiões produtoras do Brasil, particularmente, na região semiárida do sudoeste da Bahia. O impacto do caulim na sobrevivência, desenvolvimento e reprodução de P. solenopsis foi avaliado em laboratório. O delineament
