EFFECTS OF LOW TEMPERATURE ON PHYSIOLOGICAL MECHANISMS OF COTTON FIBER STRENGTH FORMING PROCESS Low-temperature responses of enzyme activities related to fiber development of two cotton (Gossypium hirsutum L.) cultivars with different temperature-sensitivity. Effects of nitrogen concentration in subtending leaves of boll on related enzymes and strength formation of cotton fiber Effects of Nighttime Temperature Increase at the Late Growth Stage on the Cotton Fiber Yield and Fiber Strength in Xinjiang Effects of Exogenous Substances on Fiber Strengths of the Bolls Growing on Different Fruiting Shoots of Cotton Plants under Low Temperature Circumstances THE DEPOSITION OF CELLULOSE AND CORRELATION WITH FIBERSTRENGTH IN COTTON Pyramid Breeding by Marker-assisted Recurrent Selection in Upland Cotton Activity Changes for Enzymes Associated with Fiber Development and Relation with Fiber Specific Strength in Two Cotton Cultivars Investigation of cotton mega-environment based on fiberstrength selection and GGE biplot Effect of Hormone on the Super-molecular Structure and Strength of Cotton Fiber Effects of Exogenous and Physiologically Active Substances on the Development of Cotton Bolls at Low Temperature Activity Changes and Expression Profiles of Sus with Relation to Fiber Strength in Island Cotton (Gossypium barbadense L.) Genotypic Differences in Cellulose Accumulation of Cotton Fiber and Its Relationship with Fiber Strength Sugar Metabolism and its Relationship with Fiber Strength Affected by Waterlogging during Flowering and Bolling Stage in Cotton Difference of Physiological Characteristics of Cotton Bolls in Development of Fiber Thickening and Its Relationship with Fiber Strength Genotypic Differences in Some Physiological Characteristics during Cotton Fiber Thickening and Its Relationship with Fiber Strength Modified Backcross Pyramiding Breeding with Molecular Marker-Assisted Selection and Its Applications in Cotton
