Cotton nbers were induced from cotton ovule callus cells by suspension culture，floatculture or filter paper bridge culture．h was found that float culture or filter paper bridge culture was bener than suspension culture．APM and actinomycin D inhibit the fibe elongation．Cellobiose promotes its development. Polarity affects its culture．%用棉花胚珠切块诱导愈伤组织，经悬浮振荡培养、漂浮培养、滤纸桥法等方法诱导成纤维细胞。发现漂浮培养和改进的滤纸桥法对纤维的诱导效果比悬浮振荡培养的效果好。微管解聚剂APM和核酸抑制剂抑制纤维的生长，纤维二糖有一定的促进作用。极性对纤维的生长有影响。
