The result indicated that fiber quality was positively correlated to cellulose content and negatively correlated to wax content. Furthermore, the investigation by electron microscopy demonstrated that the distribution location of pigment was signif- icant different in green and brown fiber cell, as well as the less the pigment content was distributed in fiber cell wall, the better the fiber quality was. Generally, the fiber quality of green cotton was the worst. However, the fiber quality of some brown cotton was even better than white cotton. This could be caused by the hybridization between brown and white cotton for fiber quality improvement. This study showed that the natural colored cotton fiber quality was related with cellulose, wax and pigment con- tent. natural colored cotton; ultrastructure; fiber quality; cellulose content; wax content 花是世界上最重要的经济作物之一 棉纤 系遥 我国彩色 育种研究起步较晚 但是进步很 维是
