To better understand the adaptation mechanisms of the photosynthetic apparatus of cotton plants to water deficit conditions, the influence of water deficit on photosynthesis, chlorophyll a fluorescence and the activities of antioxidant systems were determined simultaneously in Gossypium hirsutum L.

Changes in cellular reactive oxygen scavenging enzymes were assessed in suspension-derived cells of cotton (Gossypium herbaceum) cv. Dhumad following culture with a commercial bovine hemoglobin (Hb) solution (Erythrogen) at 1:100-1:1000 (v:v). Mean (+/- SEM) fresh (f.wt.) and dry weights (d.wt.) of

This investigation focuses upon cell growth and antioxidant status in cultured cells of cotton (Gossypium herbaceum) cvs. Dhumad (salt-tolerant, TOL), H-14 (medium salt-tolerant, MED), and RAhs-2 (salt-sensitive, SEN) exposed to saline stress (50-200 mM NaCl). Mean (+/- SEM) callus fresh weight

OBJECTIVE Use of in vitro tests to search for relevant activities in bark of Ficus asperifolia Miq. and leaves of Gossypium arboreum L., used in Ghana for wound healing. METHODS Aqueous extracts of the relevant parts of the two species were tested for antibacterial activity against Staphylococcus

Silicon has been extensively researched in relation to the response of plants to biotic and abiotic stress, as an element triggering defense mechanisms which activate the antioxidant system. Furthermore, in some species, adding silicon to unstressed plants modifies the activity of certain

To determine NaCl effects on callus growth and antioxidant activity, callus of a salt-tolerant and a salt-sensitive cultivar of cotton was grown on media amended with 0, 75, and 150 mM NaCl. Callus of the salt-tolerant cultivar, Acala 1517-8 8, grown at 150 mM NaCl, showed significant increases in

Plant annexins represent a multigene family involved in cellular elongation and development. A cDNA encoding a novel annexin was isolated from a cotton (Gossypium hirsutum) fiber cDNA library and designated GhAnx1. This gene encodes a 316 amino acid protein with a theoretical molecular mass of 36.06

A field experiment was conducted to study the impact of solar UV-B (280-315 nm) and UV-A (315-400 nm) components on the growth and antioxidant enzyme activity in cotton plant (Gossypium hirsutum var. Vikram). Solar UV components were excluded by filtering the sunlight through selective UV-B (<315

Our previous research showed that standardized extract from the flowers of the Gossypium herbaceam labeled GHE had been used in clinical trials for its beneficial effects on brain functions, particularly in connection with age-related dementia and Alzheimer's disease (AD). The aim of this work was

The influence of plant interference and a mild drought on gas exchange and oxidative stress was investigated using potted plants of two cotton species (Gossypium hirsutum L. cv. Delta Pine 5415, and Gossypium barbadense L. cv. Pima S-7) and spurred anoda (Anoda cristata L. Schlecht.) of the

Background: Application of exogenous glycine betaine (GB) and exogenous salicylic acid (SA) mitigates the adverse effects of salinity. Foliar spraying with exogenous GB or SA alleviates salt stress in plants by increasing leaf gas

In this study, the role of specific components of different coping strategies to salt load were identified. A pot experiment was conducted with four cotton (Gossypium hirsutum L.) cultivars (differing in salt-sensitivity) under salinity stress. Based on observed responses in growth performance and

Increasing soil salinity suppresses both productivity and fiber quality of cotton, thus, an appropriate management approach needs to be developed to lessen the detrimental effect of salinity stress. This study assessed two cotton genotypes with different salt sensitivities to investigate the

Numerous studies have illustrated the need for antioxidant enzymes in acquired photosynthetic thermotolerance, but information on their possible role in promoting innate thermotolerance is lacking. We investigated the hypothesis that genotypic differences in source leaf photosynthetic

The use of fungicides for an effective control of plant diseases has become crucial in the last decades in the agriculture system. Seeds of cotton plants were treated with systemic and contact fungicides to study the efficiency of seed dressing fungicides in controlling damping off caused by
