摘　　要：温度是影响棉花生长发育的主要环境因子之一。高温对棉花的营养生长、花蕾发育、授粉、受精、棉铃发育、产量及品质造成严重影响。本文综述了高温对棉花雄蕊发育、花粉活力、花粉在柱头上的萌发、花柱中花粉管生长、雌蕊和棉铃生长等生殖过程和产量的影响以及耐高温品种的筛选方法,并对棉花耐高温研究的发展方向进行探讨,旨在为探索棉花耐热机理及培育耐高温品种奠定基础。Temperatures are one of main environmental factors for upland cotton（ Gossypium hirsutum L.） growth and development. High-temperatures seriously affects the vegetative growth,square development,pollination,fertilization,boll development and yield of upland cotton. In the present paper,the adverse effects of high-temperature on the reproductive process of stamen development,pollen grains viability,the germination pollen grains on stigma,the growth of pollen tubes in stigma,boll development and yield,as well as the method of screening cultivars with high-temperature tolerance in upland cotton were reviewed,and the development direction in researches of high-temperature tolerance of upland cotton were discussed. These are bases for exploring the mechanism and screening cultivars with hightemperature tolerance.
