摘　　要：通过盆栽控水称重法试验研究5个海岛棉品种在正常供水、中度水分胁迫、重度水分胁迫下的耗水量。对5个棉花品种地上部分的测量及分析,结果表明:海岛棉品种193在3个水分处理条件下的茎粗、节间数和株高表现突出,生长发育快,对缺水不敏感,属于抗旱型品种。TH-45在3个水分处理条件下的茎粗、叶片数和株高这三个性状较显著,生长发育快,对缺水不敏感,属于中度抗旱型品种。而新海14号相对其它棉花品种地上部分各个性状生长发育较慢,对缺水敏感,是耗水型品种。The main objective of this study was to investigate the water consumption of 5 sea island cotton by pot experiment. The results showed that the stem diameter, intemode number and plant height of sea island cotton 193 were found to be outstanding with fast growth and development, not to be susceptible to water deficiency and belonged to drought -/＇esistant variety. The stem diameter, leaf number and plant height of TH - 45 variety were found to be outstanding with fast growth and development, not to be susceptible to water deficiency under 3 water treaunents, Which belonged to be moderate drought- resistant variety. Thereby, Xinhai 14 had the characters of slow growth and development, was susceptible to water deficiency and belonged to water consumption variety.
