摘要： Background and aimsXinjiang is the largest cotton planting area in China. However, the perennial water shortage in Xinjiang restricts the development of the cotton industry, making drought one of the important limiting factors. The aim of this study was to evaluate the effectiveness of water-saving scheme and thiamine (Thi) application on alleviating the adverse effects of drought stress on the growth and development of cotton.MethodsIn this study, five Xinjiang-released cotton varieties (Jinken1775, Jinken1565, Huamian702, Zhongmian979, and Jinfeng2) were selected as the research object, and Xinluzao8 served as the drought-sensitive control. Comprehensive drought resistance index (D) of the drought resistance coefficient (DRC) of four yield and four quality traits were used to evaluate the drought resistant ability of the six cotton varieties under different water conditions and Thi spraying conditions.ResultsThe stage-specific irrigation strategy (60% during vegetative vs. 90% during the flowering and boll stage) concurrently maintained higher drought resistance across cultivars, with Jinken1565 exhibited the highest drought resistance. This scheme reduced irrigation by 26% while sustaining fiber quality. Exogenous 50 mM Thi further enhanced drought tolerance, reducing transpiration rate by 33% and blade damage by 55%. These results demonstrate that stage-specific water management optimizes drought adaptation in cotton cultivation under drought conditions.ConclusionsOur study suggests that a 26% water-saving scheme was proposed for most drought-resistant varieties planted in Xinjiang, and an appropriate scheme to achieve stable yield by Thi application during the early drought condition was proposed for varieties with low drought resistant ability.
