摘要
通过对4个品系在同一地块连续3 a的试验,研究了不同年份间中长绒棉纤维品质的变化。结果表明:不同种植年度的气象差异对中长绒棉纤维品质的影响程度为伸长率>麦克隆值>比强度>长度>整齐度;遗传差异对麦克隆值和伸长率影响最大,比强度和长度次之,整齐度最小;气象差异对伸长率的影响大于遗传差异,遗传差异对麦克隆值的影响大于气象差异。
The fiber quality of four cotton strains were studied in the same field during three years. The results showed that the effects of meteorological difference on fiber quality of cotton is El. 〉 Mike 〉 Str. 〉 Len. 〉 Un.. The effects of heredity difference on fiber quality is Mike or El. 〉 Str. or Len. 〉 Un. ; The effects of meteorological difference on El. is more than heredity difference, and on Mike is less.
