摘要/Abstract

摘要： 以棉花等基因系超短纤维突变体(Ligon Li1)及其野生型(Ligon li1)为材料，用胚珠离体培养方法，研究IAA（生长素）和GA3（赤霉酸）与纤维细胞伸长的关系。研究表明:（1）在含单激素IAA或GA3培养基内，离体诱导突变体胚珠产生的纤维长度分别约为1.86 mm和2.1 mm，比在对照（不含激素）培养基内的纤维长度分别增长86%和110%，说

Abstract: The effects of GA3 and IAA on fiber cell elongation were studied by in vitro cotton ovule culture and by comparison of a lintless mutant (Ligon cotton, Li1) with its wild type (li1) in upland cotton (Gossypium hirsutum L.). The results showed that: (1) In the media containing only IAA or GA3, the fi
