Impact of heat stress on agro-morphological, physio-chemical and fiber related paramters in upland cotton (Gossypium hirsutum L.) genotypes

Genetic Characterization and Performance Evaluation of Elite Cotton Strains for Morphological and Physio-Chemical Traits Under Heat Stress Conditions

“…Moreover, variations among cotton strains for these parameters were non-significant in replications except for plant height, which showed highly significant diversity among cotton strains with respect to plant height. Similar findings were also reported by Aslam et al, 2022;Hussain et al, 2023a;Hussain et al, 2023b andYousaf et al, 2023 who revealed significant variations among cotton genotypes for similar/same traits under heat stress conditions. The correlation coefficient analysis was executed to understand the magnitude and direction of association between studied plant traits in upland cotton strains under heat stress conditions (Table 4).…”

Quantitative Effects of Heat Stress on Fiber Related and Agronomically Important Parameters in Cotton (Gossypium Hirsutum L.)

“…The variations were highly significant for all the traits except the number of nodes per plant and monopods per plant, which were significant only. Similar observations were reported by several researchers who revealed the incidence of significant genetic variations in cotton genotypes under heat stress conditions Bhatti et al (2020a), Bhatti et al (2020b and Yousaf et al (2023). The correlation coefficient analysis was used to establish the relationship between studied plant traits in cotton genotypes under heat stress conditions.…”

Morphological and physio-biochemical responses under heat stress in cotton: Overview

“…The genomic variant that makes it highly resistant to consolidated stress [ 23 ]. A research on cotton ( Gossypium barbadense L.) found that a combination of drought and high temperatures had a negative impact on physiological processes such as development and advancement if compared to a single stress [ 24 , 4 ]. Cotton breeding initiatives should concentrate on selecting during combined drought and heat tolerance rather than just one of these conditions [ 25 ].The main objectives of this review are to focus on the environmental factors, such as temperature, heat and drought, influences the growth and development, morphology and physio-chemical alteration of cotton.…”

“…Fiber quality & lint parameters strongly predict atmospheric temperature and agricultural activities [ 37 ]. Because the development of photosynthetic activity, which is actually affected by high temperature, determines fiber strength and characteristics [ 4 ]. Higher temperature impedes cellulose synthesis, thus compromising the fiber length and strength [ 40 ].…”

“…Most cotton is cultivated in tropical and subtropical regions with temperature changes between 40 °C and 45 °C [ 2 ]. The temperature throughout a plant's growth season affects physiological and morphological growth and biomass production (S. [ 3 ]) [ 4 ]. Cotton loses its blooms and squares when the temperature exceeds upto 36 °C (S. A.…”
